632.8nm HeNe laser 1.2mw

Our 1.2mW red (632.8nm) cylindrical HeNe lasers are designed in a tube, which makes them easy to install in almost all optical systems. The lasers of these lasers are linearly polarized light (200:1) or randomly polarized. The linearly polarized light is polarized in the vertical direction relative to the cable at the rear of the laser housing, and comes with an external power supply and power cord. The laser of the B-type intracavity HeNe laser is separated from the power supply. Turning the laser power switch will not affect the adjusted optical path. The laser is covered with an alloy aluminum tube with a plastic-sprayed surface. This makes the laser sturdy and beautiful. The power supply uses a switching power supply and a metal housing. The power housing is grounded, and the laser is connected to the power supply with a silicon high-voltage wire. Our HeNe lasers are suitable for mainland China and are equipped with a domestic mains socket, which can be plugged in and used.

Note:

Some experiments (such as laser interference, holography, etc.) require splitting a laser beam into two laser beams. If you choose randomly polarized laser beam splitting, the light intensity of the two laser beams after splitting is unstable. If you choose linearly polarized laser beam splitting, the light intensity of the two laser beams after splitting is much more stable. The larger the extinction ratio of polarization, the more stable the light intensity of the two laser beams after splitting. The better the experimental effect.
