Custom Size BK7 Optical Filter

Product description

This fluorescence filter is designed for optimal performance in applications requiring precise spectral transmission. With a center wavelength of 692 nm and a full width at half maximum (FWHM) of 45 nm, it effectively transmits light while blocking unwanted wavelengths (OD6 from 200-900 nm). The filter is made from durable BK7 glass and features a hard-coat IAD-PVD process, ensuring longevity and reliability in various environments. Its customizable sizes and low minimum order quantity (MOQ) make it suitable for both prototyping and production needs.
