New 30 µm Far IR Filter Successfully Passes Field Test

A long wave pass filter with a 30 µm cut-on has been successfully tested at the Institut National d'Optique (INO), Canada's world-class center of expertise for research in optics and photonics. Supplied by Lake Shore Cryotronics of Westerville, OH, the filter is based on a novel porous silicon technology that provides excellent thermal and mechanical properties -- even at cryogenic and elevated temperatures. The filters are available in a long pass design with multiple standard cut-on wavelengths ranging from 5 to 150 µm.

Westerville, OH & Quebec City, Canada (PRWEB) February 2, 2007 -- A long wave pass filter with a 30 µm cut-on has been successfully tested at the Institut National d'Optique (INO), Canada's world-class center of expertise for research in optics and photonics. The filter, supplied by Lake Shore Cryotronics of Westerville, OH, is based on a novel porous silicon technology. This all-silicon design provides excellent thermal and mechanical properties -- even at cryogenic and elevated temperatures.

INO research scientist, M.S. Georges Baldenberger, mentioned, "We specified Lake Shore's filter because of its promising spectral performance and off-the-shelf availability. Throughout our testing, Lake Shore has provided excellent quality of service in support of our research efforts."

M.S. Baldenberger further commented, "The filter performed very well and enabled us to achieve the experimental results we needed. It had very good behavior in the mid-IR wavelength range, which had to be absolutely rejected." As a result of this successful test, INO has placed a follow-up filter order.

Lake Shore Cryotronic's optical filters are currently available in a long pass design with multiple standard cut-on wavelengths ranging from 5 to 150 µm. Research and development work continues to further extend the performance capabilities of this technology and also to develop a similar technology for narrow band pass filters in the mid- and far-infrared spectral regions.
