650HC10-25 25mm Dia. 650nm Borosilicate Glass Hard-Coated Narrowband Bandpass Filter, 10.0nm Bandwidth

The 650HC10-25 is a high-performance Bandpass Filter, designed and manufactured by Andover Corporation. This filter is specifically engineered for applications requiring narrowband transmission at 650nm, with a bandwidth of 10.0nm.

The filter is constructed from borofloat33, a high-quality borosilicate glass, known for its excellent optical properties and durability. The circular shape of the filter has a diameter of 25mm, making it compatible with a wide range of optical systems. The filter's thickness is 5mm, providing robustness and stability during operation.

The 650HC10-25 features hard-coated surfaces on both the front and back, enhancing its durability and resistance to environmental factors such as dust, moisture, and scratches. The cut-on wavelength is 645nm, and the cut-off wavelength is 655nm, ensuring a narrowband transmission at the desired wavelength. The central wavelength (CWL) is 650nm, indicating the center of the transmission curve.

The filter's shape is that of a Thin Lens, which can be beneficial in certain optical configurations. The Andover Corporation's 650HC10-25 is currently in stock and available for immediate purchase through their website.
