G03B APPARATUS OR ARRANGEMENTS FOR TAKING PHOTOGRAPHS OR FOR PROJECTING OR VIEWING THEM; APPARATUS OR ARRANGEMENTS EMPLOYING ANALOGOUS TECHNIQUES USING WAVES OTHER THAN OPTICAL WAVES; ACCESSORIES THEREFOR (optical parts of such apparatus G02B; photosensitive materials or processes for photographic purposes G03C; apparatus for processing exposed photographic materials G03D)
Introduced: September 1968
Description
G03B encompasses apparatus for image capture using optical and analogous non-optical wave techniques, along with devices for image projection and viewing. This subclass covers camera designs, photographic recording mechanisms, optical systems for image formation, and complementary accessory components. It extends to analogous imaging technologies employing non-optical waves (such as X-rays, electron beams, or other radiation), provided they serve analogous functions to optical photography. Related specialized areas like cinematography, electrography, and holography are classified separately within G03.
