720FIB12 12.5 mm Dia. Standard Interference Bandpass Filter 720nm
The 720FIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 720nm. 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 wavelengths. The cut-on wavelength is 715nm, and the cut-off wavelength is 725nm, providing a narrow bandwidth for optimal performance. The center wavelength (CWL) of the filter is, as mentioned, 720nm.
The filter is made from UVFS Mal-1965, a material known for its optical properties and durability. It features a Thin Lens shape, which is beneficial for applications where space is a constraint. The filter has a thickness of 6.1mm, providing sufficient structural integrity while minimizing unnecessary bulk.
The coating on both the front and back of the filter is KNI 720DIB. This coating is specifically designed to enhance the filter's performance, ensuring efficient light transmission within the desired wavelength range.
The filter is currently in stock and available for immediate purchase. For more information, you can visit the vendor's website through the provided weblink.
