650DIB25 25 mm Dia. Standard Interference Bandpass Filter 650nm
The 650DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 650nm wavelength range while blocking other wavelengths. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It has a base shape of a circle, a common choice for its ease of integration into various optical systems. The filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing unnecessary weight.
The 650DIB25 has a cut-on wavelength of 645nm and a cut-off wavelength of 655nm, meaning it begins transmitting light at 645nm and stops transmitting at 655nm. The central wavelength (CWL) of this filter is 650nm, the wavelength at which the filter's transmission is at its maximum.
Both the front and back surfaces of the filter are coated with KNI 650DIB, a coating that enhances the filter's performance and durability. The filter's shape is described as a Thin Lens, indicating its potential use in focusing or collimating light.
