Et520-40M C 25 mm Dia. Sputter Hard Coated; Bandpass Filter

The Et520-40M is a Bandpass Filter, sourced from the reputable vendor Chroma. This filter is specifically designed with a circular base shape and a diameter of 25 mm, making it suitable for a wide range of optical applications. The filter is characterized by its wavelength of 520 nm, which is a common choice for many optical systems.

The filter's physical data includes a cut-on wavelength of 500 nm and a cut-off wavelength of 540 nm, with a central wavelength (CWL) of 520 nm. This means that the filter allows transmission of light within this specific wavelength range, while blocking light outside of it. This feature is crucial in many optical systems where controlling the spectral bandwidth is essential.

The Et520-40M filter is fabricated with a Thin Lens shape, which is a common choice for many optical elements due to its minimal thickness and weight. The filter is also coated with a Sputter Hard Coating, specifically identified as 'chr et520 40m 5716' on both the front and back surfaces. This coating enhances the filter's durability and resistance to wear and tear, ensuring long-lasting performance.
