Optical Filters

Asahi Spectra offers various types of optical filters as standard. Our optical filters are manufactured by hard coating, such as ion assisted deposition (IAD) and magnetron sputtering (MS). These coating methods achieve hard coating, excellent durability for environment (humidity, low or high temperature, thermal shock or vacuum) and stability of spectral performance.

Optical Instruments
