400FIP0015 15 mm Dia. Precision IR Cut Filter 400-650nm
The 400FIP0015 is a high-precision bandpass filter, specifically designed to transmit light in the 400-650nm wavelength range while blocking infrared (IR) light. This filter is sourced from Knight Optical, a reputable vendor known for their quality optical components.
The filter is circular in shape, with a diameter of 15mm and a thickness of 1.1mm, making it suitable for a wide range of optical applications. It is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high damage threshold.
The 400FIP0015 features a cut-on wavelength of 400nm and a cut-off wavelength of 650nm, with a central wavelength (CWL) of 525nm. This means it allows light in the blue to orange spectrum to pass through while blocking unwanted IR light. The coating on both the front and back surfaces of the filter is KNI 400FIP, which contributes to its high transmission and excellent blocking capabilities.
The filter is designed in a thin lens shape, which can be beneficial in certain optical systems where space is limited. It is currently in stock and available for immediate purchase through the vendor's website.
