An illustration of some of the optical devices available for laboratory work in England in 1858. An optical instrument is a device that processes light waves (or photons), either to enhance an image for viewing or to analyze and determine their characteristic properties. Common examples include periscopes, microscopes, telescopes, and cameras ...
Medical optical imaging is the use of light as an investigational imaging technique for medical applications, pioneered by American Physical Chemist Britton Chance. Examples include optical microscopy , spectroscopy , endoscopy , scanning laser ophthalmoscopy , laser Doppler imaging , optical coherence tomography , and transdermal optical imaging .

Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation. [ 1 ] Electro-optics is often erroneously used as a synonym, but is a wider branch of physics that concerns all interactions between light and electric fields , whether or not they form part of an ...
