640HC10-25 25mm Dia. 640nm Borosilicate Glass Hard-Coated Narrowband Bandpass Filter, 10.0nm Bandwidth

The 640HC10-25 is a Hard-Coated Narrowband Bandpass Filter, designed and manufactured by Andover Corporation. This filter, with a catalog number 640HC10-25, is specifically engineered for applications requiring precise wavelength selection and high transmission. The filter is circular in shape, with a diameter of 25mm and a thickness of 5mm, making it compatible with a wide range of optical systems.

The filter's primary function is to allow light in a narrow band around the center wavelength of 640nm, while effectively blocking light at other wavelengths. The cut-on wavelength is 635nm, and the cut-off wavelength is 645nm, providing a tight 10.0nm bandwidth. This specificity makes it ideal for applications where narrowband filtering is crucial, such as fluorescence microscopy, spectroscopy, and other laser-based systems.

The 640HC10-25 filter features hard-coated surfaces on both the front and back, enhancing its durability and resistance to scratches and environmental factors. The coating also aids in maintaining high transmission and low autofluorescence, further improving the filter's performance.

The filter is currently in stock and available for immediate purchase through Andover Corporation's official website. For more information, please refer to the provided weblink.
