89-821 57 mm Dia. Mounted Light Red Machine Vision Imaging Filter; t=1.75 mm 633nm
The 89-821 is a Light Red Machine Vision Filter, specifically designed for imaging applications. Sourced from Edmund Optics, this filter boasts a circular shape with a diameter of 57 mm and a thickness of 1.75 mm, making it suitable for various optical systems.
The filter is a Bandpass Filter, which means it allows light within a specific range of wavelengths to pass through while blocking other wavelengths. In this case, the Central Wavelength (CWL) is 633 nm, indicating that it primarily transmits light in the red spectrum. The Cut-On wavelength is 598 nm, and the Cut-Off wavelength is 668 nm, further defining the range of transmitted light.
The 89-821 filter features a Thin Lens shape, implying that it has been designed to minimize optical aberrations. The front and back surfaces of the filter are coated with EDM 89-814, a coating type known for its durability and performance in machine vision applications.
This filter is currently in stock and can be purchased directly from the vendor through the provided web link. With its specifications and features, the 89-821 filter is an excellent choice for applications requiring red light filtration in machine vision imaging.
