Tunable optical bandpass filter from Oseir

Aug. 30, 2008
The tunable multistage optical bandpass filter from Oseir Ltd. is designed for use in practical spectral 2D imaging applications. It can be connected to equipment such as CCD cameras or microscopes, or used with a white light source to produce a tunable light source.

The tunable multistage optical bandpass filter is from Oseir Ltd. designed for use in practical spectral 2D imaging applications. It can be connected to equipment such as CCD cameras or microscopes, or used with a white light source to produce a tunable light source.

The filter can be tuned in the wavelength range from 450 nm up to 800 nm and the bandwidth can be optimized by the number of stacked filter elements.

The size of a four element stack is 40 x 50 x 35 and it weighs 250 grams. The diameter of the filter aperture is 12 mm. Custom sizes can be made available by request.

Other wavelength ranges will also be possible by selecting the optical materials to produce a filter for NIR or UV ranges.

A basic four element filter in the above specified wavelength range is available in Q4 2008.
