Custom Size Optical Glass Optical Filter

Product description

The longpass filter, with a center wavelength of 840 nm, is designed to effectively transmit wavelengths from 0.7 to 1.7 μm while blocking shorter wavelengths. This filter is ideal for applications in fluorescence microscopy and other optical systems requiring high transmittance. With a 90% transmittance and an optional 95%, it ensures optimal performance in light-sensitive environments.

Key Features
