Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of testing devices, in particular to a testing device for testing light spots and angles. Background Art
[0002] The mainstream package form of the 100G optical fiber transceiver module in the data center is QSFP28, which integrates 4 semiconductor lasers, a photodetector array and its driving circuit, and a passive CWDM4 component. In order to integrate the CWDM4 component into the QSFP28 module, it needs to be designed as small as possible, and the size requirement is more stringent than the CCWDM module (a compact CWDM module) in telecommunications applications. This leads to the birth of a new product: the Z-block component. The back part of the rhombus prism of the wavelength division multiplexing transmission optical path of the Z-block component is coated with a high-reflection film. The optical signals emitted from the four collimators on the right pass through the corresponding filters, reach the collimator at the common end on the left after different reflection times, and are coupled to the output optical fiber. Since the optical path in the rhombus prism is long, reaching the order of 10mm, a total of five collimators must be used. The coupling of the reflected optical path and the collimated beam is very sensitive to the angle, so an integrated collimator array cannot be used, and each input collimator must be adjusted and aligned independently, and the assembly process is relatively complicated.
[0003] The Z-block component needs to test the spot and angle, so an automatic test system has been developed for the Z-block product, which can automatically measure the angle and spot at the same time, solving the bottleneck of test efficiency and testing accurately. The existing test cannot be completed on the same machine, and the spot test of 4 channels needs to be completed manually, which cannot meet the requirements of high-end customers in terms of test efficiency and accuracy.

[0028] The utility model proposes a testing device for testing light spots and angles, which includes a testing table 1, a testing device 2, a material fixture 23, a combined testing component 21, a collimating component 22, a slit beam analyzer 214, a spectral confocal displacement sensor 216, and a Y-axis displacement component.

[0029] Among them, the principle of the slit beam analyzer 214 is to scan the entire beam cross section in sequence through the slit pair of the rotating disk, one group of slits scans along the X axis of the beam, and the other group of slits scans along the Y axis. The X and Y axes are defined by the user and generally correspond to the major axis and minor axis of the ellipse. The light beam passes through the slit and is incident on the photodetector. The light intensity measurement result corresponds to the slit position. These data are collected during the slit scanning process, and the sum of all the light entering the slit is measured and recorded by the photodetector; the principle of the spectral confocal displacement sensor 216 is to pass a beam of white light (or multi-wavelength mixed light) through a small hole, and focus different wavelengths on the optical axis through the lens, and form a rainbow-shaped distribution band in a dispersed manner. Only the light irradiated at the intersection of the optical axis and the surface of the object passes through the spectroscopic component and irradiates the spectrum analyzer through the small hole. The distance from the lens to the object to be measured can be obtained by decoding the wavelength.
