Embodiment Construction

[0015] see figure 1 and figure 2 As shown, the present invention provides a laser processing cover, which includes:

[0016] A metal cover 1, which is hollow hemispherical, has a round hole 11 for fixing the laser head 3 in the middle part of the metal cover 1, and has a plurality of visible windows 12 on the side wall;

[0017] A plurality of goggle lenses 2 are fixed on the visible window 12 on the metal cover 1 .

[0018] The structure of the goggle lens 2 is: a substrate 21, the material of the substrate 21 is transparent toughened phosphate glass, and the thickness is 1.0-1.2mm. The substrate 21 is vacuum-coated with the first coating 22 on the side facing the laser A by high-frequency sputtering. The material of the first coating 22 is an alternating sputtering structure of zirconia and silicon dioxide, and the number of layers of the two is alternately evaporated. 3-6, the thickness of each layer is 400-500nm. The first cover sheet 25 is covered on the coating film...

Abstract

The invention discloses a laser machining cover which comprises a metal cover and a plurality of eye protective lenses. The metal cover is in the shape of a hollow hemisphere, a circular hole used for fixing a laser head is formed in the middle of the metal cover, and a plurality of visible windows are arranged on the side walls of the metal cover; the eye protective lenses are fixed onto the visible windows in the metal cover. The laser machining cover has the advantages that visual fields are bright owing to the laser machining cover, the transmittance of the lenses on the visible windows for laser beams with the wavelengths of 1064nm can reach 10-7 magnitude and is lower than a safety protection threshold value for human eyes, and accordingly the human eyes can be effectively protected; the laser machining cover is simple in manufacturing process, and the production cost can be greatly reduced.

Description

technical field [0001] The invention relates to a laser processing accessory equipment, and further relates to a laser processing cover for a specific wavelength of 1064nm. Background technique [0002] Nd:YAG solid-state laser is a kind of laser widely used. Its laser wavelength is 1064nm. Laser has been widely used in military affairs, industrial processing and medical cosmetology. damage to the site. Short-term intense irradiation of the eyes by lasers with different wavelengths will cause corneal or retinal burns, and if the eye is often exposed to more than a certain limit, it may also cause keratitis, lens opacity and retinal damage. [0003] Laser damage to the eye is mainly in the part of the eye tissue that absorbs the most energy per unit volume. When the laser emits wavelengths in the visible and near-infrared spectral range (0.4 μm-1.4 μm), it may cause retinal damage. The light of this part of the wavelength that the laser enters the eye directly or after bei...
