LHJ-1F Offset Frequency Laser Standard
LHJ-1F is a high-precision offset frequency laser standard designed for the calibration and comparison of helium-neon lasers with a wavelength of 632.8 nm. The system is based on the LJSC-03-11 platform, where the absolute laser frequency is determined by an iodine vapor cell and used as feedback for stabilizing a higher-power laser. The device provides the same frequency accuracy and stability as the LJSC-03-11, while offering helium-neon tube output power of up to 1 mW.
The higher-power laser tube is synchronized with the stabilized helium-neon reference tube, and the offset value can be adjusted by the user over a wide range without degrading the laser frequency accuracy. LHJ-1F is a unique laboratory solution featuring automatic absorption peak detection, graphical display of results, and remote control from a PC. Thanks to its robust and compact design, the unit is suitable for both laboratory and field applications, including precision measurements, laser spectroscopy, and other high-accuracy tasks.
