700DIR25 25 mm Dia. Broadband Interference Bandpass Filter 700nm
The 700DIR25 is a 25 mm diameter Broadband Interference Bandpass Filter, specifically designed for a central wavelength of 700nm. 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. In this case, the 700DIR25 is designed to allow transmission of light between 680nm and 720nm, 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 choice for its ease of integration into various optical systems.
The 700DIR25 has a thickness of 6.1mm, providing sufficient structural integrity for most applications. The front and back surfaces of the filter are coated with KNI 700DIR, a coating specifically designed to enhance the filter's performance.
The filter's geometry is that of a Thin Lens, which can be beneficial in certain optical system designs. The filter is currently in stock and available for immediate purchase through the vendor's website.
