540DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 540nm
The 540DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to center at a wavelength of 540nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. In this case, the cut-on wavelength is 535nm, and the cut-off wavelength is 545nm, ensuring a narrow band of light centered at 540nm can pass through. This is particularly useful in applications where specific wavelength selection is required.
The filter is made from UVFS Mal- 1965, a material known for its optical properties. It has a thickness of 6.1mm, which is typical for this type of filter. The coating on both the front and back surfaces is KNI 540DIB, which is a proprietary coating from Knight Optical, designed to enhance the filter's performance.
The filter's shape is that of a Thin Lens, which is beneficial in applications where minimal optical distortion is required. This filter is currently in stock and available for immediate purchase through the vendor's website.
