Multimodal and modular apparatus for optical measurements of a material sample

A multimodal and modular optical apparatus for acquiring optical data from a material sample and generating at least one parameter for characterization of the material sample, the apparatus comprising:

• a principal system comprising:
• a main body defining a sample receiving space and at least one cartridge-receiving space, wherein the sample receiving space is sized and shaped for receiving the material sample;
• and
• at least one cartridge being sized and shaped for reversible insertion in the at least one cartridge-receiving space, wherein the at least one cartridge comprises:
• an emitter configured to emit electromagnetic radiations propagating to the material sample, and/or a receiver configured to receive and measure electromagnetic radiations from the material sample in response to the emitter, thereby generating the optical data, and
• a cartridge connector configured to communicate the optical data;
• and
• a control and processing unit being in data communication with the at least one cartridge via the cartridge connector to receive the optical data, and further generating the at least one parameter for characterization of the material sample from the optical data.
