64-251 25 mm Dia. High Performance Laser Line Bandpass Filter; t=2mm 514.5nm

The 64-251 is a high-performance laser line bandpass filter, designed and manufactured by Edmund Optics. This filter, with a diameter of 25 mm, is specifically engineered for use with lasers emitting at a wavelength of 514.5 nm. The filter is constructed with a base shape of a circle, ensuring uniformity and consistency in its application.

The material used in the fabrication of this filter is N-BK7 Schott, a well-regarded optical glass known for its excellent optical properties. The filter has a thickness of 2 mm, providing sufficient structural integrity while minimizing optical distortions.

The coating on both the front and back of the filter is EDM 47-492. This coating is specifically designed to enhance the performance of the filter, ensuring high transmission at the desired wavelength and effective suppression of unwanted spectral components.

The filter's geometry is that of a thin lens, which not only aids in its integration into optical systems but also contributes to its high performance. The physical data of the filter includes a center wavelength (CWL) of 514.5 nm, further emphasizing its intended use with lasers of this wavelength.
