Introduction
Think REO is a leading manufacturer of high-performance Helium-Neon (HeNe) lasers, specializing in applications such as confocal microscopy, ellipsometry, particle counting, and food sorting. The company distinguishes itself by polishing and coating its own laser mirrors in-house, ensuring high reflectivity and minimal scatter and absorption.

Product Features
The Green (543 nm) Cylindrical Helium-Neon Lasers are characterized by their long lifetime, superior beam pointing stability, excellent power stability, and high thermal stability.

Specifications

• Optical: Minimum output power ranges from 0.5 mW to 2 mW, with a maximum of 5 mW. The lasers exhibit multimode and TEM00 mode structures with beam diameters ranging from 0.64 mm to 1.62 mm and beam divergence from 0.84 mrad to 4.02 mrad.
• Polarization: Options include random and linear polarization with a ratio greater than 500:1.
• Electrical: Starting voltage is less than 10 kVDC, with operating voltages between 1800 VDC and 3200 VDC. The recommended power supply varies by model.
• Mechanical: The lasers weigh between 600 grams and 750 grams, with shock resistance of 15 g for 11 msec. Operating temperatures range from -20°C to +70°C, and non-operating temperatures from -40°C to +80°C.

Safety and Compliance
The lasers are classified as Class 3R laser products, indicating that exposure to the beam should be avoided.
