65-228 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 636nm

The 65-228 is a Bandpass Filter with a diameter of 50 mm, sourced from the reputable optical components vendor, Edmund Optics. This particular filter is designed to transmit light within a specific wavelength range, while blocking other wavelengths, making it ideal for applications that require wavelength selectivity.

The filter's central wavelength (CWL) is 636nm, which is the wavelength at which the filter has its maximum transmittance. The filter's passband, the range of wavelengths it allows to pass, is defined by its cut-on wavelength of 631nm and cut-off wavelength of 641nm. This 10nm bandpass is designed to provide a high level of transmission within this range, while effectively blocking light outside of it.

The filter is made from UVFS Mal-1965 material, and has a thickness of 3.5mm. It features hard coating on both the front and back surfaces, identified by the coating codes 'edm 65-106' for the front and the same for the back. This hard coating enhances the filter's durability and resistance to environmental factors, ensuring longevity and reliability in its performance.

The filter's circular shape and thin lens geometry make it compatible with a wide range of optical systems.
