Description

Technical Field

[0001] The utility model relates to the technical field of wave plate light alignment devices, in particular to a glued true zero-order wave plate light alignment device. Background Art

[0002] The glued true zero-order wave plate is an optical element made by gluing two pieces of materials with different optical properties together. This wave plate can rotate the polarization state of the incident light by 90 degrees without introducing any phase change, that is, it realizes the function of a true zero-order wave plate. In order to ensure the total phase delay accuracy of the wave plate and the accuracy of instrument measurement, it is often required that the optical axes of each chip constituting the composite wave plate be strictly aligned and calibrated according to the designed angle, and an alignment device is required;

[0003] The existing glued true zero-order wave plate light-aligning device is usually composed of a light source, a polarizer, a light-aligning tooling, an analyzer, a detector and a computer. The light source emits linearly polarized light. After passing through the glued true zero-order wave plate, the polarization state of the light will rotate, but the amplitude of the light remains unchanged. The detector detects the light signal passing through the analyzer, which can verify the effect of the glued true zero-order wave plate on light. The common detector, i.e., the light intensity sensor, is usually fixed to the inside of the light-aligning device housing with bolts. There are many components inside the light-aligning device, and it is inconvenient to remove the light intensity sensor from the inside of the housing, which causes many inconveniences when the light intensity sensor needs to be repaired and maintained. Common light-aligning devices are usually supported by a bracket of fixed height, and the heights of operators are different. It is not convenient to adjust according to the height of the inspector. The setting of the light-aligning device that is too high or too low can easily cause many inconveniences for the operator to operate. For this reason, we propose a glued true zero-order wave plate light-aligning device. Utility Model Content
