The 440FWP7575 is a 75 x 75 mm Bandpass Wratten Colour Filter, specifically designed to pass light in the 440nm wavelength range. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.

The filter is a Bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking out other wavelengths. This is particularly useful in applications where a narrow range of wavelengths needs to be isolated or emphasized. The 440FWP7575 has a cut-on wavelength of 414nm and a cut-off wavelength of 480nm, with a central wavelength (CWL) of 447nm.

The filter is made from UVFS Mal-1965 material, a durable and reliable option for optical filters. It has a rectangular base shape and a thin lens shape, making it suitable for a wide range of applications. The filter's geometry includes a width of 75mm, a length of 75mm, and a thickness of 0.1mm.

The 440FWP7575 is coated with KNI 440FWP on both the front and back, which enhances its performance and durability. This filter is currently in stock and available for purchase on Knight Optical's website. For more information, you can visit the provided weblink.
