Features

  • 45° Angle of Incidence
  • Ravg > 99.7% from 520 to 647 nm

The Kr-Ion laser line mirror has a specialized coating that provides a high reflectance over the 520 - 647 nm wavelength range. These mirrors are suitable for use with the output beam from large-frame, high-powered CW (continuous wave) Kr-Ion lasers.

Our Ø19 mm mirror is specifically designed to fit our Polaris® Fixed Optic Mounts for laser system design and other OEM applications. This diameter provides a larger clear aperture than Ø1/2" optics while allowing the mounts to maintain a Ø1” footprint.

Hi, Could you please let me know the reflectance of this mirror at 400-410 nm range? I need it to be AR coated in this range and with reflectance in 520-650 nm. Cheers.

Response from Bweh at Thorlabs USA: We actually have this data on the website. Just below the plot at the following link is the excel data between 200nm and 25um: http://www.thorlabs.de/newgrouppage9.cfm?objectgroup_id=807&pn=NB1-J11. I have also sent this to you by email.

Response from Buki at Thorlabs: Thank you for your interest in Thorlabs products. The NB1-J11 is designed to provide an average of 99.7% across a wavelength range of 520-647nm. We have broadband dielectric mirrors with a 400 - 750nm coating that provides an average of 99% reflectivity. We will contact you to see if our broadband mirror could be suitable for your application.

Please could you supply a coating curve for this mirror please (NB1-J11) for the 400-700nm range? Many Thanks.

A response from Greg at Thorlabs to kyle.frische: We currently do not offer a Kr-Ion mirror for 406 - 413 nm. However, our -E02 coated mirrors offer better than 99% reflectance from 400 nm to 750 nm.

I need a Kr-Ion mirror for 406-413nm Krypton lines.
