Product Overview

The Uniformity Analyzer UA-10A, developed by TechnoOptis (formerly Topcon Technohouse Corporation), is a high-speed, in-line inspection instrument designed for stable and precise measurement of luminance and chromaticity uniformity in displays and lighting applications. It supports rapid measurement cycles as fast as 0.98 seconds and is suitable for various display types including OLED smartphones, automotive speedometers, VR displays, TVs, and signage.

Key Components and Accessories

• Main unit: UA-10A body
• AC adapter
• Carrying case
• Standard software: Colorimetric Image Software CI-100
• Optional software: BlackMURA (for European standards)
• SDK for external control (standard accessory)
• Optional ND filters: 1% and 0.01% for high luminance measurement
• Tripod 5N and tripod head (optional)
• LAN (GigE) cable for PC connection

Measurement Capabilities and Specifications

The UA-10A supports three interchangeable fixed focal lenses:

• UA-10AS (Standard lens, f=12mm)
• UA-10AW (Wide lens, f=6.5mm)
• UA-10AT (Telephoto lens, f=50mm)

Measurement ranges vary by lens and ND filter usage:

• No ND filter: 0.1 - 80,000 cd/m²
• ND filter 1%: 10 - 8,000,000 cd/m²
• ND filter 0.01%: 1,000 - 800,000,000 cd/m²

The device uses a 2.3-megapixel CMOS image sensor (1920×1200 pixels, 12-bit data) with high accuracy:

• Luminance accuracy: ±2%
• Chromaticity accuracy: ±0.003
• Repeatability and stability within ±1-3% depending on conditions

Software and Analysis Functions

The standard Colorimetric Image Software CI-100 enables:

• Center and four-corner luminance and chromaticity comparison
• Resolution and focus calculation
• Data collection, storage, and display

The optional BlackMURA software provides advanced display quality analysis compliant with DFF (Deutsche Flat Panel Display Forum) standards, including:

• Mura evaluation of luminance and chromaticity for LCDs, OLEDs, QDs, micro LEDs
• Emission distribution analysis for automotive panels and LED/OLED lighting
• Various evaluation modes: pseudo color, standard/random/auto spot, cross section
