FGB37H 6 in x 6 in Square BG40 Colored Glass Bandpass Filter; 335-610nm

The FGB37H is a 6 in x 6 in Square BG40 Colored Glass Bandpass Filter, designed and manufactured by Thorlabs. This filter is specifically engineered for use within the wavelength range of 355nm, making it an ideal component for applications that require precise filtering within this spectrum.

The filter is constructed from high-quality n-bk7 Schott glass, a material known for its excellent optical properties and durability. It features a rectangular base shape, with a width and height of approximately 152.4mm each, and a thickness of 3mm. This robust construction ensures the filter can withstand the rigors of regular use while maintaining its optical performance.

The FGB37H boasts a cut-on wavelength of 335nm and a cut-off wavelength of 610nm, providing a precise bandpass filtering capability. This is further enhanced by the front and back coatings of 'tho fgb37', which are specifically designed to optimize the filter's performance within its specified wavelength range.

The filter's shape is classified as a Thin Lens, indicating its potential use in lens systems. This versatile component is currently in stock and available for immediate purchase through the Thorlabs website, as indicated by its weblink status.
