Product Family Description

Our High Performance Longpass filters feature high transmission in the pass band combined with superior blocking in the rejection band. With a rejection band optical density of 4.0 combined with >91% in the pass band these filters are ideal for a wide variety of applications. Eliminate stray light by creating custom bandpass filters when combined with our TECHSPEC® High Performance Shortpass Filters.

Note: These filters are optimized for high spectral performance rather than high Laser Induced Damage Thresholds (LIDT). A typical LIDT for these filters is 1 J/cm2 @ 532nm, 10ns. Please contact us if you require a filter with a higher LIDT value.

Our TECHSPEC® Rotating Filter Wheel can be used for applications requiring a variety of filters.
