Description

Technical Field

[0001] This utility model relates to the field of auxiliary angle adjustment equipment technology, and in particular to a device for adjusting the optical angle of a collimator. Background Technology

[0002] Fiber optic collimators are widely used optical devices in the field of optics. However, when using fiber optic collimators for beam coupling experiments, it is necessary to adjust the optical angle of the collimator. Without this adjustment, the results obtained using the fiber optic collimator will contain significant errors. Traditionally, the optical angle adjustment of fiber optic collimators is achieved by using a beam analyzer to test the angle of the collimator and then working backward from the result to adjust the optical angle. This method is not only costly but also time-consuming in both testing and adjustment. Utility Model Content

[0003] In view of this, in order to solve the above-mentioned problems of high cost and long testing and adjustment time, the present invention provides a device for adjusting the optical angle of a collimator.

[0004] An embodiment of this utility model provides a device for adjusting the optical angle of a collimator, comprising: a light source, a circulator, and a highly reflective element, wherein...

[0005] The light-emitting end of the light source is connected to the first port of the circulator via an optical fiber. The second port of the circulator is connected to an optical fiber collimator via an optical fiber, and the optical fiber collimator is adapted to the high reflectivity element so that the light beam emitted from the optical fiber collimator is reflected by the high reflectivity element and then re-enters the optical fiber collimator. The third port of the circulator is connected to an optical power meter via an optical fiber.

[0006] Furthermore, it also includes an auxiliary platform, the working end of which is provided with a gripper, the gripper being clamped and connected to the fiber collimator.

[0007] Furthermore, the auxiliary platform is a six-axis robotic arm.

[0008] Furthermore, it also includes a support body, wherein the high reflectivity element is detachably and fixedly connected to the upper end of the support body.

[0009] Furthermore, the support structure is a lifting platform.

[0010] Furthermore, the high-reflectivity component is composed of several high-reflectivity mirrors.

[0011] Furthermore, the circulator is a three-port optical circulator.

[0012] Furthermore, the optical power meter is model number 6337D optical power meter.

[0013] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The device for adjusting the optical angle of a collimator according to this utility model can detect the power of light reflected from a highly reflective element by utilizing the characteristics of the three-port channel of the circulator to determine whether the fiber collimator is adjusted correctly. If there is a problem with the angle adjustment of the fiber collimator, then the light beam reflected into the second port of the circulator and exiting from the third port will be relatively small, and the measured power will definitely be low. Only when the fiber collimator is adjusted correctly can a large number of light beams be guaranteed to be emitted from the third port of the circulator, and the measured optical power will definitely be large. Therefore, the optical power measured by the optical power meter can be used to determine whether the fiber collimator is adjusted correctly. At the same time, the movable auxiliary platform and support body facilitate the adjustment of the entire testing device according to the needs. Attached Figure Description

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0017] Please refer to Figure 1 An embodiment of this utility model provides a device for adjusting the optical angle of a collimator, including a light source 1, a circulator 2, and a highly reflective element 5.

[0018] In this embodiment, the light source 1 is a laser light source, which is mainly used to generate light signals for testing. The light-emitting end of the light source is connected to the circulator 2 through an optical fiber, which ensures that the light beam enters the circulator 2.

[0019] Furthermore, in this embodiment, the circulator 2 is a three-port optical circulator, which contains three ports. According to the characteristics of a three-port circulator, when the light beam enters from the first port, it can only exit from the second port, and when the light beam enters from the second port, it can only exit from the third port. Therefore, the light-emitting end of the light source 1 is connected to the first port of the circulator 2 through an optical fiber, which ensures that the initial light beam is input from the first port of the circulator 2.

[0020] Meanwhile, the second port of the circulator 2 is connected to an optical fiber collimator 4 via an optical fiber, so that the light beam entering from the first port can exit from the second port and enter the optical fiber collimator 4. In this embodiment, the optical fiber collimator 4 is adapted to the high reflectivity element 5 so that the light beam emitted from the optical fiber collimator 4 can enter the high reflectivity element 5. Preferably, in this embodiment, the high reflectivity element 5 is composed of several high reflectivity mirrors to ensure that the light beam entering the high reflectivity element 5 can be effectively reflected. And by adjusting the position of the high reflectivity element 5, it is ensured that the reflected light beam can re-enter the optical fiber collimator 4 and enter the second port of the circulator 2 through the optical fiber.

[0021] The third port of the circulator 2 is connected to an optical power meter 3 via an optical fiber. The light beam reflected by the high reflector 5 enters the second port of the circulator 2 and exits from the third port. The optical power meter 3 can detect the power of the light beam exiting from the third port of the circulator 2. The power can then be used to determine whether the optical angle of the fiber collimator is adjusted correctly. It should be noted that the model of the optical power meter is 6337D optical power meter.

[0022] In this embodiment, an auxiliary platform 6 is also included. The working end of the auxiliary platform 6 is provided with a gripper 7, which is clamped and connected to the fiber optic collimator 4. Preferably, the auxiliary platform 6 is a six-axis robot, so that the attitude and position of the fiber optic collimator 4 can be adjusted by the auxiliary platform 6. Furthermore, a support body 8 is provided below the high reflective element 5. The high reflective element 5 is detachably fixed to the upper end of the support body 8. In this embodiment, the support body 8 is a lifting platform, so that the attitude and position of the high reflective element 5 can be adjusted as needed by the lifting platform.

[0023] The working principle of the device for adjusting the optical angle of the collimator in this embodiment is as follows: Utilizing the characteristics of the three-port channel of the circulator, the power of the light reflected from the highly reflective element can be detected to determine whether the fiber optic collimator is adjusted correctly. If there is a problem with the angle adjustment of the fiber optic collimator, the amount of light beam reflected into the second port of the circulator and exiting from the third port will be relatively small, resulting in a lower measured power. Only when the fiber optic collimator is adjusted correctly can a large amount of light beam be emitted from the third port of the circulator, ensuring a higher measured optical power. Therefore, the correctness of the fiber optic collimator adjustment can be determined by observing the optical power measured by the optical power meter. Simultaneously, the entire testing device can be adjusted as needed using the auxiliary platform and support.
