LohnStar Optics, Inc. has been providing custom, highly-specialized IR thin film coatings for medical, research, industrial, military and national space defense applications since 1997.  Coatings are designed using the latest computer software, with state-of-the-art optimization techniques. Our vacuum systems can accommodate optics up to 38". We pride ourselves in being able to meet any coating needs using our 20+ years of experience and expertise.

• Some of our specialties include:

• Ultra Low-Loss Supermirrors from 1µm-14µm

• Quantum Cascade Laser coatings (AR, BBAR, PR, HR Coatings)

• High damage threshold coatings for CO2, Er:YAG and high-power chemical lasers at wavelengths from 2-16 microns

Sputtered thin film filters from 250nm out to 50+ microns, including diamond-like carbon. 

• We also provide finished optics in partnership with our fabrication and polishing associates.  Our vacuum systems can accommodate optics up to 38", in small and OEM quantities.
