65-108 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 647nm

The 65-108 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for use with a central wavelength of 647nm, making it ideal for applications that require precise wavelength selection.

The filter is constructed with a hard coating on both the front and back surfaces, denoted as 'edm 65-108'. This coating enhances the filter's durability, making it resistant to wear and tear, a crucial factor for components subjected to frequent handling or harsh environments.

The physical data of the filter indicates a cut-on wavelength of 642nm and a cut-off wavelength of 652nm. This 10nm bandpass, situated between the cut-on and cut-off wavelengths, is where the filter allows maximum transmission, providing a narrow, precise band of wavelengths for your optical system.

The filter's geometry includes a thickness of 3.5 mm, which contributes to its overall optical performance and mechanical stability. The Base Shape is circular, and the Material ID is UVFS MAL-1965.

The filter is available in a Thin Lens shape, which is beneficial for applications where space is a constraint or for systems that require minimal optical path length distortion.
