440FIB50 50 mm Dia. Standard Interference Bandpass Filter 440nm
The 440FIB50 is a 50 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 440nm wavelength range. 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 light to pass through a specific range of wavelengths while blocking out other wavelengths. This particular model has a cut-on wavelength of 435nm and a cut-off wavelength of 445nm, making it ideal for applications that require narrow-band light transmission around the 440nm range.
The 440FIB50 is made from UVFS Mal-1965, a material known for its excellent optical properties. It has a circular base shape and a thickness of 6.1mm, making it suitable for a wide range of optical systems. The filter's coating, KNI 440DIB, is applied to both the front and back surfaces, further enhancing its performance and durability.
This filter is available in a Thin Lens shape, which is beneficial for applications that require minimal optical path length distortion. The 440FIB50 is currently in stock and available for immediate purchase through the vendor's website.
