660DIR25 25 mm Dia. Broadband Interference Bandpass Filter 660nm
The 660DIR25 is a 25 mm diameter Broadband Interference Bandpass Filter, specifically designed to center at 660nm. 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 other wavelengths. In this case, the 660DIR25 is designed to allow transmission of light between 640nm and 680nm, 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. It has a circular base shape, a common design for filters due to its ease of integration into various optical systems. The filter's thickness is 6.1mm, providing sufficient structural integrity for most applications.
The 660DIR25 features a Thin Lens shape, which is beneficial for applications where minimal optical path deviation is required. The filter's coating is KNI 660DIR on both the front and back surfaces, enhancing its performance and durability.
According to the vendor's information, this filter is currently in stock and available for immediate purchase. For more detailed information, including pricing and availability, please refer to the vendor's website using the provided weblink.
