Laser collimation and beam expansion system

MG-Optics develops one 300mm Laser collimation and beam expansion system. From the optical and structure design, the primary mirror assemly design, mirrors fabrication and optical alignment to the the whole optical system  delivery, we use only 6 months.   SPECIFICATION Wavelength 1064nm Entrance pupil diameter 300mm Exit pupil diameter 4mm Magnification 75× Field of view ±200urad Total length 1099mm Diameter φ400mm The whole optical system Exit Pupil wavefront error full aperture RMS is better thanλ/10(λ=633nm); ±30μrad RMS better than λ/15(λ=633nm) Primary mirror: Off Axis Parabolic Mirror Secondary mirror:Hyperboloid mirror M3:freeform mirror M4:flat mirror The optical and structure design diagram   The primary mirror surface accuracy test  MG-Optics is bringing new and novel optics solutions, especially complex optical system.
