Photonics Tech Briefs INSIDER

LASER COMPONENTS (Bedford, NH) has begun introducing pyroelectric and lead salt detectors to the market. With this in mind, they also now offer low-cost accessories such as new IR filter sets. Fourteen standard bandpass filters are sawn up hexagonally and integrated into pluggable filter mounts with an inner diameter of 8.5 mm, with an aperture of 6 mm. Wavelengths range from 3.33 μm to 7.30 μm, having full width half maximum values from 60 nm to 600 nm. These filters use silicon substrates providing blocking to 10μm, with thirteen out of the fourteen filters being angle optimized.
