Product features

B& P laser safety glasses are a kind of high efficiency explosion-proof safety goggles made from polycarbonate (PC) and light absorption material of specific wavelength imported from Australia. Its optical safety performance fully meets gJB1762-93 “Physiological health standard of Laser Protective Lens”. Wear comfortable, beautiful, safe and reliable. Laser safety glasses adopt the principle of light absorption: they have no selectivity to the light source and can protect all kinds of diffuse light safely. There is no selectivity to the incident Angle of the light source, and it can fully protect the laser and strong light of specific band. Light reacts faster. The decay rate is higher. The surface is not afraid of wear and tear, even if there is a scratch, it does not affect the safety of light protection.

Introduction to Laser glasses

The principle is introduced

B& P/T-REX laser safety goggles are based on the principle of light absorption: no selectivity to light source, so they can safely protect all kinds of diffuse light. There is no selectivity to the incident Angle of the light source, and it can fully protect the laser and strong light of specific band. Light reacts faster. The decay rate is higher. The surface is not afraid of wear and tear, even if there is a scratch, it does not affect the light safety protection, can effectively protect your eyes in all directions.

1. Reflective laser protective lens is coated with multiple reflective medium layers on the optical glass surface of the base.

Advantages:

1. Simple process;

2. High visible light transmittance;

3. High attenuation rate;

4. Fast light reaction time & LT; 10 to 9 seconds;

Disadvantages:

1. Severe selectivity of light sources. The incident light source must be facing the protective mirror (the incident light is the normal direction of the mirror), and its protective effect is the greatest, and vice versa.

Otherwise there will be blue drift, the greater the incident Angle, the shorter the protective wavelength drift. When the protective band is not wide enough or the protective wavelength is short enough, the complete failure in oblique incidence may occur.

2, reflective media layer easy to take off, and fall off not easy to observe the naked eye, which is also the most dangerous,. The reflector layer in China usually falls off in about a year. The higher the optical attenuation rate, the thicker the plating medium layer, the easier to fall off.

Ii. Special absorbent is added to the base material PC by absorption protective lens.

Advantages:

1. There is no selectivity to the light source, which can safely protect all kinds of diffuse light; Incident light at any Angle is equally well protected.

2. High attenuation rate;

3, the surface is not afraid of wear, even if there is a scratch, does not affect the light safety protection;

4. Fast light reaction & LT; 10 to 9 seconds;

5. At the same time, it has a good shielding property for dazzling white light generated during laser operation.

Disadvantages: low visible light transmittance

Three; Optical density (OD)

The percentage of laser light at a particular wavelength that can pass through a laser protective lens.

For example; OD1+ : means that 10% of the laser at a certain wavelength can pass through the laser protective glasses

The same goes for:

OD2 + : 1%

OD3 + : 0.1%

OD4 + : 0.001%

OD5 + : 0.0001%

OD6 + : 0.00001%

OD7 + : 0.000001%

4. Visible light transmittance (VLT%)

The percentage of visible light that can pass through laser protective glasses. The higher the VLT%, the brighter the lens and the clearer the field of vision.

At the same time, optical density (OD) will affect the light transmittance. Since our laser protective glasses are absorption type, some light transmittance will be lost if we want to achieve high optical density according to the production process. If the optical density requirements are lower, you can improve the transmittance, so that the field of vision will be clearer. Laser protective eyewear is a kind of high efficiency explosion-proof safety eyewear made of PC polymer material and light absorption material of specific wavelength.

Laser protective glasses has a variety of types, different materials, different principle, different applications, laser protective glasses are worn in the laser operating environment, put in a non-working environment will be a little does not adapt, a long time to adapt, laser protective glasses is laser effective protective, must according to the specific use requires a reasonable choice of laser protective goggles. When selecting the protective lens, the maximum irradiance or the maximum irradiance of the laser output is firstly determined according to the parameters such as the maximum output power (or energy) beam diameter and pulse time of the laser used. Then, the minimum optical density value of glasses is determined according to the maximum allowable radiation amount of phase wavelength and exposure time (the limit value of eye exposure), and the appropriate protective lens is selected accordingly.
