Bandpass filters

Share this on social media:

Laser Components has introduced pyroelectric and lead salt detectors to the IR market. Fourteen standard bandpass filters are sawn up hexagonally and integrated into pluggable filter mounts with an inner diameter of 8.5mm, with an aperture of 6mm. Wavelengths range from 3.33μm to 7.30μm, having full width half maximum values from 60nm to 600nm. These filters use silicon substrates providing blocking to 10μm, with 13 out of the 14 filters being angle optimised.
