| Type | |
| Red semiconductor laser; Wavelength | |
| 655 nm (visible light); Laser Class | |
| Class II (FDA CDRH 21CFR PART1040.10); Output | |
| 0.95 mW; Spot diameter (at reference distance) | |
| Approx. 120 x 1,700 µm 0.0047" x 0.0669"; Linearity | |
| ±0.05 % of F.S. (F.S.= ±40 mm ±1.57" ) *3; Repeatability | |
| 0.5 µm 0.000020" *4; Sampling frequency | |
| 20 / 50 / 100 / 200 / 500 / 1,000 µs (Selectable from 6 levels); LED display | |
| Near the center of the measurement | Green lights Within the measurement area: Orange lights Outside the measurement area: Orange flashing; Temperature characteristics |
