ACCU-GOLD LIGHTMETER

Product catalog summary

Overview
The Radcal Accu-Gold Lightmeter is a diagnostic tool used in imaging environments to measure the luminance and uniformity of back-lighted display screens, as well as the illuminance of ambient light on the screen surface. It provides measurements in metric (SI) units.

Key Features

Multi-function connectivity for easy integration with computers.
Measures both surface luminance and ambient light with cosine-corrected illuminance.
Unlimited storage and data recall capabilities.
Accurate evaluation of ambient light sources regardless of incidence angle.

Specifications

Type: Portable, hand-held lightmeter designed as an accessory to the Accu-Gold system.
Measuring Capability: Luminance in candela per square meter (cd/m²) and illuminance in lux.
Light Sensor: Silicon photo-diode with an optical filter simulating the human eye's photopic response.
Luminance Range: 0.05 to 50,000 cd/m².
Illuminance Range: 0.05 to 50,000 lux.
Luminance Aperture: 10 mm diameter measuring field with a 1:1 focusing lens.
Calibration Uncertainty: Less than 3% of value or 0.05, whichever is greater, relative to Illuminant A.
Calibration Traceability: Traceable to NIST and international standards.
Cosine Response: Less than 2.5% based on the CIE f2 Test.
Resolution: 0.01 cd/m² and 0.01 lux.
Photopic Response: Less than 3% deviation from the 1931 CIE photopic curve standard.

Components

Accu-Gold Lightmeter with Accu-Gold Digitizer.
Luminance Adapter and Illuminance Base Sensor.

ACCU-GOLD LIGHTMETER KEY FEATURES AND BENEFITS: TYPE - Portable, hand-held lightmeter for the measurement of display surface luminance and ambient light cosine-corrected illuminance. Designed only as an accessory to the Accu-Gold. MEASURING CAPABILITY - Measures luminance level in candela per square meter (nits) units and ambient light level in lux units. LIGHT SENSOR - The base unit of the light meter contains a silicon photo-diode that can be exposed to ambient light through an optical filter, which very accurately simulates the spectral response of the human eye’s photopic response in order...
