Notch Filter 25mm Diameter Synthetic Fused Silica 355nm

NF-25C05-27-355

Notch filter is a filter that cuts only a specific wavelength. It is not the same as the interference filter which transmits only a specific wavelength. By using a dielectric multilayer coating the product has very high stability and has environmental resistance.
◦Four types are available 355nm, 532nm, 633nm and 1064nm.
◦Because it is a dielectric multilayer coating, there is almost no absorption by the coating.
◦By using in combination with other filters, it can also be used as filter sets for Bio-Imaging.

Guide
  • Please contact our Sales Division for customized products. (customized on outer diameter, wavelength characteristic, etc.)
Remark -
Attention
  • If the light incident angle is other than 0 degrees, the transmittance characteristics may change. In the normal situation, when the incident angle changes, the wavelength may shift to the long wavelength side.
  • Notch filter has a durable structure to the high temperature, but if it is put close to the lamp that emits a powerful heat ray (e.g. mercury lamp), it will not be guaranteed for the performance of the filter and safety.
