Laser Line Filter 25mm Diameter Wavelength 976nm

VPFHT-25C-9760

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.

Guide
  • Please contact our Sales Division for customized products. (customized outer diameter, wavelength characteristic, etc.)
  • We also offer interference filters VPF with cutting range that is broad.
  • WEB Reference Catalog Code/W3119
Remark -
Attention
  • Characteristics of the interference filter is depending on the incident angle. If it is tilted from the optical axis, then the center transmitting wavelength is shifted toward the short wavelength, and transmittance also decreases. Please make sure to incident at 0 degrees collimated light or close to collimated (parallel) light to the optical axis. Angle dependence will increase as half-width range of transmittance becomes narrow.
