The present invention relates to a change in the spectral wavelength range of devices, such as narrowing the range to make spectral wavelength devices. 所述器件包括用于光子能量上转换的介质,其含有至少两种组分和其中分布有所述至少两种组分的基质,其中第一组分能吸收第一波长区域w≤λ1≤x的光,第一组分...
According to the International Commission on Illumination (CIE) definition, light is “radiation within the spectral range of visible radiation, i.e., the optical radiation capable of causing a direct response of the visual system to stimulation” [6]. ...

Light- proof tube and aperture diaphragm are cooled and diameter D of optical surface of main mirror corresponds to condition D>fd/(f-L)+2Lsinω, where f is focal distance of main mirror; d is diameter of aperture diaphragm; L is distance from main mirror to aperture diaphragm; &...
Freshwater-dwelling algae like these are among those able to sense a surprisingly wide spectrum of light. Credit: J. Clark Lagarias, UC Davis (Phys.org) —Aquatic algae can sense an unexpectedly wide range of color, allowing them to sense and adapt to changing light conditions in lakes and ...
By far, the most impressive feature of the scope is the proprietary Twilight Max Light Management System, a combination of premium lens clarity and full-spectrum lens coatings. This means I get an extra 20 minutes of shooting light. This can make all the difference when I’m trying to hit...
Through this unique programme, students have access to awhole rangeof master's programmes. 通过这样独一无二的本科项目, 学生在毕业后几乎可以就读任何专业的硕士项目. 互联网 What we call visible light is a tiny portion of thiswhole range, or spectrum. ...
Dynamic Range (DR) is the range of exposure, i.e., scene brightness, over which a camera responds with good contrast and good Signal-to-Noise Ratio (SNR). This is a scene-dependent image quality factor that incorporates sensor sensitivity, noise, and stray light. High Dynamic Range (HDR)...
2.2.2Free spectrum range According to Fresnel's law, when a beam of light is incident into a denser medium from a thinner medium, and the incident angle is greater than the critical angle, most of the light will be totally reflected. Suppose alaser beamis coupled to an optical resonant ...
The spectrum of light has received little attention as an ecological factor and in this review we highlight the importance of a changing light environment in plant range shifts under conditions of global warming. Although distinct clinal responses to light quality have not been earlier reported, som...
