2. Core Technical Advantages of SunFlaser
2.1 Genuine Eye Safety
Notably, the entire series uses 1535nm Er:Glass lasers. Specifically, the laser energy is fully absorbed by the cornea and does not reach the retina. Therefore, it meets Class 1 eye‑safe standards. As a result, there are no usage restrictions in open environments.
2.2 Military‑Grade Reliability
Additionally, all products have passed rigorous tests, including high‑low temperature cycling, shock, and vibration. Moreover, they maintain stable output from ‑40°C to +65°C. Thus, they are reliable in vehicle‑mounted, airborne, and field extreme environments.
2.3 Full Energy Range Coverage
Notably, pulse energy ranges from 20μJ to 10mJ, while repetition rates vary from 10Hz to 2kHz. Hence, they meet diverse application needs. For instance, short‑range handheld, medium‑range inspection, and long‑range detection are all covered.
