Thorlabs offers a complete selection of blackout materials that are designed to control stray or ambient light, which can adversely affect experiments or components within a setup (e.g. photodetectors). These materials are especially beneficial when using high-gain detection equipment, such as in photon counting experiments, since high-gain detectors are easily saturated by room light. In ellipsometry and certain polarimetry techniques, blackout materials may be used to prevent reductions in accuracy caused by ambient light.

We offer blackout fabric, hardboard, posterboard, self-adhesive black flocked paper, aluminum foil, masking tape, and vertical blinds.

Please note that on this page, only the Laser Safety Fabric is laser safety rated. All other items on this page are not intended to be used for laser safety. For more information, please see the Laser Safety tab above.

Laser Safety and Classification

Safe practices and proper usage of safety equipment should be taken into consideration when operating lasers. The eye is susceptible to injury, even from very low levels of laser light. Thorlabs offers a range of laser safety accessories that can be used to reduce the risk of accidents or injuries. Laser emission in the visible and near infrared spectral ranges has the greatest potential for retinal injury, as the cornea and lens are transparent to those wavelengths, and the lens can focus the laser energy onto the retina.

Shutter and Controllers Laser Safety Signs

Safe Practices and Light Safety Accessories

  • Thorlabs recommends the use of safety eyewear whenever working with laser beams with non-negligible powers (i.e., > Class 1) since metallic tools such as screwdrivers can accidentally redirect a beam.
  • Laser goggles designed for specific wavelengths should be clearly available near laser setups to protect the wearer from unintentional laser reflections.
  • Goggles are marked with the wavelength range over which protection is afforded and the minimum optical density within that range.
  • Laser Safety Curtains and Laser Safety Fabric shield other parts of the lab from high energy lasers.
  • Blackout Materials can prevent direct or reflected light from leaving the experimental setup area.
  • Thorlabs' Enclosure Systems can be used to contain optical setups to isolate or minimize laser hazards.
  • A fiber-pigtailed laser should always be turned off before connecting it to or disconnecting it from another fiber, especially when the laser is at power levels above 10 mW.
  • All beams should be terminated at the edge of the table, and laboratory doors should be closed whenever a laser is in use.
  • Do not place laser beams at eye level.
  • Carry out experiments on an optical table such that all laser beams travel horizontally.
  • Remove unnecessary reflective items such as reflective jewelry (e.g., rings, watches, etc.) while working near the beam path.
  • Be aware that lenses and other optical devices may reflect a portion of the incident beam from the front or rear surface.
  • Operate a laser at the minimum power necessary for any operation.
  • If possible, reduce the output power of a laser during alignment procedures.
  • Use beam shutters and filters to reduce the beam power.
  • Post appropriate warning signs or labels near laser setups or rooms.
  • Use a laser sign with a lightbox if operating Class 3R or 4 lasers (i.e., lasers requiring the use of a safety interlock).
  • Do not use Laser Viewing Cards in place of a proper Beam Trap.

 

Laser Classification

Lasers are categorized into different classes according to their ability to cause eye and other damage. The International Electrotechnical Commission (IEC) is a global organization that prepares and publishes international standards for all electrical, electronic, and related technologies. The IEC document 60825-1 outlines the safety of laser products. A description of each class of laser is given below:

Class Description Warning Label
1 This class of laser is safe under all conditions of normal use, including use with optical instruments for intrabeam viewing. Lasers in this class do not emit radiation at levels that may cause injury during normal operation, and therefore the maximum permissible exposure (MPE) cannot be exceeded. Class 1 lasers can also include enclosed, high-power lasers where exposure to the radiation is not possible without opening or shutting down the laser.  Class 1
1M Class 1M lasers are safe except when used in conjunction with optical components such as telescopes and microscopes. Lasers belonging to this class emit large-diameter or divergent beams, and the MPE cannot normally be exceeded unless focusing or imaging optics are used to narrow the beam. However, if the beam is refocused, the hazard may be increased and the class may be changed accordingly.  Class 1M
2 Class 2 lasers, which are limited to 1 mW of visible continuous-wave radiation, are safe because the blink reflex will limit the exposure in the eye to 0.25 seconds. This category only applies to visible radiation (400 - 700 nm).  Class 2
2M Because of the blink reflex, this class of laser is classified as safe as long as the beam is not viewed through optical instruments. This laser class also applies to larger-diameter or diverging laser beams.  Class 2M
3R Lasers in this class are considered safe as long as they are handled with restricted beam viewing. The MPE can be exceeded with this class of laser, however, this presents a low risk level to injury. Visible, continuous-wave lasers are limited to 5 mW of output power in this class.  Class 3R
3B Class 3B lasers are hazardous to the eye if exposed directly. However, diffuse reflections are not harmful. Safe handling of devices in this class includes wearing protective eyewear where direct viewing of the laser beam may occur. In addition, laser safety signs lightboxes should be used with lasers that require a safety interlock so that the laser cannot be used without the safety light turning on. Class-3B lasers must be equipped with a key switch and a safety interlock.  Class 3B
4 This class of laser may cause damage to the skin, and also to the eye, even from the viewing of diffuse reflections. These hazards may also apply to indirect or non-specular reflections of the beam, even from apparently matte surfaces. Great care must be taken when handling these lasers. They also represent a fire risk, because they may ignite combustible material. Class 4 lasers must be equipped with a key switch and a safety interlock.  Class 4
All class 2 lasers (and higher) must display, in addition to the corresponding sign above, this triangular warning sign  Warning Symbol

Thank you for contacting Thorlabs. We do not have damage threshold data for those blackout materials. Only the LPCM1 laser safety fabric on this page is rated for laser safety. We do not recommend using other blackout materials with any pulsed or CW laser from which damage is a concern. Please see the Laser Safety tab for better laser safety alternatives.

Hi, we are looking for a solution to black-outour lab, for biomedical imaging and microscopy. One option, is to use an already existing laser protection curtain and cover it with a black material. Would the self-adhesive paper be suitable to be applied to a curtain, without breaking or ripping? thanks in advance, Alex
tfrisch  (posted 2017-09-01 10:20:18.0)
Hello, thank you for contacting Thorlabs. The adhesive paper certainly would not slide on the track as well as our laser safety curtains, but I would not expect them to tear if they are not disturbed. I'll reach out to you directly to discuss handling.
lukas.arnhold  (posted 2017-06-19 14:48:12.57)
We want to use this product to shield samples. Our laser power is some mW. Do you have any reflectance data, especially under 4000 wavenumbers, to optimize the data analysis?
tfrisch  (posted 2017-07-01 10:55:04.0)
Hello, thank you for contacting Thorlabs. While we do not have reflection data for BKF12 below 4000 cm-1 (above 2.5um wavelength), Aluminum is very absorptive in the IR, and I would expect almost no transmission through even 50um of foil. I will reach out to you directly to discuss your application.

I have a setup with a strong laser (4 W at 1064 nm) inside an enclosure; the enclosure is made of untreated aluminum which is highly reflective. To prevent possible reflections of the laser beam, I am thinking of sticking BKF12 aluminum foil to the inner walls of the enclosure. Would this pose a fire risk, i.e. could the foil be burnt by the laser? Thanks! Jerry.

Response from Tim at Thorlabs: Our laser safety barrier is more suitable for high power (http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=4372). Alternatively, we do have beam traps, http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1449, which may suit your needs. I would not recommend substituting a proper high power laser safety barrier with TB4. I see you have contacted us with further questions and we will contact you directly to discuss this further.

Black Flocked Self-Adhesive Paper

Black Paper Reflectivity
Click to Enlarge
Data Obtained at 8° AOI
  • Self-Adhesive
  • Does Not Shed Dust or Lint
  • 30" x 30" x 0.012" (76.2 cm x 76.2 cm x 0.305 mm) Without Backing
  • Not Intended for Use in Laser Safety Applications

Flocked paper is a self-adhesive material made of many fine fibers. It has a textured, matte-black surface. When viewed at from low angles, it absorbs virtually 100% of the visible light that strikes it. The fibers will not shed dust or lint, unlike some velvet and felt materials. The approximate compressed thickness of the flocked paper is 0.015" (0.381 mm) with the backing and 0.012" (0.305 mm) without the backing.

Image contrast can suffer due to stray light reaching the focal plane of many applications where the light path travels through a tube or other enclosed area. Applying a flat-black paint to the inside may help, but a textured matte-black surface is a much more effective light trap.

Caution: Do not cut the BFP1 black flocked paper with a laser cutting tool, as the BFP1 burns easily and may catch fire. It is suggested that you use a utility knife or other sharp edged tool to cut the BFP1.

  • 1" (25 mm) and 2" (50 mm) Wide Versions Available
  • Paper-Based Masking Tape for General Purpose or Blackout Applications
  • Aluminum Foil Tape for Total Blackout Applications
  • Can be Torn by Hand and Removed Easily Without Leaving Residue
  • Not Intended for Use in Laser Safety Applications

Thorlabs offers a standard and high-performance black masking tape, as well as an aluminum foil masking tape. All types of tape can be torn by hand, are easy to remove, and do not leave a residue. The T137-1.0 and T137-2.0 black masking tape can be used for general applications. For applications requiring minimal ambient light transmission, the T743-1.0 or T743-2.0 high-performance black masking tape is recommended. For total blackout requirements or high-power applications, we offer the T205-1.0 or T205-2.0 non-reflective, flame-retardant aluminum tape. This foil tape has been tested to withstand up to 10 seconds of exposure from a 20 W, Ø6 mm, 10.6 µm laser beam.

In the photographs shown above, a collimated LED (Item # M530L2-C2) with approximately 170 mW output power was used to illustrate how the T743-2.0 high-performance tape allows very little light transmission as compared to the T137-2.0 standard black masking tape. The table below gives the measured power and percent transmittance when various wavelengths of light were incident upon each type of tape.

Thorlabs' laser safety fabric is designed to withstand high laser energy up to EN 12254: 2010(E) certification with the flexibility to be cut into custom sizes to suit experimental needs. The laser rated material is made of a rubber compound fabric, which is the same material used to make our laser safety curtain panels. The table to the right gives the certifications applicable for certain wavelength regions; to see the complete EN 12254: 2010(E) certification, please click here. The customizable nature of this fabric makes it ideal for creating window covers and building custom enclosures for experiments and optical systems. Please ensure that the cutting tool you are using is sharp in order to reduce frayed edges. A red laser safety label, as seen in the image to the right, is attached to each sheet of 1.0 m and 3.05 m long fabric.

Some material may need to be trimmed off either end of the LPCM10 prior to use. However, a minimum of 10.0 m of usable material is included. Please note that the LPCM10 is shipped in a crate weighing over 60 kg (132 lbs) and requires a forklift for transport. The roll itself is approximately 30 kg (66 lbs); a team lift is recommended.

  • Blackout Material
  • 1.7 m (66.9") Drop

These blackout blinds are made from a black, rubberized fabric. Designed for applications where light exclusion is required, such as laboratories and dark rooms, they can be used to keep stray light out of photosensitive setups. They are also useful for preventing bright sources from being visible by people outside the lab. The fabric is totally opaque, and the blinds are manually operated by a side chain. They can be attached to the wall or window recess using the two brackets and four screws that are supplied. Please note that the blinds are not intended for use as a laser curtain since the material is not flame retardant. The material has also not been tested for cleanroom compatibility.
