On‑axis CCD
High imaging efficiency by moving the galvo position;
High positioning accuracy, small field of view;
When used with our galvo control software, it automatically achieves large‑range, high‑precision galvo distortion correction.
Technical Specifications
| Parameter | On‑axis | Pseudo on‑axis |
|---|---|---|
| Laser Wavelength | 355nm, 532nm, 1064nm | 355nm, 532nm, 1064nm, 10.6μm (transmissive) |
| Spot Size | 10-30mm | 10-30mm |
| Camera | Selected according to sample (CMOS camera) | |
| Lens | Selected according to sample | |
| Effective Field of View | < Φ30mm | 170×170 (F254 field lens) |
| Effective Working Area | 300×300 (F420 field lens, after high‑precision calibration) | 170×170 (F254 field lens) |
| Positioning Accuracy | ±0.02mm | ±0.04mm |
| Parameter | On‑axis | Pseudo on‑axis | Off‑axis |
|---|---|---|---|
| Efficiency | High | High | Low |
| Positioning Accuracy | High | Depends on lens | Depends on lens + motion platform accuracy |
| Field of View | Small | Custom design, generally matches marking area | Flexibly designed based on requirements |
| Image Quality | Slightly worse than pseudo on‑axis (affected by field lens) | Good | Excellent |
| Flexibility (Lens & Light Source) | Limited choices | Moderate choices | Arbitrary combination |
Note: These three solutions complement each other; choose the right one based on your project.
