400FIP0505 5 x 5 mm Precision IR Cut Filter 400-650nm
The 400FIP0505 is a 5 x 5 mm Precision IR Cut Filter, specifically designed to transmit light in the 400-650nm range. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is a Bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking other wavelengths. In this case, the 400FIP0505 is designed to cut off light below 400nm and above 650nm, making it ideal for applications where precise wavelength control is necessary.
The filter is made of N-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low autofluorescence. The filter has a thickness of 1.1mm, providing durability and resistance to optical damage.
The 400FIP0505 features a Thin Lens shape, which is beneficial for applications where minimal optical distortion is required. The front and back of the filter are coated with KNI 400FIP, a proprietary coating developed by Knight Optical to enhance the filter's performance and durability.
According to the vendor's information, this filter has a cut-on wavelength of 400nm and a cut-off wavelength of 650nm, with a central wavelength (CWL) of 525nm. The filter is currently in stock and available for purchase through the vendor's website.
