89-767 37 mm Dia. Mounted Blue Machine Vision Imaging Filter; t=1.75 mm 470nm

The 89-767 is a circular Bandpass Filter, designed and manufactured by Edmund Optics, specifically for machine vision imaging applications. This filter features a 37 mm diameter and a thickness of 1.75 mm, making it suitable for various optical systems. The filter's primary function is to allow light within a specific wavelength range to pass through while blocking other wavelengths, enhancing image quality and accuracy.

The 89-767 filter is designed to pass light at a central wavelength (CWL) of 470nm, which falls within the blue light spectrum. This property makes it ideal for applications that require the detection and analysis of blue light, such as fluorescence microscopy, machine vision, and other scientific research.

The filter's physical data includes a cut-on wavelength of 427.5nm and a cut-off wavelength of 512.5nm. This means that it begins to transmit light at 427.5nm and stops transmitting at 512.5nm, effectively filtering out unwanted wavelengths.

The filter is coated with EDM 89-764 on both the front and back surfaces, enhancing its performance and durability. The shape of the filter is thin lens, which is designed to minimize optical aberrations and distortions.
