880DIB25 25 mm Dia. Standard Interference Bandpass Filter 880nm
The 880DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 880nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. In this case, the cut-on wavelength is 875nm, and the cut-off wavelength is 885nm, providing a narrow bandwidth for optimal performance. The center wavelength (CWL) of the filter is 880nm, ensuring precise operation within the desired spectrum.
The 880DIB25 is made from UVFS Mal-1965, a material specifically chosen for its optical properties. The filter has a Thin Lens shape, which is beneficial for applications requiring minimal thickness and weight. The geometry of the filter includes a diameter of 25mm and a thickness of 6.1mm, making it suitable for various optical systems.
The filter's coating is KNI 880DIB, applied on both the front and back surfaces. This coating enhances the filter's performance and durability, ensuring reliable operation and longevity.
