89-838 42 mm Dia. Mounted IR Machine Vision Imaging Filter; t=1.75 mm 880nm
The 89-838 is a 42 mm diameter, 1.75 mm thick mounted IR machine vision imaging filter, specifically designed for use in the infrared spectrum with a central wavelength of 880nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.
The filter is a bandpass type, which means it allows light within a specific range of wavelengths to pass through while blocking out other wavelengths. In this case, the cut-on wavelength is 812.5nm, and the cut-off wavelength is 947.5nm. This makes the filter ideal for applications that require the use of specific infrared wavelengths.
The filter is coated with EDM 89-834 on both the front and back surfaces, which is a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance and durability, ensuring that it maintains its optical properties even under harsh conditions.
The filter's geometry is that of a thin lens, which is designed to minimize optical aberrations and distortions. This makes it suitable for use in high-precision imaging applications where optical quality is paramount.
