Using a set of 6 lenses with the same focal point at 2 wavelengths.
This is a two-wavelength laser beam expander designed for Galileo-style LIDAR optimized for high-output pulse lasers at wavelengths of 1064 and 532 nm. It accepts beams up to 10 mm in diameter (part number -10-) and expands them to 50 mm (part number 5X). All twelve surfaces are coated with high-performance anti-reflective coatings, with a reflectance specification of less than 0.25% per surface. The system is designed with theoretical wavefront performance of less than λ/10 at the design wavelength*. Mechanically, it measures approximately 22.5 cm in length, 6.6 cm in diameter, and 3.7 cm in height. It has a base that can be placed on an optical table, featuring two screw pitches. The hole closest to the cut surface of the base is for an M6 screw, and the other is for a ¼-20 screw.

basic information
Magnification: 5x Input: Effective diameter 10 mm Output: Effective diameter 50 mm Wavelength: 532 nm & 1064 nm Transmitted wavefront: <= λ/3 @ 632.8 nm Transmittance: > 95% Coating: All surfaces Double “V” AR for 532/1064 nm. 1064/532 R < 0.3% at 1064 nm; R < 0.6% at 532 nm per surface Damage threshold: 4 J/cm², 20 ns, 20 Hz at 1064 nm 6-element combined lens Housing: Length: Approximately 225 mm Diameter: 66 mm Base: The base has two screw pitches. The hole closest to the cut surface of the base is for an M6 screw, and the other is for a ¼-20 screw. These two-wavelength beam expanders have the same focal length at 1064 nm and 532 nm. Nd:YAG beams can be collimated at 1064 nm and 532 nm with the same lens spacing. They correct for spherical aberration at 1064 nm and 532 nm, and for coma aberration at 1064 nm.
