Hi. What is the damage threshold for this mirror? I am considering to use this mirror for high power pulsed laser. Thx

Thank you for reaching out to us regarding this damage threshold inquiry. We do not have a general damage threshold to share here, but I have emailed you directly to learn more about your laser parameters. Given those values, we should be able to determine whether or not your laser will be compatible with these mirrors.

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.
