27010 C 25 mm Dia. SII 5nm Bandpass Filter by Chroma

The 27010 C 25 mm Dia. SII 5nm Bandpass Filter is a high-quality optical component manufactured by Chroma, a leading vendor in the field of advanced optical solutions. This filter is specifically designed for applications that require precise wavelength selection and narrow bandwidth, making it an ideal choice for various research and industrial settings.

The filter features a circular shape with a diameter of 25 mm and a thickness of 3.5 mm, ensuring durability and stability during operation. It is made from UVFS-MAL 1965 material, which is known for its excellent optical properties and resistance to environmental factors. The filter's base shape is a Thin Lens, which is beneficial for applications where minimal optical path differences are crucial.

The 27010 C filter has a center wavelength (CWL) of 670 nm, which is the primary wavelength it allows to pass through. The cut-on wavelength is 667.5 nm, and the cut-off wavelength is 672.5 nm, creating a 5 nm bandpass. This narrow bandwidth is essential for applications that require high spectral resolution and rejection of unwanted wavelengths.

The front and back surfaces of the filter are coated with Chroma's proprietary coating (chr 27010), which enhances its performance by reducing surface reflections and improving transmission. This coating ensures optimal performance and longevity of the filter, making it a reliable choice for various applications.
