He-Ne laser BEM-5025 consists of power supply and fully closed cavity He-Ne laser tubes. The output wavelength is 632.8nm and the power is less than 5mW. It can be used for laser pointer and optical collimation because of its stable performance.
This He-Ne laser has non-polarized laser and linear polarization for users to choose. It can produce linearly polarized laser by adding Brewster window laser tube ends. The polarization is better than 200: 1.
We provide professional fixture and base of the He-Ne laser for fixing and regulating.
