The 670DIR25 is a 25 mm diameter Broadband Interference Bandpass Filter, specifically designed to center at 670nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. In this case, the 670DIR25 is designed to allow transmission of light between 650nm and 690nm, making it ideal for applications that require narrow-band light in the red spectrum.
The filter is made from UVFS MAL-1965, a material known for its optical properties in the visible light spectrum. It has a circular base shape, a common design for filters due to its ease of integration into various optical systems.
The 670DIR25 has a thickness of 6.1mm, providing sufficient structural integrity for handling and mounting. The front and back surfaces of the filter are coated with KNI 670DIR, a coating specifically designed to enhance the filter's performance.
The filter's geometry is defined by its 25mm diameter, making it suitable for use in systems with similar aperture sizes. It has a physical data of Cut On at 650nm and Cut Off at 690nm, with a Central Wavelength (CWL) of 670nm.
The filter's shape is classified as a Thin Lens, indicating that it may have lens-like properties. This could be beneficial in certain applications where the filter needs to focus or collimate light.
