89-833 27.5 mm Dia. Mounted IR Machine Vision Imaging Filter; t=1.75 mm 880nm
The 89-833 is a circular Bandpass Filter, designed and manufactured by Edmund Optics, a leading vendor in the optical industry. This filter is specifically designed for use in machine vision imaging applications, featuring a 27.5 mm diameter and a thickness of 1.75 mm.
The filter's primary function is to allow light transmission within a specific wavelength range, while blocking other wavelengths. In this case, the 89-833 is designed to cut on at 812.5 nm and cut off at 947.5 nm, with a central wavelength (CWL) of 880 nm. This makes it ideal for applications that require the detection of light in the near-infrared spectrum.
The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It features a thin lens shape, which helps to minimize optical aberrations and distortions. The filter is coated on both the front and back with EDM 89-834, a coating that enhances its performance and durability.
According to the vendor's website, the 89-833 is currently in stock, and more information, including pricing and availability, can be found at the provided weblink. This filter is a reliable and high-performing option for any application that requires precise wavelength filtration in the near-infrared spectrum.
