520FCS2500 25 mm Dia. Colour Glass Bandpass Filter 515nm

The 520FCS2500 is a 25 mm diameter Color Glass Bandpass Filter, specifically designed with a central wavelength of 515nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The filter is of the Sub Type 'Color Glass' and has a base shape of 'Circular'. It is made from the material identified as 'uvfs mal- 1965', and has a thickness of 3mm. The geometry of the filter is designed to provide precise optical performance, with a diameter of 25mm, ensuring a good balance between size and functionality.

The 520FCS2500 features physical data that includes a cut-on wavelength of 415nm and a cut-off wavelength of 575nm. The central wavelength (cwl) is 515nm, which is the primary wavelength that this filter is designed to transmit. This makes it ideal for applications that require the selective transmission of light in the yellow-green region of the spectrum.

The filter is coated with 'kni 420fcs' on both the front and back surfaces, which is likely a proprietary coating developed by Knight Optical. This coating enhances the filter's performance and durability, ensuring reliable operation in various environments.

The shape of the filter is 'Thin Lens', indicating that it has been designed to minimize optical aberrations and distortions. This is particularly important in applications that require high-precision optical performance.
