    摘要： An inspection device comprises a camera assembly including an objective lens that captures and collimates light associated with an object being inspected, an image forming lens that forms an image of the object based on the collimated light, and a camera that renders the image. The camera assembly defines a focal point distance from the objective lens that defines a focal point of the camera assembly. The inspection device comprises an optical sensor positioned to detect an actual distance between the objective lens and the object, an actuator that controls positioning of the objective lens to control the actual distance between the objective lens and the object, and a control unit that receives signals from the optical sensor indicative of the actual distance. Control signals from the control unit can control the actuator to adjust the actual distance such that the actual distance substantially equals the focal point distance.

    摘要： A rotary spectrometer including a plurality of input ports. Each input port may be arranged to receive an optical waveguide carrying electromagnetic radiation. The spectrometer also includes a plurality of optical bandpass filters, which are housed on a first body that rotates under the control of a motor so that each optical bandpass filter may be brought into alignment with each input port. Further, the spectrometer includes a plurality of detector circuits disposed on a second body that rotates with the first body. Each detector circuit is optoelectrically coupled to one of the plurality of optical bandpass filters, thereby resulting in each detector circuit being dedicated to responding to a range of wavelengths determined by the bandpass filter to which it is optoelectrically coupled.
