750DIR25 25 mm Dia. Broadband Interference Bandpass Filter 750nm
The 750DIR25 is a 25 mm diameter Broadband Interference Bandpass Filter, specifically designed to center at 750nm. 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 cut-on wavelength is 730nm, and the cut-off wavelength is 770nm, making it ideal for applications that require narrow-band transmission around the 750nm region.
The 750DIR25 is made from UVFS MAL-1965, a material known for its optical properties and durability. It has a circular base shape and a thin lens shape, making it suitable for various optical systems. The filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing unwanted optical effects.
The filter's coating is KNI 750DIR on both the front and back surfaces. This coating enhances the filter's performance by ensuring high transmission within the passband and high rejection outside of it.
The filter is currently in stock and available for immediate purchase. For more information, you can visit the vendor's website through the provided weblink.
