The 89-770 is a 48 mm diameter mounted Blue Machine Vision Imaging Filter, with a thickness of 1.75 mm, specifically designed for use in the 470nm wavelength range. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their official website.
The filter is a Bandpass type, which means it allows light to pass through within a specific range of wavelengths while blocking out other wavelengths. In this case, the cut-on wavelength is 427.5nm, and the cut-off wavelength is 512.5nm, with the central wavelength at 470nm. This makes it ideal for applications that require precise filtering in the blue light spectrum.
The filter is made from UVFS Mal-1965 material, and it features a Thin Lens shape. The front and back of the filter are coated with EDM 89-764, a coating type that enhances the filter's performance and durability.
The 89-770 filter is currently in stock and can be ordered directly from the Edmund Optics website. With its specifications and features, this filter is an excellent choice for machine vision imaging applications that require precise filtering in the blue light spectrum.
