Et485-20X C 25 mm Dia. Sputter Hard Coated; Bandpass Filter

The Et485-20X is a Bandpass Filter, specifically designed and manufactured by Chroma, a leading vendor in the optical industry. This filter is part of the UVFS MAL-1965 material ID family, ensuring high-quality performance and reliability.

The filter is circular in shape, with a diameter of 25 mm and a thickness of 1 mm, making it a versatile component for various optical applications. The base shape is a Thin Lens, which is designed to minimize optical aberrations and distortions, thereby enhancing the overall optical system performance.

The Et485-20X Bandpass Filter is designed to operate at a central wavelength of 485 nm. It has a cut-on wavelength of 475 nm and a cut-off wavelength of 495 nm, providing a narrow bandwidth for specific optical filtering applications. The physical data of the filter, including the cut-on and cut-off wavelengths, are precisely controlled during the manufacturing process to ensure consistent performance.

The filter features a Sputter Hard Coating on both the front and back surfaces. This coating enhances the durability and scratch resistance of the filter, making it suitable for harsh environmental conditions. The coating also helps to reduce surface reflections, thereby improving the overall transmission of the filter.
