Shortwave pass filters allow shorter wavelengths than the cut-off wavelength to transmit, while it blocks/reflects longer wavelengths.

Notch Optics offers high performance OD 4.0 shortpass filters.

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

High-Performance OD 4.0 Shortpass Filters are engineered to provide superior blocking in the rejection band while ensuring maximum transmission in the pass band.

These filters feature an optical density of 4.0 in the rejection band, coupled with a transmission rate of ≥ 91% in the pass band, making them suitable for a wide range of applications.

For creating a customized precision bandpass filter, High-Performance OD 4.0 Shortpass Filters can be paired with our OD 4.0 Longpass Filters.

Please note that these filters prioritize high spectral performance over high Laser Induced Damage Thresholds (LIDT). The typical LIDT for these filters is 1 J/cm² at 532nm, 10ns. If you require a filter with a higher LIDT, please contact us for more information.
