Optical train
Encyclopedia
Optical train also called optical assembly is the arrangement of lenses
to guide line of sight
and lasers.
The position and angle of lenses are adjusted to guide a laser
through the path required.
Lens (optics)
A lens is an optical device with perfect or approximate axial symmetry which transmits and refracts light, converging or diverging the beam. A simple lens consists of a single optical element...

Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of photons. The term "laser" originated as an acronym for Light Amplification by Stimulated Emission of Radiation...
