The use of wavelength range can be divided into 3 major series, visible series (known as glass cell, UV visible series) (known as quartz cell series), infrared light (known as infrared cell). 翻译结果5复制译文编辑译文朗读译文返回顶部 ...
To provide a light absorbent that can block visible light in the short wavelength range including both the wavelength range of 380 nm-400 nm, which is difficult to block with conventional ultraviolet absorbers, and the wavelength range of 400 nm-420 nm, which badly affects eyes, and a ...
This variable quantity could be called the “wavelength.” As it varies in the visible spectrum, the light apparently changes color from red to violet. If we explore the spectrum systematically, from long wavelengths toward shorter ones, we would begin with what are usually called radiowaves. ...
