Et440-40X R 26 mm x 38 mm Sputter Hard Coated; Bandpass Filter

The Et440-40X is a Bandpass Filter, designed and manufactured by Chroma, a renowned vendor in the optical industry. This filter is characterized by its rectangular base shape and thin lens design, making it a versatile component for various applications.

The filter's primary function is to allow light within a specific wavelength range to pass through while blocking light from other wavelengths. The Et440-40X is designed to pass light at a central wavelength (CWL) of 440 nanometers, with a cut-on wavelength of 420 nanometers and a cut-off wavelength of 460 nanometers. This makes it an ideal component for applications that require the precise filtering of light in the blue spectrum.

The filter is constructed with a width of 26 millimeters and a height of 38 millimeters, providing a substantial surface area for light interaction. It has a thickness of 1 millimeter, contributing to its robustness and durability. The front and back surfaces of the filter are coated with a sputter hard coating, identified as 'chr et440 40x'. This coating enhances the filter's performance and longevity, making it suitable for demanding optical environments.

The Et440-40X is currently in stock and available for purchase through the Chroma website. For more detailed information and specifications, please refer to the product page at https://www.chroma.com/products/parts/et440-40x.
