Description
The LSG-1890B/LSG-1800A goniophotometer is an automated photometric instrument designed for precise measurement of luminous intensity distribution through controlled rotation of light sources. This system incorporates a constant temperature photodetector, precision Japanese servo motors, and German-engineered angular encoders to ensure measurement accuracy and repeatability. It is engineered for industrial laboratory applications requiring comprehensive photometric data acquisition for various luminaire types including LED fixtures, HID lamps, and fluorescent lighting systems.
