A fiber spectroscopic probe that can be mounted directly above the objective lens of a standard microscope to add a spectroscopic function to the microscope. The fiber spectroscopic probe only consists of a minimum number of optical components and is compact enough to induce minimum alteration to the optical path of the microscope.

Fiber spectroscopic probe mountable on a microscope

A fiber spectroscopic probe that can be mounted directly above the objective lens of a standard microscope to add a spectroscopic function to the microscope. The constructed microscope with fiber spectroscopic probe is suitable for micro-sampling, Raman analysis, as well as fluorescence analysis and can be easily reconfigured for different excitation/detection wavelengths. The fiber spectroscopic probe only consists of a minimum number of optical components and is compact enough to induce minimum alteration to the optical path of the microscope.

A light emitting diode (LED) signaling apparatus for navigational aids is provided. The signaling apparatus comprises a plurality of high intensity LEDs with their output beams individually controlled by high precision optical beam transformers. The transformed LED beams are mixed in a predetermined manner by controlling the relative position, angular orientation, and other parameters of the LEDs to produce a desired illumination pattern.

Optical signaling apparatus with precise beam control

In a laser based curing apparatus, the acts both as the curing light and the excitation source for a Raman spectroscopic sensor. The spectroscopic sensor provides real-time, in situ, non-invasive curing status monitoring via Raman spectroscopy. The spectroscopic information can be further used to control the operation parameters of the laser to achieve the optimum cure result.
