Developed by Bausch & Lomb and launched in 1953, the Spectronic 20 was the first low-cost spectrophotometer. [5] It rapidly became an industry standard [7] due to its low cost, durability and ease of use, [8] and has been referred to as an "iconic lab spectrophotometer". [9] Approximately 600,000 units were sold over its nearly 60 year ...
John Jacob Bausch (born Johann Jakob Bausch; July 25, 1830 – February 14, 1926) was a German-American maker of optical instruments who co-founded Bausch & Lomb (with Henry Lomb). Over six decades he transformed his small, local optical shop into a large-scale international enterprise, pioneering the American optical industry.

The stereo, stereoscopic or dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it. The instrument uses two separate optical paths with two objectives and eyepieces to provide slightly ...
Diagram of a simple microscope. There are two basic types of optical microscopes: simple microscopes and compound microscopes. A simple microscope uses the optical power of a single lens or group of lenses for magnification. A compound microscope uses a system of lenses (one set enlarging the image produced by another) to achieve a much higher ...
