Especially under water or when working with suspensions, the amount of scattered light is very high, so that a spherical sensor should be used. The US-SQS sensor uses a plastic diffuser to obtain an angular response error of less than ± 5% from -100° to 100° angle.

For photosynthesis research, sensors with spectral and directional sensitivity relevant for plants are required.

US-SQS Sensor

Design of sensor: 3.7 mm diameter white plastic diffusing sphere connected via internal 2 mm plastic light guide with detector
