650DIR12 12.5 mm Dia. Broadband Interference Bandpass Filter 650nm
The 650DIR12 is a 12.5 mm diameter Broadband Interference Bandpass Filter, specifically designed for a central wavelength of 650nm. This filter is sourced from Knight Optical, a renowned 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 other wavelengths. The 650DIR12 is cut on at 630nm and cut off at 670nm, making it ideal for applications that require narrow-band light transmission around the 650nm wavelength.
The filter is made from UVFS Mal- 1965, a material known for its optical properties. It has a circular base shape and a thin lens shape, making it suitable for a wide range of optical systems. The filter's geometry includes a diameter of 12.5mm and a thickness of 6.1mm, providing a balance between compactness and durability.
The 650DIR12 features a KNI 650DIR coating on both the front and back surfaces, enhancing its optical performance and ensuring consistent light transmission. This filter is currently in stock and available for immediate purchase through the Knight Optical website.
