86-963 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 525nm

The 86-963 is a Bandpass Filter, specifically designed with a 525nm central wavelength (CWL), sourced from Edmund Optics. This filter is circular in shape, with a diameter of 50 mm and a thickness of 3.5 mm, making it suitable for a wide range of optical applications.

The filter is made from UVFS MAL-1965 material, a common choice for its excellent optical properties. It is designed to pass light within the 50nm band centered around 525nm, while effectively blocking light outside this range. This is achieved through the use of hard coatings on both the front and back surfaces, specifically the EDM 86-939 coating.

The physical data of the filter is also noteworthy. It has a cut-on wavelength of 500nm and a cut-off wavelength of 550nm, providing a narrow and precise band of passable light. This makes it ideal for applications that require high spectral purity and precise wavelength selection.

The filter is available in a Thin Lens shape, which is often preferred for its minimal impact on the overall optical path length. The catalog number for this item is 86-963, and it can be found on the Edmund Optics website, where it is currently in stock.
