What optical instrument are used in camera?
convex lens
A camera uses a convex lens to make a reduced image of an object.
Why is a camera called an optical instrument?
The light rays fall on the lens of the camera and then get focused at one point. This results in the formation of a sharp image. A camera is an optical instrument that makes use of a convex lens. Hence, option A is the right answer.
What are the name of optical instruments?

- Magnifying glasses.
- Microscopes.
- Telescopes.
- Slide projectors.
- Cameras.
- The eye.
Which is an optical instrument?
Optical instruments are the devices which process light wave to enhance an image for a more clear view. The use of optical instruments, such as a magnifying lens or any complicated device like a microscope or telescope, usually makes things bigger and helps us to see in a more detailed manner.

What is CMM and OMM?
CMM, coordinate measuring machine; MPG, monomial parameters gauge; OMM, on-machine measurement.
What is the difference between CNC and CMM?
A CMM machine can be either manually operated or controlled by a computerized unit. CNC stands for computerized numerical control. In CNC manufacturing, the machines used in metalworking or other machining operations are controlled by the automation system.
What is optical photography?
optical image, the apparent reproduction of an object, formed by a lens or mirror system from reflected, refracted, or diffracted light waves. There are two kinds of images, real and virtual.
What is optical CMM?
An optical CMM, similar to optical comparators and measuring microscopes, is a non-contact instrument that uses images to perform measurements. Optical CMMs are also known as CNC image measuring machines, where “CNC” is an abbreviation of Computer Numerical Control.
What is OMM measurement?
Optical measurement machine (OMM) refers to 2-axis non-contact measuring system that uses image processing technology with metrology software to analyze images obtained through optics or camera (or both) on the sample placed on moving stage with illuminations.
