620FIB12 12.5 mm Dia. Standard Interference Bandpass Filter 620nm
The 620FIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 620nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking out unwanted light from other spectral regions. The cut-on wavelength is 615nm, and the cut-off wavelength is 625nm, providing a narrow bandwidth for precise optical applications.
The 620FIB12 is made from UVFS MAL-1965, a material known for its excellent optical properties. The filter has a thickness of 6.1mm, which is suitable for most optical systems. The coating on both the front and back surfaces of the filter is KNI 620DIB, which enhances its performance in specific wavelength ranges.
The filter's geometry is that of a Thin Lens, making it suitable for use in various optical systems where minimal thickness and weight are desirable. The physical data of the filter, such as the central wavelength and bandwidth, are carefully controlled during manufacturing to ensure consistent performance.
This filter is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
