Two sides, two sensors, multiple functionalities

Two Sides, Two Sensors

Accurate exposure at the speed of a flash

The sensor behind the dome is a fast-response Silicon photo diode. It responds to light even in near-darkness and accurately measures exposure for the Photo ambient and Cine/video functionalities. Capture flash for those frozen-moment images even at 1/40,000s. 
Fast response Photo Diode

Photo Ambient Exposure / Flash / Cine-Video

Measuring range: EV -4 to 20 at ISO 100
Accuracy: +/- 0.1 EV
Light receptor: fast-response Silicon photo diode, CIE spectral luminous efficiency
Hemispherical Diffuser, Cardioid-type responses
Flash duration measurement: 1/40,000 - 1/250 s 

There’s more to colour than meets the eye

The sensor on the flat side is a True Color Sensor with CIE 1931 Color standard Human eye perception, one of the most accurate sensors on the market. Along with color temperature and chromaticity, Illuminance is also measured with this sensor because of the cosine type response.
