Problems solved by technology

[0004] In order to overcome the inconsistency between the optical axis of the ellipsoidal condenser and the optical axis of other components in the optical system in the existing collimating solar simulator optical system, the resulting low utilization rate of light energy in the system and the convergence to the ellipsoidal condenser The light at the second focal point no longer satisfies the Gaussian distribution, which affects the uniformity efficiency of the optical integrator, resulting in poor radiation uniformity of the solar simulator

Abstract

The invention discloses an installing and adjusting method for a collimation type solar simulator optical system. A reference optical axis is established through a theodolite I and a theodolite II, and a pentaprism, a guide rail, a tool reflector and a laser device are matched to conduct installing and adjusting capable of guaranteeing optical axis consistency on a collimator objective, an opticalintegrator, a steering plane reflector, a spherical reflector and an ellipsoid collecting lens, and the light energy utilization rate and irradiation uniformity of a collimation type solar simulatorcan be effectively improved.

Description

technical field [0001] The invention relates to a method for installing and adjusting an optical system, in particular to a method for installing and adjusting an optical system of a collimating solar simulator. Background technique [0002] According to different optical systems, solar simulators can be divided into coaxial diverging system and coaxial collimating system. The former has a relatively simple structure, lower cost than the latter, and high utilization rate of light energy. However, since there is no collimating objective lens, the output The light beam is not collimated, and is suitable for occasions without collimation requirements; the latter is relatively expensive, using a collimating objective lens, and placing a field diaphragm at the focal plane of the collimating objective lens, by changing the field light The size of the diaphragm can simulate different collimation angles of the sun, which has high uniformity and is widely used, but the light energy u...
