A confocal microscope uses fluorescent or reflected light obtained by irradiating a plurality of beam spots to a sample so as to observe the sample. The control circuit has an input for receiving actuator commands and has an output connected to the motor to control operation of the motor. The body includes an energy absorbing frame structure having cross members, forward, central and rearward side members, and a pair of A-columns and B-columns. The characteristic and positional imaging data of the food items may be stored or communicated to a display monitor for the user to view. The composition can be used as a catalyst per se or as additive catalyst to a conventional catalyst and is especially suitable for enhancing yields of light olefins, and particularly ethylene, produced during conversion processes.
