550DIB25 25 mm Dia. Standard Interference Bandpass Filter 550nm
The 550DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to center at 550nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking out unwanted light from outside this range. The 550DIB25 is cut on at 545nm and cut off at 555nm, ensuring a tight and precise bandpass. The central wavelength (CWL) of the filter is 550nm, indicating that this is the wavelength at which the filter has its maximum transmission.
The filter is made from UVFS Mal-1965, a material known for its excellent optical properties. It has a circular base shape, a common and versatile form factor for optical elements. The filter's geometry includes a diameter of 25mm and a thickness of 6.1mm, making it suitable for a wide range of applications.
The 550DIB25 features a KNI 550DIB coating on both the front and back surfaces. This coating is specifically designed for this filter, enhancing its performance and durability. The filter's shape is thin lens, a design that minimizes optical aberrations and ensures high-quality performance.
