This is a 980HC10-12.5 Hard-Coated Narrowband Bandpass Filter, a high-quality optical component designed for precise wavelength selection. The filter is manufactured by Andover Corporation, a renowned vendor in the optical industry.
The filter is of the Bandpass type, specifically designed to allow light within a narrow range of wavelengths to pass through while blocking out other wavelengths. This particular model is centered at 980nm, with a bandwidth of 10.0nm, making it ideal for applications that require narrowband filtering around this wavelength.
The filter is made from borofloat33, a type of borosilicate glass known for its excellent optical properties and durability. It has a circular shape with a diameter of 12.5mm and a thickness of 5mm, making it compatible with a wide range of optical systems.
The filter's coating is another notable feature. Both the front and back surfaces are hard-coated with the Andover Corporation's 980HC10 coating, which enhances the filter's performance and durability. This coating helps to reduce surface reflections and increase transmission, making the filter more efficient.
The filter's physical data includes a cut-on wavelength of 975nm and a cut-off wavelength of 985nm, ensuring that only light within the desired wavelength range is transmitted. The center wavelength (CWL) is 980nm, which is the wavelength at which the filter has its highest transmission.
In terms of shape, this filter is a Thin Lens, which means it has been designed to minimize optical aberrations and distortions. This makes it suitable for use in high-precision optical systems.
The filter is currently in stock and can be purchased directly from the Andover Corporation's website.
