Description

Technical Field

[0001] This utility model relates to the field of optical component testing technology, and in particular to an optical component environmental exposure test chamber. Background Technology

[0002] Optical elements are the basic building blocks of optical systems, primarily used for imaging and other optical functions. Common optical elements include lenses, prisms, and mirrors, which play an imaging role in optical systems. In addition, there are some optical elements with special functions, such as reticles, filters, and gratings, used for beam splitting, image transmission, and filtering. Optical elements are usually made of transparent materials, such as glass or crystal. Plastic lenses or glass lenses can be selected according to needs. New types of optical elements, such as holographic lenses, gradient refractive index lenses, and binary optical elements, have also been developed in recent years. Optical elements have wide applications in many fields, including astronomy, military, transportation, medicine, and art. In optical communication, optical elements such as optical fibers and lenses play a role in signal transmission and amplification.

[0003] A search revealed an existing technology (publication number: CN211292502U) for an optical lens weathering resistance testing system. The document states that it "includes a base, with a motor fixedly connected to the left side of the bottom of the base's inner cavity. A driving bevel gear is fixedly connected to the output end of the motor. A rotating rod is movably connected to the bottom of the base's inner cavity, and a driven bevel gear, which cooperates with the driving bevel gear, is fixedly sleeved on the surface of the rotating rod. A central processing unit and a solid-state memory are fixedly connected to the right side of the bottom of the base's inner cavity, respectively. A heat-insulating shell is fixedly connected to the top of the base, and a [missing information - likely a device or component] is fixedly connected to the inner cavity of the heat-insulating shell." The vacuum chamber, wherein the top of the rotating rod extends sequentially through the base, the heat-insulating shell, and the vacuum chamber to the inner cavity of the vacuum chamber and is fixedly connected to a metal mesh plate, is described in this utility model. This invention solves the problem of poor testing results in existing optical lens weathering resistance testing systems by using a base, motor, driving bevel gear, driven bevel gear, central processing unit, blower, heater, first solenoid valve, humidifier, placement slot, heat-insulating shell, temperature sensor, humidity sensor, second solenoid valve, dehumidifier, metal mesh plate, rotating rod, vacuum chamber, chamber door, door panel, touch screen, solid-state storage, and cooling fan in combination.

[0004] However, existing technology cannot fix optical lenses of different sizes, which reduces the effectiveness of the equipment. At the same time, the heating effect of the equipment is limited during the heating process and cannot guarantee that the heating effect of multiple lenses is equal. Therefore, it is necessary to design an environmental exposure test chamber for optical components. Utility Model Content

The controller controls the electrical devices on the chamber, and the electrical box is used for power supply. The protective cover protects the motor from the outside, the sound-absorbing panel reduces noise, and the ventilation vents dissipate heat from the motor. Attached Figure Description
