"A lens is an optical device which transmits and refracts light, converging or diverging the beam. A simple lens consists of a single optical element. A compound lens is an array of simple lenses (elements) with a common axis; the use of multiple elements allows more optical aberrations to be corrected than is possible with a single element. Lenses are typically made of glass or transparent plastic. Elements which refract electromagnetic radiation outside the visual spectrum are also called lenses: for instance, a microwave lens can be made from paraffin wax.
The variant spelling lense is sometimes seen. While it is listed as an alternative spelling in some dictionaries, most mainstream dictionaries do not list it as acceptable." [Lens (optics). Wikipedia]

Physics solution extends ConceptDraw PRO software with templates, samples and libraries of vector stencils for drawing the physical illustrations, diagrams and charts.
The vector stencils library "Computer peripheral devices" contains 18 clipart images of computer peripheral devices and equipment for drawing network diagrams.
"A peripheral is a device that is connected to a host computer, but not an integral part of it. It expands the host's capabilities but does not form part of the core computer architecture. It is often, but not always, partially or completely dependent on the host.
There are three different types of peripherals:
(1) Input, used to interact with, or send data to the computer (mouse, keyboards, etc.).
(2) Output, which provides output to the user from the computer (monitors, printers, etc.).
(3) Storage, which stores data processed by the computer (hard drives, flash drives, etc.)" [Peripheral. Wikipedia]
The clip art example "Computer peripheral devices - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.
