Product Family Description

Broad Transmission and Rejection Ranges
Sharp Slope for Effective Spectral Discrimination
Combine with Longpass Filter for Custom Bandpass Ranges

These High Performance Shortpass Filters are designed with superior blocking in the rejection band while maximizing transmission in the pass 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.

These filters can be combined with our TECHSPEC® OD 4.0 Longpass Filters to create a customized precision bandpass filter. The VIS Shortpass Filter Kits include 7 filters between 400-700nm and both are ideal for integration with our filter wheels.

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.
