527FDC25 25 mm Dia. Bandpass Dichroic Filter 527nm

The 527FDC25 is a high-quality Dichroic Filter, boasting a 25 mm diameter and a thickness of 1.1 mm, sourced from the renowned optical component vendor, Knight Optical. This filter is designed to transmit light within a specific wavelength range while reflecting or blocking unwanted wavelengths, making it an essential component in various optical systems.

The filter's primary function is to pass light at a central wavelength of 527nm, with a specified range defined by a cut-on wavelength of 510nm and a cut-off wavelength of 545nm. This bandpass characteristic is crucial in applications where narrowband filtering is required, such as fluorescence microscopy, spectroscopy, and laser systems.

The 527FDC25 features a circular geometry, designed to fit into various optical setups with ease. It is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. This material ensures high transmission, low auto-fluorescence, and superior environmental stability.

The filter's coating is another notable feature. Both the front and back surfaces are coated with KNI 527FDC-0, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing surface reflections and improving transmission, thereby optimizing the overall system efficiency.
