515DIB25 25 mm Dia. Standard Interference Bandpass Filter 514.5nm
The 515DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to center at a wavelength of 514.5nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking light outside this range. The 515DIB25 is cut on at 509.5nm and cut off at 519.5nm, ensuring a narrow and precise bandpass. The central wavelength (CWL) of the filter is 514.5nm, indicating the midpoint of this passband.
This filter is made from UVFS Mal-1965, a material known for its optical properties. It features a Thin Lens shape, which is beneficial for applications requiring minimal optical path deviation. The filter's geometry includes a diameter of 25mm and a thickness of 6.1mm, making it suitable for various optical systems.
The 515DIB25 is coated on both the front and back with KNI 515DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance, ensuring optimal transmission within the passband and minimal reflection.
