400FIP1313 12.5 x 12.5 mm Precision IR Cut Filter 400-650nm

The 400FIP1313 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), making it ideal for applications that require the removal of infrared light.

The filter is constructed from high-quality N-BK7 Schott glass, a material known for its excellent optical properties and durability. It features a rectangular base shape, with dimensions of 12.5 x 12.5 mm and a thickness of 1.1 mm, providing a compact and robust design.

The 400FIP1313 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 range is achieved through the application of a specialized coating on both the front and back surfaces of the filter. The coating, also developed by Knight Optical, is denoted as 'kni 400fip'.

The filter's geometry and physical data make it suitable for a wide range of applications, including but not limited to, imaging systems, spectroscopy, and optical metrology. The 400FIP1313 is currently in stock and available for immediate purchase through the Knight Optical website.
