Optical tweezers ( originally called " single-beam gradient force trap ") are scientific instruments that use a highly focused laser beam to provide an attractive or repulsive force ( typically on the order of piconewtons ), depending on the refractive index mismatch to physically hold and move microscopic dielectric objects.

Optical traps are very sensitive instruments and are capable of the manipulation and detection of sub-nanometer displacements for sub-micrometre dielectric particles.

Optical engineers design components of optical instruments such as lenses, microscopes, telescopes, and other equipment that utilizes the properties of light.

Optical engineering metrology uses optical methods to measure micro-vibrations with instruments like the laser speckle interferometer or to measure the properties of the various masses with instruments measuring refraction.
