IRphotonics Announces Moldable Glass for Large Scale UV to Mid IR Applications

Allows production of finished aspherical and diffractive lens geometries in volume

MONTREAL, QUEBEC--(CCNMatthews - April 2, 2007) - IRphotonics, a leading supplier of mid infrared materials, today announced it has successfully completed molding tests of its proprietary fluoride glass with optical industry leaders. The test results confirmed that IRphotonics' UVIR™ amorphous glass can be easily molded into a variety of optical components that include aspherical lenses. IRphotonics' UVIR™ glass exhibits a broad transmission window ranging from UV to 8 micronsm that makes it an ideal material for various defense and commercial applications that include thermal imaging and spectroscopy.

"We are very excited by the excellent molding results we obtained. We have demonstrated compatibility with existing lens molding techniques that provide a cost-effective way to manufacture complex optical components." said Eric Geoffrion, CEO of IRphotonics. "It is an important milestone in our plan to broaden the applications of our UVIR™ glass."

The low refractive index of the UVIR™ glass combined with its exceptional transmission characteristics provides over 91% transmission from 350 nm to 5 micronsm and more than 80% transmission from 220 nm to 6.2 micronsm (3.6 mm thick window). The UVIR™ fluoride glass also exhibits a number of unique physical characteristics that include a negative dn/dT (decrease of refractive index with rising temperature) and a thermal expansion coefficient that closely matches that of aluminum and stainless steel.

The UVIR™ glass amorphability proves useful for making large optical pieces. Moreover, different dopants can be incorporated in the UVIR glass to turn it into a broadband optical filter.

IRphotonics will be exhibiting at the 2007 Defense & Security Symposium, April 10-12 in Orlando, booth 1452.
