Et645-75M R 26 mm x 38 mm Sputter Hard Coated; Bandpass Filter

The Et645-75M is a high-quality bandpass filter, designed and manufactured by Chroma, a leading vendor in the optical industry. This filter is specifically engineered for rectangular-shaped optical systems, with a base shape that measures 26 mm in width and 38 mm in height. The filter has a thickness of 1 mm, ensuring a compact and efficient design.

The Et645-75M filter is constructed with a unique material ID, referred to as "uvfs mal- 1965". This material is specifically chosen for its exceptional optical properties, ensuring high-performance and reliability. The filter is designed to operate at a central wavelength of 645 nm, making it ideal for applications that require precise wavelength control.

The physical data of the filter includes a cut-on wavelength of 607.5 nm and a cut-off wavelength of 682.5 nm. This means that the filter will only allow wavelengths between these two values to pass through, effectively blocking out unwanted light. The cut-on and cut-off wavelengths are carefully controlled during the manufacturing process, ensuring that the filter meets the stringent specifications required for high-precision optical applications.

The Et645-75M filter features a sputter hard coating on both the front and back surfaces. This coating enhances the durability and longevity of the filter, protecting it from scratches, abrasions, and other forms of damage. The coating also helps to reduce surface reflections, improving the overall efficiency and performance of the filter.

The filter's shape is classified as a Thin Lens, indicating that it has been designed to minimize optical aberrations and distortions. This makes it ideal for use in applications that require high-resolution, high-contrast imaging.
