89-839 45 mm Dia. Mounted IR Machine Vision Imaging Filter; t=1.75 mm 880nm
The 89-839 is a 45 mm diameter, 1.75 mm thick Bandpass Filter, specifically designed for machine vision imaging applications. Sourced from Edmund Optics, this filter features a catalog number of 89-839 and is available for purchase directly from their website.
This filter is designed to transmit light in the infrared (IR) spectrum, with a central wavelength (CWL) of 880 nanometers. The cut-on wavelength is 812.5 nanometers, and the cut-off wavelength is 947.5 nanometers, providing a narrow band of transmission. This makes it ideal for applications that require the isolation of specific wavelengths within the IR spectrum.
The 89-839 filter is coated with EDM 89-834 on both the front and back surfaces. This coating enhances the filter's performance and durability, ensuring reliable operation in demanding environments. The filter's thin lens shape allows for easy integration into optical systems, while its circular geometry provides consistent performance across the entire field of view.
