Tydex Low Pass Filters perform in wavelength range from IR to MM. They have high transmittance in pass band and low transmittance (<0.1%) in stop band.
Tydex Band Pass Filters can have any pass band in the range from 0.3 to 15 THz (from 1000 to 20 μm).
They settle the problems of quasioptical filtration of radiation in THz range and permit to get high degree of monochromatization while the aperture ration of device is also high.
Tydex THz filters with clear aperture 24, 35, and 47 мм are available from stock.
Alternate sizes and custom designs are available upon request.
