Profile: Ocean Optics, Inc. designs, manufactures, and supplies optical sensing and spectroscopy products. Our product line includes spectrometer, sensors, optical fibers, probes and oem solution. Our ocean optics optical transmittance spectrophotometer (OTS) is ideal for both in-line and in-lab applications where transmittance accuracy (to +/- 1.0%) and precision (+/- 0.1%) are critical. Common applications include measurement of optical coatings, windows and filters, and glass and plastic components. Our USB2000-FLG is a high-sensitivity spectrofluorometer that is preconfigured for fluorescence applications from 380-1050 nm. The USB2000-FLG detector window is fitted with an L2 detector collection lens. This cylindrical lens increases the spectrometer's light-collection efficiency and reduces stray light. The L2 is especially useful with a large-diameter fiber for low light-level applications.
