89-835 32.5 mm Dia. Mounted IR Machine Vision Imaging Filter; t=1.75 mm 880nm

The 89-835 is a mounted IR machine vision imaging filter, specifically designed for applications requiring a bandpass filter with a center wavelength of 880nm. This filter is sourced from the reputable optical vendor, Edmund Optics, and boasts a catalog number of 89-835.

The filter is circular in shape, with a diameter of 32.5mm and a thickness of 1.75mm, making it suitable for a wide range of optical systems. The base shape is a Thin Lens, which is known for its minimal thickness and light weight, making it an ideal choice for applications where space and weight are critical factors.

The 89-835 features a UV-VIS cut-off M305 x 050 machine vision filter, which is designed to block ultraviolet and visible light while allowing infrared light to pass through. The cut-on wavelength is 812.5nm, and the cut-off wavelength is 947.5nm, ensuring a tight bandpass around the desired 880nm wavelength.

The filter is coated with EDM 89-834 on both the front and back surfaces, providing excellent durability and resistance to environmental factors. This coating also enhances the filter's performance, ensuring optimal light transmission and blocking unwanted wavelengths.

The filter's weblink status is valid and in stock, indicating its availability for immediate use. For more information, users can visit the provided weblink: https://www.edmundoptics.com/p/uv-vis-cut-off-m305-x-050-machine-vision-filter/32273/.
