我们所以型号都可以做成真彩滤镜。2、关于蓝光：a. 滤镜常态（不变黑）

So we can make models true color filter. <br>2, blue light on:. A filter when the normal (constant black), average transmittance blue filter 7% (at this time because there is no blue light (welding) is generated, only the blue light contained in ambient light, which when welder wearing than not wearing welding cap weld cap by less harmful blue light. <br>B. when darkening filter (in this case very strong welding light blue), the filter blue light transmittance is less than this time color number 1/3 of the visible light transmittance, such as <br>the color number is 9, corresponding to the visible light transmittance was 0.037%, blue light transmission of less than 0.012%. <br>color is 10, corresponding to the visible light transmittance is 0.015%, the blue light transmittance of less than 0.005%. <br>............ .. <br>............ .. <br>3, we will prepare two sets of SUN29B delivery air system to you.

We can make real color filters so models.<br>2. About Blu-ray: a. When the filter is normal (unchanged black), the average pass rate of the filter's blue light is 7% (because there is no blu-ray light source (welding) and only the blue light contained in ambient light, when the welder wears a solder cap less harmful to blue light than not wearing a solder cap.<br>b. When the filter is blackened (when the blue light in the weld light is very strong), the transmission rate of the filter's blue light is less than 1/3 of the visible light transmission rate of the color number at this time, for example<br>The color sign is 9 o'clock, the corresponding visible light transmission rate is 0.037%, blue light transmission rate is less than 0.012%.<br>The color sign is 10 o'clock, the corresponding visible light transmission rate is 0.015%, blue light transmission rate is less than 0.005%.<br>..............<br>..............<br>3, we will prepare 2 sets of SUN29B distribution wind system to you.

All our models can be made into true color filters.<br>2. About blue light: A. when the filter is in normal (constant black), the average transmission rate of blue light of the filter is 7% (because there is no blue light source (electric welding) at this time, only the blue light contained in the ambient light, at this time, the welder wearing the welding cap is less harmful than not wearing the welding cap.<br>b. When the filter turns black (at this time, the blue light in the welding light is very strong), the blue light transmittance of the filter is less than 1 / 3 of the visible light transmittance of the color number, such as<br>When the color number is 9, the transmittance of visible light is 0.037%, and that of blue light is less than 0.012%.<br>When the color number is 10, the transmittance of the corresponding visible light is 0.015%, and that of the blue light is less than 0.005%.<br>... ..<br>... ..<br>3. We will prepare 2 sets of sun29b distribution wind system for you.<br>
