Overview
The Focusing Lens concentrates the laser beam into a fine spot to achieve the high energy density needed for engraving and cutting. R1 ships with the Short Focal (standard) lens, which has the smallest spot size and the best detail performance.
- Medium Focal (M) — a good balance of precision, speed and cutting capability, well suited to most everyday applications.
- Long Focal (L) — longer depth of field and stronger cutting ability, well suited to cutting thicker materials.
Cutting capacity by lens
| Lens | Spot size | Max. cut (black walnut / acrylic) |
|---|---|---|
| Short focal (included with R1) | Ø0.11 mm | 15 mm / 20 mm |
| Medium focal | Ø0.17 mm | 18 mm / 20 mm |
| Long focal | Ø0.19 mm | 18 mm / 20 mm (faster than medium at the same thickness) |
