Product Family Description

Sharp Cut-On Wavelength
High Rejection/Transmission Efficiency
Precision Fused Silica Substrate
Variety of OD 2.0 Longpass Filter Kits are Available

Our TECHSPEC® OD 2.0 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® OD 2.0 Shortpass Filters. A single layer AR coating on the back surface enhances the overall efficiency of each filter.

Note: Due to supply chain issues, our kits may be delivered with an alternative packaging solution in place of a wooden box. For any questions, please contact [email protected].
