| • Characterize light sources and materials over all or part of the entire UV/VIS/IR region (200 nm to 30 ^m) • Measure true RMS intensities of AC, pulsed or modulated sources • Measure total, peak, average, apparent intensities and time profiles of pulsed and navigation lights • Eliminate noise from sources and detectors • Attain the ultimate in sensitivity, down to and including counting individual photons • Computer control for integration into existing measurement procedures or custom data analysis The OL 730D is an extremely versatile radiometer utilizing state-of-the-art digital signal processing (DSP) technology. When used with a wide range of optional photodetectors and input optics, a multitude of high accuracy radiometric and photometric measurements can be made over all or part of the entire ultraviolet, visible and infrared spectrum. The OL 730D features several modes of operation. It can be operated as: • a high sensitivity DC amplifier, typically used in photometric or radiometric measurements in the UV/VIS/NIR regions • an AC lock-in amplifier, typically used for measurements in the IR (1.8 to 30 pm) and highly modulated source applications • a photon counterforextremely low-light-level measurements. Ultra high-speed data acquisition is another important feature of DSP technology. This means that the OL 730D can measure the output of pulsed or rapidly changing sources in addition to performing source profiling. The OL 730D is a completely microprocessor controlled, multi-functional radiometer/photometer, which can be programmed to read directly in any user specified radiometric or photometric optical quantity. The OL 730D is virtually ideal for all types of measurement and features high sensitivity, autoranging, auto-zeroing, highly accurate readout and range-to-range linearity, 4% digit (6% digit via computer) plus exponent display, user variable response time, an extremely large dynamic range and RS-232-Interface (IEEE-488 optional) for computer control. Multiple calibration factors for different detector/filter/input optic configurations can be stored in memory. Once the desired configuration and associated calibration factor is selected, the OL 730D will measure and read directly in the designated optical units. Bulletin 134/Rev. 6-06 |
