Et520-20M C 25 mm Dia. Bandpass Filter by Chroma

The Et520-20M is a Bandpass Filter with a circular base shape, designed and manufactured by Chroma. This filter is part of the UVFS MAL-1965 material ID family, ensuring high-quality performance and durability.

The filter's primary function is to allow light transmission within a specific range of wavelengths while blocking light outside this range. The Et520-20M is designed to pass wavelengths around 520 nanometers, making it ideal for applications that require precise light filtration at this wavelength.

The filter has a diameter of 25 millimeters and a thickness of 1 millimeter, making it compact and easy to integrate into various optical systems. The cut-on wavelength is 510 nanometers, and the cut-off wavelength is 530 nanometers, providing a narrow bandwidth for optimal light filtration. The center wavelength (CWL) is 520 nanometers, ensuring accurate light transmission at this wavelength.

The Et520-20M features a thin lens shape and is coated on both the front and back with Chroma's proprietary coating (chr et520 20m), enhancing its light transmission and blocking capabilities. The filter's weblink status is valid and in stock, ensuring quick and easy acquisition for your optical projects.
