27005 C 25 mm Dia. H-beta 5nm Bandpass Filter by Chroma
The 27005 C 25 mm Dia. H-beta 5nm Bandpass Filter is a high-quality optical component designed for precise wavelength selection, manufactured by Chroma. This filter is specifically designed for use with H-beta light sources, offering a narrow 5nm bandwidth for superior wavelength specificity.
The filter is circular in shape, with a diameter of 25mm and a thickness of 3.5mm, making it suitable for a wide range of optical applications. It features a UVFS MAL-1965 material ID, ensuring durability and reliability in various environments.
The physical data of the filter includes a cut-on wavelength of 482.5nm and a cut-off wavelength of 487.5nm, with a central wavelength (CWL) of 485nm. This precise wavelength control makes it ideal for applications requiring high spectral purity.
The filter is coated with Chroma's proprietary coatings on both the front and back surfaces, enhancing its performance and longevity. The coating type is not specified in the provided data, but it ensures minimal reflection and optimal transmission of the targeted wavelength.
The filter's shape is described as a thin lens, suggesting that it may have some degree of refractive power, although this is not explicitly stated in the provided data.
