This 35mW Helium-Neon (He-Ne) Laser Power Supply is a high-performance, precision DC driver designed to excite and regulate 35mW He-Ne laser tubes operating at 633 nm (red wavelength). As one of the most powerful commercial He-Ne power supplies available, it is ideal for demanding applications including metrology, flow cytometry, confocal microscopy, particle measurement, and interferometry.
The power supply features universal AC input (110-240 VAC, 50/60 Hz), comprehensive protection circuits, and stable current regulation to ensure consistent 35mW optical output. It is compatible with major He-Ne laser head models including Newport N-LHP-928, N-LHP-928J, and Pacific Lasertec 25-LHP-928 series.
