Description

Technical Field

[0001] The utility model relates to the technical field of light shields, in particular to a light shield for a picosecond laser spot removal instrument. Background Art

[0002] Lens hood is a device installed on the front of photographic lenses, digital cameras and camcorders to block harmful light. It is also one of the most commonly used photography accessories. Lens hoods are made of a variety of materials such as metal, hard plastic, and soft rubber. Most 135 lenses come with lens hoods as standard, while some lenses need to be purchased separately. The models of lens hoods used by different lenses are different and cannot be interchanged. Strictly speaking, the lens hood is a component of the lens optical system. A lens is composed of several or dozens of lenses. Each lens has two reflective surfaces, and a lens has dozens of reflective surfaces! The more reflective surfaces, the greater the impact on the lens imaging! Especially when shooting against the light or side backlight, multiple reflective surfaces will interfere with each other to form a halo. The halo will make the picture color dim (color unsaturated) or have flare. Sometimes the picture taken looks like a layer of mist. In fact, this is caused by not using a lens hood, not the quality of the lens! The inner wall of a high-quality lens hood has been subjected to multiple extinction treatments. The reflectivity of its inner wall is only about 10%, and it will not refract the lens when used. Using a lens hood can play a good role and effect in suppressing the halo of the picture, preventing stray light from entering the lens, blocking rain and snow splashing, protecting the camera and lens from accidental collisions, and giving full play to the potential quality of the lens optics.

[0003] After searching, a Chinese utility model patent disclosed with publication number CN203777514U discloses a light shield for shielding ineffective therapeutic light to prevent light pollution. The light shield includes a first light shielding portion and a second light shielding portion, the interior of the first light shielding portion and the second light shielding portion are both made of black cloth, the first light shielding portion and the second light shielding portion are sewn together by sutures, the second light shielding portion is a conical or annular surface, and the first light shielding portion is a cylindrical or conical surface. The therapeutic light emitted by the lamp head of the photon therapy equipment and the emitted light shining on the patient's treatment surface can be effectively blocked by the light shield to prevent large-angle stray light and reflected light on the patient's treatment surface from entering the human eye, thereby achieving effective shielding of ineffective therapeutic light and preventing light pollution. The light shield provided by the utility model solves the problem of light pollution caused by ineffective therapeutic light.

[0004] However, the current light shield used to block ineffective therapeutic light and prevent light pollution is not convenient to load and unload. When it is needed, it is often difficult to load and unload it quickly, making it difficult to use. Not only that, the light shield has a weak adjustment function. When the bottom of the light shield needs to be adjusted during use, it cannot be adjusted to the height as needed, causing adverse effects. Utility Model Content

The setting of the anti-skid rubber protrusions 7 increases the friction force at the connection between the bottom of the fixing fixture 1 and the sub-buckle 4, so that the shading arc cover 2 is fixed to the bottom side wall of the fixing fixture 1, and the sub-buckle 4 is effectively prevented from falling off the side wall of the fixing fixture 1. The fixing fixture 1 is fixedly connected with an anti-skid rubber pad 5. The setting of the anti-skid rubber pad 5 further improves the fixing effect of the fixing fixture 1 on the probe of the picosecond laser spot remover, and at the same time, the side wall of the probe of the picosecond laser spot remover is buffered and protected. The flexible cloth cover 8 is supported by the rubber support ring to prevent the flexible cloth cover 8 from being deformed during use, thereby affecting the shading effect. By adjusting the setting of the reference line 9, the staff is assisted to make quick adjustments, so that the bottom height of the device can be quickly adjusted while ensuring the accuracy of the adjustment.
