The 89-816 is a Light Red Machine Vision Imaging Filter, specifically designed for use in machine vision applications. Sourced from the reputable vendor Edmund Optics, this filter boasts a catalog number of 89-816 and is readily available for purchase.
This filter is a Bandpass Filter, a type that allows only a specific range of wavelengths to pass through while blocking others. The 89-816 is designed to permit light with a wavelength of 633nm, making it ideal for applications that require precise wavelength selection.
The filter is circular in shape, with a diameter of 36mm, providing a substantial surface area for light to pass through. It has a thickness of 1.75mm, ensuring durability and rigidity. The material used for this filter is UVFS Mal- 1965, a choice that enhances its performance in specific applications.
The 89-816 features a Cut On wavelength of 598nm and a Cut Off wavelength of 668nm. This means that it begins to transmit light at 598nm and stops transmitting at 668nm, effectively filtering out any wavelengths outside this range. The Central Wavelength (CWL) of this filter is 633nm, the point at which it transmits light most efficiently.
Both the front and back of this filter are coated with EDm 89-814, a coating that enhances its performance and durability. The filter's shape is Thin Lens, a design that minimizes optical aberrations and distortions, ensuring clear and accurate imaging.
