The invention relates to a measuring device for multispectral measuring of products, such as vegetables and fruit, a sorting system provided therewith and a method therefor. A measuring device according to the invention comprises a frame provided with transport means for transporting the products, a camera system provided with at least one light source and at least one camera for recording an image at a frequency or frequency spectrum, and a controller operatively connected to the camera system for controlling the camera system, wherein the controller is provided with a data processing system and detection system.

An approach for controlling light exposure of a light sensitive object is described. Aspects of this approach involve using a first set of radiation sources to irradiate the object with visible radiation and infrared radiation. A second set of radiation sources spot irradiate the object in a set of locations with a target ultraviolet radiation having a range of wavelengths. Radiation sensors detect radiation reflected from the object and environment condition sensors detect conditions of the environment in which the object is located during irradiation. A controller controls irradiation of the light sensitive object by the first and second set of radiation sources according to predetermined optimal irradiation settings specified for various environmental conditions. In addition, the controller adjusts irradiation settings of the first and second set of radiation sources as a function of measurements obtained by the various sensors.
