Polarized He-Ne Laser
The EL series He-Ne high stability polarization laser is engineered to fulfill stringent demands for polarization, low noise, stability, and longevity in precise laser measurements.
The key component adopted in the EL series He-Ne high stability polarization laser is international advanced laser assembly. Closed cathode design style can quickly and uniformly release energy distribution through the whole laser diode, ensuring advantageous thermal stability, including stability of the laser spot and the power. The design of the field concentrator guarantees to excite the discharge in milliseconds applying the initial voltage. All strong points of the internal mirror in a hard-seal package, small physical size, and low noise ensure higher stability, longer life, and better performance.
The laser diode portion of the EL series He-Ne high stability polarization laser will be easily connected to the working platform by metric thread holes, allowing adjustment of high-accuracy height, pitch, and swing on left and right, making it easy to use.
