• 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

Thorlabs offers two types of black masking tape and an aluminum foil tape. All types of tape can be torn by hand, are easy to remove, and do not leave 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, a high-performance black masking tape (T743-1.0 or T743-2.0) is recommended. For total blackout requirements or high-power applications, we offer a non-reflective, flame-retardant aluminum tape (T205-1.0 or T205-2.0). 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 (M530L2-C2) with approximately 170 mW output power was used to illustrate how the T743-2.0 allows very little light transmission as compared to the T137-2.0 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.

Laser (Wavelength)	Measured Power (% Transmittance)
	Incident Power	T137-2.0 (Masking Tape)	T743-2.0 (High-Performance Masking Tape)	T205-2.0 (Aluminum Foil Tape)
CPS180 (635 nm)	1.07 mW (100%)	1.34 µW (0.13%)	0.90 µW (0.08%)	Zero (0%)
CPS182 (635 nm)	4.79 mW (100%)	5.92 µW (0.12%)	0.24 µW (<0.01%)	Zero (0%)
HRS015 (632.991 nm)	1.41 mW (100%)	3.36 µW (0.24%)	0.012 µW (<0.01%)	Zero (0%)
LDM850 (850 nm)	20.34 mW (100%)	28.74 µW (0.14%)	1.04 µW (<0.01%)	0.0006 µW (<1 x 10-5%)

  1/2" Wide Vinyl Tape
  108' (32.9 m) Long Roll
  Available in Red, Green, or Yellow

Colored rolls of vinyl tape are ideal for color coding fibers, cables, tools, and samples. The semi-gloss finish can be written on with permanent marker, and the tape can be used in environments from 40 °F to 170 °F (5 °C to 76 °C), although it is best to apply the tape at room temperature.

This 3M tape is 10.2 mil thick and double-coated with 375 adhesive. The substrate or carrier is made from PVC with white paper, green print liner. The tape features a high peel and shear strength, excellent resistance to UV light, good solvent and plasticizer resistance, and long-term temperature performance up to 158 °F. There are many applications for the tape including mounting optics, hardware, fiber, sensors, etc.

• Thermally Conductive Double-Sided Acrylic Adhesive Tape
• Great Alternative to Heat-Cured Adhesives, Screw Mounting, or Clip Mounting
• Provides a High Bond Strength to a Variety of Surfaces
• Can be Removed without Damaging Parts

The thermally conductive, double-sided tape consists of a superior bond strength, pressure-sensitive acrylic adhesive loaded with titanium diboride and applied to an expanded aluminum carrier. The tape is embossed with an innovative pattern for maximum conformability and minimal air pockets and offers excellent thermal, mechanical, environmental, and chemical properties. Our thermally conductive doubled-sided tape can bond heat sinks and thermal plates to components without the use of clips, screws, other mechanical fasteners, or additional thermal compounds and can be removed after the application without damage to the component.

• Removes Easily without Leaving a Residue
• Wide Usage Range: -100 °F to 500 °F (-73°C to
  260 °C)
• Substitute for Standard Electrical Tape in Cooled and Heated Environments
• Excellent for Insulation, Masking, or Packaging Applications

This high-temperature tape is made from Dupont's trademark Kapton film and a cross-linked silicon adhesive. The tape is flame-resistant, will withstand short-term intermittent temperatures to 600 °F, and can be used as electrical and thermal insulation. Compared to electrical tape, it removes easily without leaving a residue, making it ideal for packing, temporarily securing components, or powder coating applications.

Kapton tape is commonly used as a wire and cable wrap as well as to protect electrical components during soldering. It is effective for both hand-soldering and mass soldering applications, such as wave soldering. In the electronics industry, Kapton tape is applied to circuit boards before wave soldering to shield gold fingers from the solder material and prevent unwanted electrical connections. The tape is also easy to trim with a razor blade and can be used as a temporary dust cover for ports in devices.
