The 510DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light at a central wavelength of 510nm. 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 light to pass through a specific range of wavelengths while blocking out unwanted light from other parts of the spectrum. This is achieved through the use of a thin-film coating on both the front and back surfaces, designated as 'kni 510dib'. This coating is cut on at 505nm and cut off at 515nm, ensuring a tight bandpass around the desired 510nm wavelength.
The filter is made from UVFS Mal-1965, a material known for its excellent optical properties. It has a circular base shape and a thickness of 6.1mm, giving it a robust and durable construction. The geometry of the filter is defined by its diameter of 25mm, making it suitable for a wide range of optical applications.
The 510DIB25 is currently in stock and available for purchase through the Knight Optical website. For more information, please refer to the provided weblink.
