89-820 48 mm Dia. Mounted Light Red Machine Vision Imaging Filter; t=1.75 mm 633nm
The 89-820 is a Light Red Machine Vision Filter, specifically designed for imaging applications. Sourced from the renowned optical vendor, Edmund Optics, this filter boasts a circular shape with a diameter of 48 mm and a thickness of 1.75 mm. Its primary function is to allow light within a specific wavelength range to pass through while blocking other wavelengths, making it ideal for applications requiring precise light control.
The filter's central wavelength (CWL) is 633 nm, which is the wavelength at which it has its maximum transmittance. The cut-on wavelength is 598 nm, and the cut-off wavelength is 668 nm. This means that the filter starts to transmit light at 598 nm and stops transmitting at 668 nm, effectively isolating the 633 nm wavelength.
The 89-820 filter features a Base Shape of Circular and a Sub Type of Bandpass Filter. It is made from UVFS Mal-1965 material, ensuring durability and high-quality performance. The filter's coating, both on the front and back, is EDM 89-814, further enhancing its performance and longevity.
This filter is designed for use with Thin Lens optics and is currently in stock, as indicated by its weblink status. For more information, users can refer to the provided weblink or the vendor's catalog number.
