The Interference Filters feature a spectral range starts from 250 nm to 5000 nm. These various filters can be apply as wavelength selectors in astrophysics, clinical chemistry, material analysis, quality control. This product have the specification that contains a mount diameter of 25.4 mm (+0.0/ -0.2 mm), clear aperture of > 18 mm, surface quality of 60/40 S/D, blocking of < 0,01% and bandwidth tolerance of ±20 %. Meanwhile, the Altechna Co. Ltd produces different filters such as biomedical bandpass filters for biomedical instrumentation, fluorescence filters used for sharp slopes, burried blocking, low spectral crosstalk, high transmission and environmental durability.
