Flicker & Glare Test
LLD-217 Luminance Measurement System
Wide dynamic range , high repeatability
LLD is specifically designed for on-site measurement of tunnel lighting and road lighting; it enables easy installation. With exceptional imaging quality, high accuracy, high repeatability, and intuitive operation, it is widely used in road lighting, tunnel lighting, architectural lighting, and related fields.
Features
- 1.Adopts a professionally engineered optical system featuring superior imaging performance, fast measurement speed and easy operation.
- 2.Equipped with a dedicated image sensor and high-performance cooling architecture to deliver highly stable measurements.
- 3.Advanced dark-current control technology delivers high test sensitivity and ensures stable measurement at low luminance levels.
- 4.Feature-rich software supports flexible ROI selection of arbitrary size and shape; it enables luminance distribution and iso-luminance contour analysis for lighting scenes, alongside calculations of average, maximum, minimum luminance, min/max ratio and min/average ratio.
