G02B 30/34 Stereoscopes providing a stereoscopic pair of separated images corresponding to parallactically displaced views of the same object, e.g. three-dimensional [3D] slide viewers
Introduced: January 2020
Full Title
Full titles differ between systems:
Optical systems or apparatus for producing three-dimensional [3D] effects, e.g. stereoscopic images > by providing first and second parallax images to an observer’s left and right eyes > Stereoscopes providing a stereoscopic pair of separated images corresponding to parallactically displaced views of the same object, e.g. three-dimensional [3D] slide viewers
Optical systems or apparatus for producing three-dimensional [3D] effects, e.g. stereoscopic images (in microscopes G02B21/22) > by providing first and second parallax images to an observer's left and right eyes > Stereoscopes providing a stereoscopic pair of separated images corresponding to parallactically displaced views of the same object, e.g. three-dimensional [3D] slide viewers
IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
IPC defines codes here since 2020.
