589HC10-12.5 12.5mm Dia. 589nm Borosilicate Glass Hard-Coated Narrowband Bandpass Filter, 10.0nm Bandwidth

The 589HC10-12.5 is a high-quality Bandpass Filter, offered by the renowned optical components manufacturer, Andover Corporation. This filter is designed with a circular shape, featuring a diameter of 12.5mm and a thickness of 5mm, making it suitable for a wide range of optical applications.

The filter is made of borofloat33, a type of borosilicate glass known for its excellent optical properties, including high transparency and low autofluorescence. This material also offers superior chemical resistance and mechanical strength, ensuring the filter's durability and longevity.

The 589HC10-12.5 is specifically designed for use at a central wavelength of 589nm, with a bandwidth of 10.0nm. The cut-on wavelength is 584nm, and the cut-off wavelength is 594nm. This narrow bandwidth ensures high spectral selectivity, making the filter ideal for applications that require precise wavelength control, such as fluorescence microscopy, spectroscopy, and laser technology.

The filter features hard-coated anti-reflection (AR) coatings on both the front and back surfaces. These coatings, designated as 'and 589hc10', are designed to minimize surface reflections and increase transmission, thereby enhancing the filter's performance and reliability. The 'Thin Lens' shape of the filter further contributes to its high performance by reducing optical aberrations.
