High Power MicroSpot Focusing Objectives

Features

  • Designed for High-Power Industrial Nd:YAG Lasers
  • Magnifications: 5X, 10X, or 20X
  • Design Wavelengths: 532 nm or 1064 nm

Specifications

  • Fused Silica Lenses
  • Better than 96 to 98% Transmission within Design Spectral Region
  • Damage Threshold of 500 MW/cm2 for 20 ns Pulses @ 20 Hz (532 or 1064 nm)

Thorlabs' High-Power Nd:YAG MicroSpot Focusing Objectives are designed to focus high-power Nd:YAG laser beams to a diffraction-limited spot. They offer a damage threshold of 500 MW/cm2 at 532 nm or 1064 nm (20 ns, 20 Hz pulses). The transmission window of the objective extends from 250 nm to 1600 nm, and the objective is capable of producing a nearly diffraction-limited spot in the spectral range from the visible to the near-infrared.

Do you have microscope objectives at 532nm and 800nm with atleast 12-15mm entrance aperture?

Response from Bweh E. at Thorlabs: Thanks for contacting Thorlabs. At this time, we do not carry such objectives that meet your requirements. We however have several other objectives at the following page: http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1044.

Response from Jeremy at Thorlabs: We do not currently have these short focal length objectives for high power application. I have logged this in our internal forum and we will look into whether we could make this.

Do you have 40times or 60 times high power focusing objective 1064nm or 532nm? I need them in these days. Please let me know if you have them. Thank you!

Is the transmission for the 1064nm version of the objectives similar at 1037nm?

Response from Tim at Thorlabs: Yes. The number of surfaces in each objective is different and therefore deviation away from the design wavelength will have more of an impact on transmission for the 20X vs the 10X, for example. However, at your desired wavelength the total transmission for each is similar.

Response from Tim at Thorlabs: Thank you for your feedback on the LMH-10X-532. I am looking into the materials we use for this objective and will post an update soon.

I'm intersted in a microscope objective that would be made of non magnetic material. Do you have any data about the housing material of that lens? THanks

Response from Javier at Thorlabs to last poster: Thank you very much for contacting us. For this objective, the absorption in the glass itself is almost negligible, and if we assume 3.5% loss at each surface we would end up with a total transmission in the neighborhood of 80%. However, keep in mind that the chromatic shift of roughly 0.2 mm will slightly affect the performance of this objective. Also, we do not currently have an objective specifically designed for operation at 980 and 1550 nm. Please contact us at techsupport@thorlabs.com if you would like to discuss your application a bit further.

I am working with this objective (LMH-10X-1064), but I have beam at 1550nm. So I want to know the transmission spectrum of this objective especialy for 1550nm). Is there any particular objective design to work at 980nm and 1550nm?

A response from Adam at Thorlabs to Ilday: There was a server glitch and we are working to bring this page online. Please note that we do have stock on most of these objectives and they can be ordered direct through our sales department, sales@thorlabs.com or 973-300-3000, while these parts are not on the website. I will email you with more information.

I wanted to purchase this product, which was available until yesterday, however it has disappeared from the webpage. Is that a server glitch or did you discontinue the product?
