Features
The AR detection lens Mer-FtheC33 has many core technical advantages:
Multi-Scenario: AR Inspection /AA/Micro LED RGB Bonding
Designed for AR module and full-unit inspection, active alignment (AA) and RGB bonding, it surpports high-precision color imaging, eliminates chromatic aberrationinterference, ensures true and consistent AR display color,improves inspection reliability and speeds RGB light-source bonding alignment with pixel-level accuracy.
34 mm Extra-Long Working Distance
A 34 mm working distance avoids collision between the lens and precision components (e.g. Micro LED micro-projection systems), suits complex alignment setups, and keeps inspection safe and flexible.
365 Ultra-High PPD, Diffraction-Limited Resolution
Diffraction-limited resolution combined with 365 PPD (pixels perdegree) captures detail beyond the limit of the human eye, meeting micron-level defect inspection needs of high-definition AR products(e.g. waveguides, Micro LED bonding)
Compact structure with Air stop
Optimized lens volume balances performance and portability; a proprietary air-stop design plus interchangeable 4-6 mm physical stops flexibly meet the optical-path control needs of AR inspection, AA and RGB bonding, improving inspection and production efficiency.
