65-732 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 400nm

The 65-732 is a 12.5 mm diameter mounted traditional coated bandpass interference filter, with a thickness of 7.5 mm, specifically designed for 400nm wavelength applications. This filter is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.

The filter is a Bandpass type, which means it allows light to pass within a certain range of wavelengths while blocking other wavelengths. This specific model is designed to pass wavelengths around 400nm, making it ideal for applications that require precise filtering in the ultraviolet spectrum.

The filter's geometry includes a 12.5 mm diameter, providing a substantial surface area for light to pass through, and a thickness of 7.5 mm, which contributes to its overall durability and stability. The physical data of the filter indicates a cut-on wavelength of 375nm and a cut-off wavelength of 425nm, further emphasizing its specificity for 400nm applications.

The coating of the filter is a crucial aspect of its functionality. Both the front and back surfaces of the filter are coated with the EDM 65-732 coating, which is specifically designed to enhance the filter's performance and durability.

The filter's shape is described as a Thin Lens, which suggests that it is designed to minimize optical aberrations and distortions, thereby ensuring optimal light transmission and image quality. This feature makes the filter particularly suitable for applications that require high-precision optical performance.
