505FDC12 12.5 mm Dia. Bandpass Dichroic Filter 505nm

The 505FDC12 is a high-quality Dichroic Filter, 12.5 mm in diameter, designed for use in optical systems that require precise wavelength selection around the 505nm range. Sourced from Knight Optical, a renowned vendor in the optical industry, this filter is a reliable choice for various applications.

The filter is a Bandpass type, meaning it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. The cut-on wavelength is 485nm, and the cut-off wavelength is 525nm, providing a narrow, precise band of transmission. This makes it ideal for applications that require strict wavelength control, such as fluorescence microscopy, spectroscopy, and laser systems.

The filter is made from N-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties and durability. The filter's geometry includes a diameter of 12.5mm and a thickness of 1.1mm, ensuring efficient light transmission and minimal optical distortion.

The coating on both the front and back surfaces of the filter is KNI 505FDC-0, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by ensuring high transmission within the passband and low reflection at the edges of the passband.

The filter's shape is a Thin Lens, which means it can be used in optical systems that require focusing or collimating light. This versatile shape adds to the filter's functionality, making it a valuable component in various optical setups.
