Bauhaus: The Bauhaus was first founded by Walter Gropius in
Weimar. In spite of its name, and the fact that its founder was an
architect, the Bauhaus during the first years of its existence did not
have an architecture department.
Telephoto Lens: specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length
Photomicrograph: micrograph prepared using an optical microscope, a process referred to as photomicroscopy

Vest Pocket Kodak: The Vest Pocket Kodak cameras were a best-selling folding camera series made by Eastman Kodak (Rochester), from 1912 to 1926. They were the first cameras to use the smaller 127 film reels.
Meniscus Lens: Convex-concave (meniscus) lenses can be either positive or negative, depending on the relative curvatures of the two surfaces. A negative meniscus lens has a steeper concave surface and will be thinner at the centre than at the periphery.
Rapid Rectilinear Lens (RR Lens): The Rapid Rectilinear is a lens that is symmetrical about its aperture stop with four elements in two groups. It was introduced by John Henry Dallmeyer in 1866. The symmetry of the design greatly reduces radial distortion.

Photodetector - sensors of light or other electromagnetic energy
Infrared - electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 mm
Light-emitting diode - two-lead semiconductor light source that resembles a basic pn-junction diode, except that an LED also emits light
Thermal imaging camera - type of thermographic camera used in firefighting, by rendering infrared radiation as visible light, such cameras allow firefighters to see areas of heat through smoke, darkness, or heat-permeable barriers
