Product Family Description

  • UV, VIS and IR Pass Ranges
  • VIS Can Be Used for Color Bandpass

A longpass filter has low transmission in the shortwave region (stopband) and high transmission in the longwave region (passband).

Longpass Filter Kits

Longpass filter kits are available in three different options: UV-VIS, VIS, or VIS-NIR. Each kit contains 8 filters in either 12.5mm diameter, 1" diameter, or 2" square. Wooden box with foam lining is included.

  • UV-VIS Kit Contains: WG 295, WG 305, WG 320, L 37, GG 400, GG 420, GG 435, GG 455
