520HC10-25 25mm Dia. 520nm Borosilicate Glass Hard-Coated Narrowband Bandpass Filter, 10.0nm Bandwidth

The 520HC10-25 is a Hard-Coated Narrowband Bandpass Filter, designed and manufactured by Andover Corporation. This filter is specifically engineered for applications requiring precise wavelength selection and narrow bandwidths. The filter boasts a center wavelength of 520nm, with a 10.0nm bandwidth, making it ideal for applications that demand high spectral resolution and rejection of out-of-band light.

The filter is constructed from borofloat33, a type of borosilicate glass known for its excellent optical properties and durability. The circular shape of the filter has a diameter of 25mm and a thickness of 5mm, ensuring robustness and ease of integration into various optical systems.

The 520HC10-25 filter features hard coatings on both the front and back surfaces. These coatings enhance the filter's durability and resistance to environmental factors, ensuring long-term performance and reliability. The coating also provides superior optical performance, with high transmission and low scatter, contributing to the overall efficiency and quality of the optical system.

The filter's physical data includes a cut-on wavelength of 515nm and a cut-off wavelength of 525nm. This wavelength range is achieved through precise manufacturing processes, ensuring the filter's high spectral purity and selectivity.
