400FIP5050 50 x 50 mm Precision IR Cut Filter 400-650nm

The 400FIP5050 is a precision IR cut filter, designed and manufactured by Knight Optical. This filter is specifically engineered to transmit light in the visible spectrum (400-650nm) while blocking infrared light, making it ideal for a wide range of applications where maintaining color accuracy and preventing thermal noise is crucial.

The filter is rectangular in shape, with dimensions of 50 x 50 mm, and a thickness of 1.1mm. It is made from high-quality N-BK7 Schott glass, a material known for its excellent optical properties and durability. The filter features a thin lens shape, which minimizes its impact on the overall optical path while providing optimal performance.

The 400FIP5050 filter boasts a cut-on wavelength of 400nm and a cut-off wavelength of 650nm, with a central wavelength (CWL) of 525nm. This specific wavelength transmission profile is achieved through the use of a precision bandpass coating on both the front and back surfaces of the filter. This coating is also manufactured by Knight Optical, ensuring consistent performance and compatibility with the base glass material.

The filter is currently in stock and available for immediate purchase through the Knight Optical website.
