Et555-25X C 25 mm Dia. Sputter Hard Coated; Bandpass Filter

The Et555-25X C 25 mm Dia. Sputter Hard Coated is a Bandpass Filter offered by Chroma, a leading vendor in the optical industry. This filter, with a catalog number of Et555-25X, is currently in stock and available for purchase through their official website.

The filter is of the Bandpass type, which means it allows a range of wavelengths to pass through while blocking others. The center wavelength (CWL) of this filter is 555 nm, making it ideal for applications that require precise filtering around this wavelength. The cut-on wavelength is 542.5 nm, and the cut-off wavelength is 567.5 nm, further emphasizing its narrow-band filtering capabilities.

This filter is circular in shape, with a diameter of 25 mm and a thickness of 1 mm. The circular shape is common in optical filters, providing uniformity and ease of integration into various optical systems. The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties.

The Et555-25X filter features a Thin Lens shape, which is often used in optical systems to minimize optical aberrations. The front and back of the filter are coated with chr et555 25x, a proprietary coating by Chroma that enhances the filter's performance and durability.
