Laser safety glasses
New protective glasses in the laser operation and other useful use of the process of human naked eye can not see the wavelength of 900nm Laser safety glasses, wearing this protective mirror can be seen in the case. Tests have shown that the CMOS chip of the goggles is also sensitive to lasers up to 1064 nm wavelength, thus providing convenience for Laser safety glasses workers to operate non-visible infrared lasers. They do not need to use a special infrared card to find the Laser safety glasses point, as shown in Figure 6, for the 1064nm wavelength of the infrared picosecond laser oscillator, the Laser safety glasses in the cavity of the lens on the spot position at a glance. When we introduce the structure of the protective glasses, it shows that its control handle has the control image red, blue, green three color channel strength, and adjust the image brightness and other functions, which in the laser adjustment process is still quite useful.
Titanium sapphire Laser safety glasses oscillator is filled with green light, because too dazzling and can not directly observe the cavity with the naked eye, even through the formation of electronic images of protective glasses, although not dazzling, but perhaps because the green is too deep eyes still feel uncomfortable, this time We can control the intensity of the green color channel in the image by controlling the operating handle of the protective glasses. When the intensity reduced to the original 50%, the image of the green part of the basic is not so glaring, when the intensity reduced to the original 20%, the image of the green component is basically gone, we can then through the handle to the image The brightness of the appropriate increase, you can get the image, so that the light can be gently adjust the control Laser safety glasses . What kind of image is appropriate, which is different, the user can adjust the image parameters according to their own requirements.
People in the adjustment of lasers, especially the oscillator, the laser before the start, often with fluorescence to align the laser light path and adjust the various frames, but the fluorescence is generally weak, and if the near infrared light, naked eye can not see, People often use infrared night vision to observe the fluorescence position. But because of its larger head, it is not very convenient to use, if we use our new laser protection glasses, whether to see this fluorescence? The answer is yes. Spot is the laser of the Ti: sapphire laser oscillator in the mirror on the image, you can see, the relative light background is still relatively obvious, if the closure or weaken the intensity of indoor light, the effect will be more significant.
Because of our new type of protective glasses with CMOS photoelectric image detection and DSP high-speed digital image processing functions, it has the above described several features, so as to laser adjustment and laser applications has brought great convenience.
