LL01-266-12.5 12.5 mm Dia. 266nm MaxLinelaser clean-up Filter

The LL01-266-12.5 is a Bandpass Filter from Semrock, designed with a specific focus on clean-up applications for 266nm MaxLine lasers. This filter, with its circular shape and 12.5 mm diameter, is a versatile optical component, ideal for a wide range of applications.

The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties in the ultraviolet spectrum. It has a thickness of 2 mm, providing sufficient structural integrity while maintaining minimal optical impact.

The LL01-266-12.5 features a cut-on wavelength of 265.05 nm and a cut-off wavelength of 266.95 nm, with a central wavelength (CWL) of 266 nm. This precise wavelength specification ensures optimal performance in its intended application, effectively filtering out unwanted wavelengths and allowing the desired 266nm light to pass through.

The filter's coating is another critical aspect of its design. Both the front and back surfaces are coated with Sem LL01-266, a coating specifically designed to enhance the filter's performance in its intended application. This coating contributes to the filter's high transmission and excellent optical quality.

The filter's shape is described as a Thin Lens, indicating that it may have some lens-like properties, although this is not its primary function. This shape does not affect its performance as a Bandpass Filter but may influence how it interacts with other optical components in a system.
