    Westerville, OH, USA & Quebec City, Canada, February 1, 2007 ¡ª 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 ¡ª 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.
