Technical Specifications
| Specification | Value |
|---|---|
| Wavelength | 630 - 640nm (red) |
| Output power | 0.9mW |
| Laser class | Class II |
| Beam divergence | Approximately 1 millirad |
| External modulation input | 3.5mm jack socket, rear panel (digital or analogue) |

How It Is Used
Switched to the internal generator, the laser sends out short pulses so the time taken for light to travel a measured distance can be found, which is the basis of speed of light experiments. Alternatively, an external digital or analogue waveform can be fed into the jack socket to modulate the beam.
