89-834 27.5 mm Dia. Mounted IR Machine Vision Imaging Filter; t=1.75 mm 880nm

The 89-834 is a circular filter, 27.5 mm in diameter and 1.75 mm in thickness, designed for use in machine vision imaging applications. This filter is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components.

The filter is a bandpass type, specifically designed to allow light in the 880 nm wavelength range to pass through while blocking other wavelengths. The cut-on wavelength is 812.5 nm, and the cut-off wavelength is 947.5 nm, providing a narrow passband around the desired 880 nm wavelength. This makes it ideal for applications that require precise wavelength selection.

The 89-834 filter features a UV-VIS cut-off M255 x 0.50 imaging filter with the material ID UVFS Mal-1965. The front and back of the filter are coated with EDm 89-834, providing excellent durability and resistance to environmental factors.

The filter's shape is described as thin lens, suggesting it may have some light bending properties. However, this should be confirmed with the vendor or through further investigation.

The filter is currently in stock and can be purchased directly from the vendor through the provided weblink. With its high-quality construction, precise wavelength selection, and versatile thin lens shape, the 89-834 is an excellent choice for any machine vision imaging application requiring a narrow bandpass filter in the 880 nm range.
