Introduction to the protection principle and processing of laser protective glass

Taixing Hechen Crystal specializes in the production of laser protective glasses. We know that ionizing radiation can usually cause changes in the chemical balance of cells, and certain changes can cause cancer. For example, it causes damage to the genetic material DNA in the cells in the body. This effect may even be passed on to the next generation, leading to malformations and congenital leukemia in the new generation. Under the exposure of a large amount of ionizing radiation, the human body may cause disease or death within a few hours or days. Unlike ionizing radiation, non-ionizing radiation is far less harmful to human safety than ionizing radiation.

However, if people who work with laser optical glass do not strictly follow the laser use place or laser operating regulations, they will also cause damage to the safety of the human body. Intense laser radiation usually interferes with the body’s biological clock, leading to disturbances in the body’s ecological balance and neurological dysfunction, causing headaches, fatigue, drowsiness, agitation, memory decline, inattention, skin fever, hair loss, heart palpitations, arrhythmia and blood pressure disorders And other symptoms. The effects of laser radiation on the brain and nervous system are manifested as decreased secretion of pineal gland, rhythm disturbances, and a series of clinical symptoms. Laser radiation can also damage cell membranes, affect children's development, cause women's menstrual disorders and male sexual dysfunction, and even lead to a sudden decrease in the number of sperm in men's semen or no sperm. Direct laser radiation can cause permanent damage to people’s eyesight and even blindness. Direct laser radiation can also burn human skin. In particular, lasers in the ultraviolet to blue light band cause the most serious damage to the skin.

Taixing Hechen Crystal Optical Glass Material: K9 Quartz Imported Quartz Sapphire and other optical materials Surface finish: 20/10 Diameter tolerance: +0.0/-0.10mm Center thickness tolerance: ±0.10mm Center tolerance: 3-5 arc minutes focal length tolerance ：±1% Aperture: 1-5 Partial Aperture: 0.2-0.5 Clear Aperture: 90% Coating: Broadband Anti-Reflection Coating

(1) The laser should be operated under good lighting conditions, so that the size of the pupils can be reduced and the damage to the eyes can be reduced;

(2) Do not wear jewelry, because the laser may reflect through the jewelry and cause damage to the eyes or skin;

(3) When operating the laser, be sure to place the object with specular reflection in a suitable position or move it away altogether;

(4) Cannot look directly at the laser beam deliberately;

(5) If you suspect that the laser is potentially dangerous, you must stop working and immediately let the laser safety worker conduct an inspection;

(6) Each type of laser and laser equipment should provide the greatest safety protection measures for the operator. Generally, only Class 1, Class 2, and Class 3a lasers are allowed to be used for experimental demonstration.

When the retina is irradiated by a high-intensity laser, it can cause pain to the optic nerve and damage the retina. The human eye is a biofocusing system, and the power density acting on the retina after focusing can be increased by 2 to 5×105 times than before entering the cornea. Obviously, the possible damage to the human eye caused by highly parallel lasers must be paid attention to. The damage of laser to eyes is related to laser wavelength, power or energy, pulse width, environment and so on. The greater the power, the shorter the wavelength, the more serious the damage; at night or in a dark room, the pupils are larger, and the energy entering the eyes is greater, which is more harmful. The damage of laser to the skin is mainly burns. Studies have shown that dark skin has a higher absorption rate than lighter skin; the skin has a higher absorption rate of CO2 laser: the absorbed energy is mainly deposited in the superficial layer of the skin.

The above is an introduction to the protection principle and processing of laser protective glass. Taixing Hechen crystal laser lens wiping steps:

1 Wash hands clean, blow dry or wait to dry

2. Put on finger cots

3.Gently remove the lens to check

4.First use an air ball or nitrogen to blow off the dust on the surface of the lens

5.Use a cotton ball moistened with lens fluid to stick away the residue

6. Gently wipe with lens wiper with an appropriate amount of lens wiper liquid. Do not wipe by rotating

7. Replace the lens cleaning paper, and repeat step (6), do not reuse the same lens cleaning paper

8. Blow the mirror surface clean with an air ball
