visible radiation

基本解释

The visible radiation characteristics of midcourse targets are very important for detecting, tracking and attacking a target.
中段目标的可见光辐射特性对目标的探测、跟踪与打击具有重要的指导意义。
An incandescent lamp, two interference filters and two Si P-I-N detectors are used as visible radiation source, dispersive elements and photo-electric cells, respectively.
白炽灯、二块干涉滤色片和二只硅光电二极管分别作为可见辐射光源、色散元件和光电转换器。
Compared with the results in the literature, it was found that the visible radiation intensity is usually weak, while ultraviolet and infrared radiation intensities depend on the discharge conditions.
与文献中的结果进行比较，发现各种条件下的电晕放电的可见光区辐射强度一般都比较弱，而紫外区与红外区辐射的强弱则与具体的放电条件有关。

When it is ground into nanoparticles it can still block harmful ultraviolet radiation, but it allows visible light to pass straight though, which means modern sunscreens can appear completely transparent, while offering the same protection as the old white stuff.
ECONOMIST: The risk in nanotechnology
The telescope gathers and focuses electromagnetic radiation (usually, but not always, visible light) to make far-off objects seem brighter and closer.
FORBES
Even something too small to emit visible light will probably give off radio waves and infra-red radiation (Jupiter does).
ECONOMIST: X marks the spot

electromagnetic radiation that causes the sensation of sight light. It has wavelengths between about 380 and 780 nanometres
