LBTEK frequency-stabilized He-Ne lasers are single longitudinal mode, high-stability lasers with a coherence length of over 300 m. Their exceptional stability and high polarization extinction ratio make them widely used in precision metrology, spectroscopic standards, and other high-accuracy applications.
Designed for strong adaptability and reliable operation, these He-Ne lasers are plug-and-play with long service lifetimes. When paired with the HM-V50 V-mount holder, they can be easily integrated into experimental optical setups.
