1064HC10-25 25mm Dia. 1064nm Borosilicate Glass Hard-Coated Narrowband Bandpass Filter, 10.0nm Bandwidth

The 1064HC10-25 is a Hard-Coated Narrowband Bandpass Filter, designed and manufactured by Andover Corporation. This filter is specifically engineered for use in optical systems that require precise wavelength selection and high transmission. The filter's primary function is to allow light in a narrow band around the central wavelength of 1064nm, while effectively blocking light at other wavelengths.

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. It is constructed from borofloat33, a type of borosilicate glass known for its excellent optical properties and durability.

The 1064HC10-25 has a cut-on wavelength of 1059nm and a cut-off wavelength of 1069nm, resulting in a bandwidth of 10.0nm. This narrow bandwidth ensures high spectral purity and low background noise, which is crucial in many applications such as laser spectroscopy, bio-imaging, and fluorescence microscopy.

The filter's coating is another key feature. Both the front and back surfaces of the filter are hard-coated with Andover's proprietary 1064hc10 coating. This coating enhances the filter's performance by increasing its damage threshold and environmental stability, making it suitable for use in harsh environments.

In terms of geometry, the filter is shaped as a thin lens, which can be beneficial in certain optical system designs. The filter is currently in stock and available for immediate purchase through Andover Corporation's website.
