Tydex offers spectral splitters for applications where NIR and MIR radiation has to be reflected without transmission degradation in THz range.
NIR-THz spectral splitter is used for separation of pump radiation (centered in the wavelength range 790-800 nm) from THz radiation in Ti:Sapphire laser and MIR-THz spectral splitter – for separation of pump radiation (9.6 μm and 10.6 μm) from THz radiation in THz laser optically pumped by CO2 -laser.
Common specification:
Splitter Type NIR-THz spectral splitter MIR-THz spectral splitter Material of substarate - HRZF-Si - THz-grade crystal quartz Dimensions tolerance, mm +/-0.25 Clear aperture, % 90 Surface quality, scr/dig 60/40 Surface accuracy, mm +/-0.01 deviation from ideal plane Coating High-reflection dielectric coating (R>90%) @ 730-860 nm High-reflection dielectric coating (R>90%) @ 9-11μm Angle of incidence, arc. grad. 45 |
