LJSC-03-11 Frequency Laser Standard

LJSC-03-11 is a high-precision frequency laser standard designed for comparison and calibration of helium-neon lasers with a wavelength of 632.8 nm. The laser stability is achieved by using reference frequencies based on atomic iodine isotope transitions. The unit is intended for metrology, calibration laboratories, scientific research, and service centers where accuracy, repeatability, and long-term stability are essential.

The unique design of the system provides automatic detection of absorption peaks and displays results on an integrated graphical VFD display. Thanks to its compact design, high level of automation, and no need for regular calibration, LJSC-03-11 is a convenient and reliable solution for precision measurements and verification of laser equipment.
