The application of off-axis parabolic mirrors in astronomical telescopes
The main optical properties of a parabolic mirror：it can reflect light rays emitted from its focus into a parallel beam, or reflect a parallel beam of light and focus it at a point. This is because the geometric properties of a parabola determine that light rays starting from the focus will be parallel to the axis of symmetry of the parabola after reflection, and conversely, light rays parallel to the axis of symmetry will converge at the focus after reflection. Structure and DesignA parabolic...
large aspherical mirror testing with CGH and auxiliary lenses
At present, the radius of curvature of the primary mirror in some large-aperture optical telescopes has reached the order of tens of meters. If the surface of the mirror is tested simply by CGH, the length of the testing optical path is not lower than the length of its radius of curvature. Due to factors such as site size and ambient airflow disturbance, it is difficult to achieve high-precision measurement of the mirror surface under these conditions. In order to solve the problem of...
Definition of Optical Freeform Surfaces Common optical surfaces include planes, spherical surfaces, rotationally symmetrical aspheric surfaces, and cylindrical surfaces. These types of surfaces do not fall under the category of freeform surfaces. According to the definition of freeform surfaces, a freeform surface is one that does not possess axial rotational symmetry or translational symmetry constraints. Therefore, one significant characteristic of freeform surfaces is their asymmetry; they...
Manufactureing of 720mm SiC Aspherical Mirror
1.Milling process: the back-side milling of the mirror can be achieved on a general three-axis CNC machining center, while the mirror surface milling requires a four-axis or even five-axis machining center. If a high-precision five-axis machining center is used and appropriate grinding tools are selected, the mirror surface milling accuracy within one meter diameter can reach 10um. 2.Grinding process: grinding mainly removes the tool traces and subsurface damage layer left by milling, and...
How to use CGH to do the test of aspheric mirrors?
CGH stands for Computer Generated Hologram. It is an optical element that is used in interferometric measurement of complex surfaces, such as aspheric optics or freeform optics. CGH is designed using computer algorithms and then manufactured via optical lithography. The holographic interference fringes contained within the CGH element can generate an exact replica of the intended wavefront it is designed to test, thus serving as a reference for testing and measurement of complex optics. Due to...
Design of Ultra-lightweight SIC Scanning Mirror Assembly
In order to realize the lightweight of the (165mm×96mm) rectangular scanning mirror assembly and ensure the surface accuracy of the mirror and the support stiffness of the assembly, a back support method developed by MG-Optics with the integration of cone-sleeve and flexible joints was proposed, and the weight of the mirror assembly designed with this method is less than 0.5kg. Back structure of the ultra-lightweight scanning Mirror The mirror body was made of silicon carbide and the...
Metal aspheric mirror processing technology
The strength of metal aspheric mirror： Metal mirrors can be fully lightweight designed, and optical-mechanical integration installation and adjustment can be designed to simplify the structure of the back support of the mirror. Metal materials are generally obtained by casting. Metal materials have good thermal conductivity, relatively large coefficient of expansion, and are easily affected by temperature. However, metal materials have the advantages of good processing technology and short...
