Light sources
Lasers
Laser: connected with fiber
- Description: laser connected with fiber to collimator tube.
- Class: IIIb (3B), 5 mW. Note: when used with the collimator tube the effective output is below class II, i.e. no risk for the eye.
- Wavelength: 635 nm.
Laser: stick
- Description: black, long thick stick, He-Ne laser.
- Class: II, 0.95 mW.
Laser: small tube
- Description: small laser powered by 4.5 V flat battery.
- Class: IIIa (3R), about 4.5 mW.
