Embodiment Construction

[0012] A preferred specific embodiment is provided below in conjunction with the accompanying drawings to further describe the present invention in detail.

[0013] like figure 1 As shown, the dome transmittance detection device of this embodiment includes: a light source interferometer 1, a first concave reflector 2, a dome 3, a second concave reflector 4, a detector 5, a control software system 6, and a spherical center Type measurement platform 7, biaxial measurement turntable 8, fairing tooling 9, protection device 10 and support structure 11, test light convergence point (sphere center) 12.

[0014] The detector and the light source interferometer are arranged horizontally up and down, and a two-axis measurement turntable is horizontally set between the detector and the light source interferometer. The two-axis measurement turntable can rotate around an axis perpendicular to the horizontal plane in the horizontal plane, and can also perform pitching motions. The spherica...

Abstract

The invention relates to a detection device for testing the transmittance of the film layer of an optical dome. The test light is converted into converging light in the vertical direction through the concave reflector. The converging light converges at the spherical center of the fairing and passes through the tested fairing in a normal way, and converges to the detector through another concave reflector to detect the rectification. The transmittance of the cover film layer, and then rotate the biaxial measurement platform to detect the transmittance of the entire fairing film layer. The technical solution of the invention can solve the problem that the measurement space of the current spectrometer is limited, the transmittance of the entire film layer of the dome cannot be fully detected and the measurement is inaccurate.

Description

technical field [0001] The invention relates to a detection device for testing the transmittance of an optical dome film layer, and belongs to the technical field of optical detection. Background technique [0002] Since the shape of the dome of the optical element is a spherical surface, the size is large, and the transmittance of the wavelength range required by different dome is not the same. At present, the measurement space of the traditional spectrometer itself is limited, and it can barely measure small parts. It can only test the performance parameters of the partial film layer of the dome, and cannot fully detect whether the performance index of the entire film layer of the dome meets the coating requirements; It may completely coincide with the normal line on the spherical center of the tested spherical fairing, thus causing certain errors in the measurement results. Contents of the invention [0003] The invention provides a detection device for testing the tra...
