LGN – 302

Gas laser LHN-302 atomic stabilized continuous mode operating on two or any of two orthogonally polarized radiation components is intended to be used as a source of coherent radiation resistant to mechanical and climatic influences in interferometric devices for monitoring and measuring the values of linear displacements built in processing equipment in precision engineering, as well as for solving scientific and technical problems related to the control of physical quantities expressing the length.

Continuous operating gas lasers are designed to be used as a source of coherent radiation in various equipment, for monitoring optical elements, for monitoring semiconductors, for gas analysis, and for health care purposes.
