Request InfoOseir Ltd.TAMPERE, Finland, July 21, 2008 – Oseir has unveiled a new tunable multistage optical bandpass filter for use in practical spectral two-dimensional imaging applications. The filter has a tuning wavelength range from 450 to 800 nm and the bandwidth can be optimized by the number of stacked filter elements. A basic four element filter stack is 40 x 50 x 35 and weighs 250 grams, with a diameter filter aperture of 12 mm. Custom sizes can be made available upon request. Features of the filter include a compact size, a wide aperture with high quality image transmission and strong blocking bands.
