LSG-1200A — LISUN Goniophotometer

The LSG-1200A compact goniophotometer measures luminous intensity distribution, intensity data, spread angle and other parameters for chip LEDs, LED modules, LED spotlights and all lights with a beam angle no greater than 180 degrees. The instrument includes its own dark chamber.

Measurement outputs include Illuminance at a Distance, Photometric (luminous intensity distribution), and Isocandela diagrams. The system automatically measures beam angles including standard half-intensity angle, plus 1/4, 3/4 and 1/10 intensity angles.

Measured data is output in IES format and compatible with DiaLux. The detector has a test range of 0.1–30,000cd at Class A accuracy. Horizontal and vertical rotation are fully automated (0–360° and -90° to +90° respectively). Can interface with LISUN Digital Power Meters and AC/DC Power Sources.
