TECHSPEC® Longpass Filters

Longpass Filters
  • Sharp Cut-On Wavelength
  • High Rejection/Transmission Efficiency
  • Precision Fused Silica Substrate

Our TECHSPEC® Longpass filters are designed to have a sharp transition from reflection to transmission, making them ideal for various applications. Available in a variety of cut-on wavelengths, these filters are designed for fluorescence and order sorting applications. Eliminate stray light by creating custom bandpass filters when combined with our TECHSPEC® Shortpass Filters. A single layer AR coating on the back surface enhances the overall efficiency of each filter.

Our longpass filters are available in a number of kit configurations. Visible filter kits are available in 25nm increments (featuring 14 filters) or 50nm increments (featuring 7 filters). NIR Kits are available in 50nm increments (featuring 8 filters). All filter kits are available in 12.5, 25, and 50mm diameters.
