86-957 25 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 825nm

The 86-957 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow bandwidth transmission. This filter, sourced from Edmund Optics, features a 25 mm diameter and a thickness of 3.5 mm, making it suitable for a wide range of applications.

The filter's primary function is to transmit light within a specific range of wavelengths while blocking light outside this range. The 86-957 is designed to transmit light at a central wavelength (CWL) of 825nm, with a cut-on wavelength of 800nm and a cut-off wavelength of 850nm. This precise wavelength selection is crucial in many optical systems, such as spectroscopy, fluorescence microscopy, and laser applications.

The filter is made from UVFS Mal-1965 material, a common choice for its excellent optical properties and durability. The front and back surfaces of the filter are coated with EDM 86-945, a hard coating that enhances the filter's resistance to scratches and environmental damage, ensuring longevity and reliability in operation.

The 86-957 filter is shaped as a Thin Lens, a design that minimizes optical aberrations and distortions, contributing to the overall performance of the optical system. The filter is currently in stock and available for immediate use. For more information, please refer to the provided weblink.
