780DIJ12 12.5 mm Dia. Standard Interference Bandpass Filter 780nm
The 780DIJ12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to center at 780nm. 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 775nm, and the cut-off wavelength is 785nm, making it highly effective in isolating the 780nm wavelength. The Central Wavelength (CWL) of the filter is also 780nm, ensuring optimal performance for its intended use.
The filter is made from UVFS Mal- 1965, a material known for its excellent optical properties. It has a Thin Lens shape, which is beneficial for applications that require minimal optical path deviation. The filter's geometry includes a diameter of 12.5mm and a thickness of 6.1mm, making it suitable for various optical systems.
The coating on both the front and back of the filter is KNI 780DIJ. This coating is designed to enhance the filter's performance and durability, ensuring reliable and consistent operation.
