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.

Company information
We import high-performance, advanced cutting-edge foreign products, mainly from the USA, France, Germany, Poland, and South Korea, and sell them to domestic universities, government agencies, and private companies. We also handle single-item import sales and OEM supply. UV (ultraviolet) LEDs and LED modules are used for sterilizing viruses and bacteria and are supplied as OEM products. We import optical components and detectors from VUV/UV to VIS, NIR, and IR. Black bodies (blackbody radiators) are used as references for thermometers. High-quality diamond powder/slurry from Quai Diamond Co. is used for polishing metals, ceramics, and more. We supply thermal imaging systems and night vision products from EO SYSTEM CO., LTD., which can detect objects in darkness, smoke, fog, dust, or camouflage. SWIR near-infrared InGaAs cameras are used for product quality control.
