Var-XRCT-K61C33
The Var-XRCT-K61C33 AR glasses luminance & chromaticity meter is a dedicated optical instrument for measuring the virtual-image luminance, chromaticity anduniformity of near-eye displays (NED). It couples and receives light at the eyebox in the same way as the human pupil and a single exposure outputs full-frame luminance distribution, color coordinates, uniformity, contrast, MTF, distortion,ghosting and other parameters. It is a key inspection tool taking Micro-LED, optical engines, waveguides and AR glasses optical modules from R&D to mass production.

Features

Customized Optical Architecture for XR Inspection
●In-house Xr-Y-Z-Xb four-color filter system built for XR inspection. Entrance pupil diameter is selectable with a front air stop, and both straight-barrel and 120°folded-prism lens options are offered; the large 120° fold avoids interference with AR glasses temples, solving the common problem of lens interference.
●Fully compatible with waveguide and complete AR glasses testing. Lens MTF approaches the diffraction limit. Manual and motorized focusing models are available; motorized focusing covers -6 D to +4 D, meeting test requirements for different VID virtual image distances.

Comprehensive Inspection Covering the Full AR Optical Chain
●Dedicated AR display inspection algorithms, tailored to the small pixel size, high luminance and self-emission of Micro LED, precisely identify pixel-level bright/dark spots and cluster defects with low false-call rates and high repeatability,supporting automatic defect classification and marking.

Full In-House Capability + Standardized Calibration System
●End-to-end in-house development color filters, NED optical lenses, mechanical structure, hardware circuitry and test-algorithm software are all developed by internal teams, enabling fast hardware and algorithm customization to customer requirements, including custom CMOS specifications and custom inspection solutions.
●Standardized calibration chain: flat-field FFC, distortion, dark-field and color-filter response are fully calibrated before shipment the instrument outputs a complete OQC report for direct use in R&D verification and factory quality records.

Wide Range, Fast Switching, Full Luminance Coverage
●A multi-position ND attenuation wheel (ND0-ND3) gives a luminance test span of 0.1 nit to 2,000,000 nit, fully covering AR optical engines from dark state to high brightness; filter-wheel switching takes ≤0.5 s, effectively cutting single-station cycle time and improving overall test takt.
