Long-pass (LP) filters, also known as IR Long-pass filters are optical devices used in various fields of science and technology to selectively transmit longer wavelengths of light while blocking or attenuating shorter wavelengths.
This page highlights Shalom EO’s standard long-pass filters. Our products feature sharp cut-on slopes, rejection depths from OD3 to OD6. The transmission range ranges from UV to IR with high transmission rates from 75% to 98%.
