Especially for underwater or when working with suspensions, the amount of scattered light is very high, so 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. Connected to the ULM-500.

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