You probably already have some understanding of ultraviolet light. UV rays are what we’re protecting ourselves against when we wear sunscreen and avoid sunburns. But how does UV differ from other types of light? The difference is in the wavelength.

Thus, in G03B aspects of apparatus or methods for taking photographs using an electronic image sensor [EIS] for image capture are classified insofar as they correspond to those of said apparatus or methods for taking photographs using light sensitive film, i.e. insofar not peculiar to the presence or use of the EIS, e.g. mounting of optical elements or flashes, and their related controls insofar they are not peculiar to the presence of the EIS, e.g. exposure, focus, (opto-) mechanical motion blur (anti-shake);

In G03B, aspects of apparatus or methods for projecting or viewing images using an electronic spatial light modulator [ESLM] are classified insofar as they correspond to those of said apparatus or methods for projecting or viewing images using film stock, photographic film or slides, i.e. insofar as not peculiar to the presence of the ESLM, e.g. mounting of optical elements not peculiar to the presence of the ESLM, and their related controls not peculiar to the presence of the ESLM, e.g. cooling, beam shaping, optical keystone correction.

UV light in different forms is frequently used for disinfection in healthcare facilities, for food manufacturing, and in agricultural settings. Its shorter wavelength makes Far-UV the effective choice for disinfection. A Far-UV light can cause the physical destruction of viruses, bacteria, and fungi so that they will no longer cause infection or harm. Further, Far-UV light can cause this destruction quickly, without the use of potentially harmful solvents, making it an attractive choice for infection control tools.

Within the category of ultraviolet, there are subtypes also divided by the difference in wavelengths. Most commonly, you will see UV light divided into A, B, and C subtypes with A having the longest wavelength (320nm to 400nm) and C having the shortest (100nm to 290nm). UV-A light is also referred to as “blacklight,” UV-B light (290nm to 320nm) is what causes sunburns in humans upon exposure and UV-C light mostly absorbed by the atmosphere so we have little contact with this type of light.

When it comes to scientific use, different categories are used to distinguish one type of UV light from another. For these purposes, UV subtypes are Near, Middle, and Far, with Near-UV matching up closest to UV-A, Middle-UV matching with UV-B and Far-UV matching with UV-C in terms of wavelength.
