Products Description
BP590nm Bandpass Filter | FWHM 100nm, High Transmission Optical Filter
The OPTOStokes BP590nm optical filter is engineered for high-performance optical systems requiring precise spectral isolation in the yellow-orange wavelength region. Featuring a central wavelength (CWL) of 590nm and a broad full-width at half-maximum (FWHM) of 100nm, this high-transmission bandpass filter delivers exceptionally high throughput (T > 90%) across the 555-625nm passband while providing deep out-of-band blocking. Designed to maximize signal-to-noise ratio in demanding optical setups, it is an essential component for bio-imaging, industrial inspection, and spectroscopic applications.
