The ALSC-21-M-15 Ambient Light Chamber is a test apparatus with thousands of ultra-bright white LEDs, allowing a multi-directional wash of light over a device under test. The system can be expanded to include near infrared wavelengths. The chamber is interfaced with a host system via Ethernet.
Light can be varied from very dim (5-10 lux) to daylight (80,000 lux). This allows testing the practical range of intensities reportable by embedded ambient light sensors in common consumer electronics.
