39-336 12.5 mm Dia. Hard Coated OD 4.0 5nm Bandpass Filter; t=3.5 mm 808nm
The 39-336 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow bandwidth transmission. Sourced from Edmund Optics, this filter features a circular shape with a diameter of 12.5 mm and a thickness of 3.5 mm, making it suitable for a wide range of applications.
The filter is constructed from UVFS Mal-1965 material, a common choice for its excellent optical properties. It is designed to transmit light at a central wavelength (CWL) of 808 nm, with a full width at half maximum (FWHM) of 5 nm. This precise wavelength selection is achieved through a hard coating on both the front and back surfaces, identified as EDM 39-336.
The cut-on wavelength is 805.5 nm, and the cut-off wavelength is 810.5 nm. This means that the filter begins transmitting light at 805.5 nm and stops transmitting at 810.5 nm, effectively isolating the desired wavelength.
The filter is shaped as a thin lens, which can be beneficial in certain optical configurations. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
