FF03-510/20-25 25 mm Dia. 510/20nm BrightLine Single-Band Bandpass Filter by Semrock

Semrock's FF03-510/20-25 is a Bandpass Filter, specifically designed for applications requiring high transmission and blockage of unwanted light. This filter features a circular shape with a 25 mm diameter and a thickness of 2 mm, making it compatible with various optical systems.

The filter is designed to transmit light at a center wavelength (CWL) of 510 nm, with a full width at half maximum (FWHM) of 20 nm. The cut-on wavelength is 500 nm, and the cut-off wavelength is 520 nm, ensuring excellent blocking of out-of-band light. This specificity in wavelength transmission and blocking makes it ideal for applications where precise wavelength selection is crucial.

The FF03-510/20-25 is coated with Semrock's proprietary FF03-51020 coating on both the front and back surfaces, enhancing its performance and durability. The coating is designed to reduce surface reflections, thereby increasing transmission and minimizing scattering. This feature is particularly beneficial in applications where high signal-to-noise ratios are required.

The filter's shape is that of a Thin Lens, which is advantageous in systems where compactness and minimal optical aberrations are desired. This filter is currently in stock and available for immediate purchase through the provided weblink.
