Et697-60M C 25 mm Dia. Bandpass Filter by Chroma

The Et697-60M is a Bandpass Filter with a circular base shape, designed and manufactured by Chroma. This filter is specifically engineered for use in optical systems and applications where precise wavelength selection and transmission are crucial.

The filter has a diameter of 25 mm and a thickness of 1 mm, making it a compact yet highly effective component. It is designed to transmit light within a specific wavelength range, blocking out unwanted wavelengths on either side of this range. The cut-on wavelength is 667, and the cut-off wavelength is 727, with the central wavelength (CWL) at 697. This means the filter allows light transmission between these wavelengths, making it ideal for applications that require this specific wavelength selection.

The Et697-60M features a coating on both the front and back surfaces, identified as 'chr et697 60m'. This coating enhances the filter's performance and durability, ensuring reliable and consistent operation in various conditions.

The filter is designed in the shape of a thin lens, which is a common form factor for many optical components. This design allows for easy integration into existing optical systems or new setups.
