Mer-AR70DFF
The Mer-AR70DFF is a straight-barrel full-frame AR inspection lens designed for optical performance inspection and production of AR devices and modules. Especially suited to inspection systems for high-PPD, wide-FOV ARoptical engines or AR glasses, it provides a high-precision, high-efficiency solution for AR R&D, production and QC, with the following core advantages:
●Full-frame ultra-HD AR inspection, ultra-low stray light, high transmittance
●High PPD of 150, high resolution
●FOV up to 70°, customizable auto-focus
Features
AR detection lens Mer-AR70DFF has many core technical advantages:
Ultra-HD PPD
Designed for the ever-increasing pixel counts of AR optical engines, this lens meets both R&D testing and mass-production inspection needs of ultra-HD AR optical engines.
High Resolution
High resolution of 0.4 @ 100 lp/mm simulates human-eye imaging more sharply for better image detail and quality.
Optional Auto-Focus
To meet equipment-integration needs, an optional auto-focus module is available, saving R&D time and helping bring products to market faster.
Compact size, Space-Saving
Smaller than industry benchmarks, the lens strikes the best balance between performance and size: while meeting test requirements it minimizes dimensions for easy alignment and installation and more flexible inspection.Interchangeable stops suit different scenarios.
