538FDC12 12.5 mm Dia. Bandpass Dichroic Filter 538nm
The 538FDC12 is a high-quality Dichroic Filter, 12.5 mm in diameter, specifically designed for use at the 538nm wavelength. Sourced from the reputable optical components vendor, Knight Optical, this filter is a reliable choice for various applications.
This filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. The 538FDC12 is cut on at 512nm and cut off at 565nm, making it ideal for applications that require precise wavelength selection.
The filter is made from N-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. The filter's geometry includes a diameter of 12.5mm and a thickness of 1.1mm, ensuring robustness and durability.
The coating on both the front and back of the filter is KNI 538FDc-0, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance, ensuring high transmission at the desired wavelength and effective blocking of unwanted wavelengths.
The filter's shape is that of a Thin Lens, which can be beneficial in certain optical systems where minimal optical path deviation is required. The filter is currently in stock and available for immediate purchase through the Knight Optical website.
