400FIP1515 15 x 15 mm Precision IR Cut Filter 400-650nm
The 400FIP1515 is a precision IR cut filter, designed and manufactured by Knight Optical. This filter is specifically engineered to block infrared light while allowing visible light to pass through. The filter has a catalog number of 400FIP1515 and is currently in stock, as indicated by its weblink status.
This rectangular filter is made from N-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. It measures 15 x 15 mm in width and length, with a thickness of 1.1 mm, making it a compact and versatile option for various optical applications.
The 400FIP1515 features a bandpass filter type, designed to transmit light within a specific range of wavelengths. The cut-on wavelength is 400nm, and the cut-off wavelength is 650nm, with a central wavelength (CWL) of 525nm. This means it allows light between 400nm and 650nm to pass through while blocking other wavelengths.
The filter is coated with KNI 400FIP on both the front and back surfaces, enhancing its performance and durability. The shape of the filter is thin lens, which is ideal for applications that require a flat, thin optical element.
