He-Ne / He-Cd Laser

■ He-Ne Laser

We offer an extensive selection of CE compliant 632.8 nm (red) Helium-Neon (HeNe) Lasers with powers from 0.8 mW to 22.5 mW from stock. In addition to the applications listed to the right, HeNe lasers are widely used in education and as alignment tools due to their excellent beam quality and gas discharge laser characteristics. Depending upon the model, the output beam is either linearly polarized or randomly polarized (unpolarized). The polarization state of a randomly polarized HeNe changes on nanosecond timescales; when averaged over time, the light emitted from these lasers appears randomly polarized. However, any polarization optics in the path (intentional or unintentional) can cause large variations in the output power. Only polarized lasers should be used in applications that involve polarization optics.

■ He-Cd Laser

At KIMMON KOHA we pride ourselves on the quality of our laser systems. Our goal is to provide the highest quality leading edge HeCd lasers in the world to our customers. To achieve this goal we build, produce, assemble, and process almost everything for our HeCd lasers in-house. Although this is more expensive than subcontracting, this allows us to control the whole manufacturing process. One of the unique capabilities of the KIMMON KOHA production system is our ability to process raw quartz from our own quartz mines and produce our HeCd laser tubes in-house. These capabilities translate into higher quality products for our customers.
