Description
Laser Cutting Engraving Marking 35mW Hene Laser Power Supply 110-220V
Product Overview

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.

Key Features
  • 35mW Output Support: Specifically designed for high-power He-Ne laser tubes up to 35mW optical output
  • Universal AC Input: Operates on 110-240 VAC, 50/60 Hz for worldwide compatibility
  • Stable Current Regulation: Maintains consistent discharge current for stable optical output
  • Comprehensive Protections: Over-voltage, over-current, short-circuit, and open-circuit protection
  • Compact Design: Standard 1U-style enclosure for easy rack or benchtop integration
  • Long Lifetime: Supports He-Ne tube lifetimes exceeding 20,000-40,000 hours
