The 633DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 632.8nm. 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 633DIB25 is cut on at 627.8nm and cut off at 637.8nm, making it ideal for applications that require narrowband filtering around the 632.8nm wavelength.
The filter is made from UVFS Mal-1965, a material known for its optical properties. It has a circular base shape and a thickness of 6.1mm, which is suitable for most optical systems. The coating on both the front and back surfaces of the filter is KNI 633DIB, which enhances its performance and durability.
The 633DIB25 is available in a Thin Lens shape, making it compatible with various optical systems. According to the vendor, this item is currently in stock and more information can be found on their website.
