Et550-20X C 25 mm Dia. Bandpass Filter by Chroma

The Et550-20X C 25 mm Dia. 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 within the visible spectrum.

The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking light outside this range. The central wavelength (CWL) of this filter is 550nm, making it ideal for applications that require light in the green region of the spectrum. The filter's passband, defined by the cut-on wavelength of 540nm and the cut-off wavelength of 560nm, ensures a narrow and precise transmission band.

This filter is circular in shape, with a diameter of 25mm and a thickness of 1mm, making it compatible with various optical systems. The filter's coating, identified as "chr et550 20x" on both the front and back surfaces, enhances its performance and durability. The coating also reduces reflection and increases transmission, ensuring optimal light propagation through the filter.

The Et550-20X filter features a Thin Lens shape, which implies that it has been designed to minimize optical aberrations and distortions. This feature is particularly beneficial in applications that require high-resolution imaging or precise wavelength discrimination.
