Ret266-3X R 26 mm x 38 mm Bandpass Filter by Chroma

The Ret266-3X R is a rectangular Bandpass Filter, measuring 26 mm in width and 38 mm in height, with a thickness of 1 mm. Manufactured by Chroma, this filter is designed for use in optical systems requiring precise wavelength control.

The filter's primary function is to allow light within a specific wavelength range to pass through while blocking light outside this range. In the case of the Ret266-3X R, this range is centered around 266 nm, with a cut-on wavelength of 264.5 nm and a cut-off wavelength of 267.5 nm. This makes it ideal for applications that require narrowband filtering around the ultraviolet region of the spectrum.

The Ret266-3X R features a coating on both the front and back surfaces, identified as 'chr ret266 3x'. This coating is designed to enhance the filter's performance, ensuring optimal transmission and blocking characteristics. The filter's shape is classified as a 'Thin Lens', suggesting it may have additional optical properties beyond simple wavelength filtering.
