89-764 27.5 mm Dia. Mounted Blue Machine Vision Imaging Filter; t=1.75 mm 470nm
The 89-764 is a circular Bandpass Filter, measuring 27.5 mm in diameter and 1.75 mm in thickness, designed for machine vision imaging applications. This filter is sourced from the reputable optical vendor, Edmund Optics, and is available for purchase through their website.
The filter is designed to transmit light within a specific wavelength range, centered at 470nm. The cut-on wavelength is 427.5nm, and the cut-off wavelength is 512.5nm, providing a narrow band of transmission. This characteristic makes it ideal for applications that require the isolation of specific wavelengths, such as fluorescence microscopy or other spectroscopic techniques.
The 89-764 filter is manufactured from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties and durability. The front and back surfaces of the filter are coated with EDM 89-764, a proprietary coating developed by Edmund Optics, further enhancing its performance and longevity.
The filter's geometry is designed in a Thin Lens shape, which is often used in optical systems to minimize aberrations and improve image quality. This feature makes the 89-764 an excellent choice for applications that require high-resolution imaging.
