LSW-10 Helium Neon, optical He Ne Laser light 

Helium Neon/He Ne laser with external power LSW-10

Working voltage: 1800-2000V

Working current: 5-6 mA

Power stability: + - 5%

The Outside of the mouth of light spot diameter: 1.2 mm

Divergence Angle: 2.0 mard

Pattern: TEM00

Wavelength: 632.8 nm

Power supply voltage: 50 Hz  AC 220 v

These are regular technical parameters

Because each of the laser tube internal resistance is not the same .So  an adjustable resistance is set to  adjust the working current.
