Product Family Description

Cut-On Slope <1%
Rejection OD ≥ 4.0
≥91% Transmission in Pass Band
Variety of OD 4.0 Longpass Filter Kits Available

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.
