MG-Optics developed the infrared astronomical telescope used in Antarctica according to the customer's tough requirements. The primary and secondary mirrors are developed with Zerodur and the structural parts are developed with low expansion indium rigid material to ensure that the primary and secondary mirror positions do not change significantly under the severe temperature environment. Through the finite element analysis of the whole system, the offset of the primary and secondary mirrors ≤0.023mm under the temperature of -40℃ to- 80℃, which can achieve excellent image quality without focusing. From optical path design, the mirror assembly and main supporting structure design and manufacturing to the test of Optical System, MG-Optics provide you one-step custom optics solution to make the final product has unsurpassed reliability, world-class quality and an unbeatable price-to-performance ratio. MG-Optics will provide you one-stop custom optical system design and alignment services. Just give us your specific requirement, we will study and give the professional design report, including optical system design, primary and secondary mirror assembly design and main supporting structure design and assessment. The fabrication and test of the optical system will also offered based on your specifications.
