RSHN-250 He-Ne Laser works at 632.8nm, which is idea for holography, confocal microscopy,
spectroscopy, actinochemistry, biochemistry, laser iatrology, scientific research and teaching area. It
features Singlemode output, higher power, good stability, long lifetime.
RSHN-250 is composing of laser head and base, this laser head includes laser tube and power supply.
Laser discharging tube is made in twice modeling, which features precise size, higher single mode output
power.
Power supply is switchable high-voltage power supply, which features lightweight, good reliability and
adaptability.
