Laser Line Filter 12.5mm Diameter Wavelength 491nm
VPFHT-12.5C-4910
This filter can extract light in a specific wavelength range. Very high transmittance can be obtained in the transmission range. Outside the specified transmission wavelength range the transmission decrease is steep and light is not transmitted almost close to the transmission range.
◦Since the coating is a dielectric multilayer the absorption is small and transmittance is high. It enables the separation of the wavelength specified light efficiently.
◦The filters are metallically framed which make it easy to be mounted into a holder.
◦Large choice of spectrum, range from UV 325nm to IR 1064nm are available.
