We took our 30+ years of designing and manufacturing spectroscopic instruments, combined with the feedback from you, our customers, and designed a family of instruments that truly addresses the needs of both the Researcher, and the Systems Integrator. We offer models to cover various spectral ranges, in both fiber-coupled and free-space configurations, for high resolution and moderate resolution needs. Superior UV Performance One of our design criteria was to ensure superior UV performance. After exhaustive testing of numerous arrays, we chose a Si NMOS photodiode array, which has a broad spectral response, excellent sensitivity in the ultraviolet range, and lower cross talk than most other arrays. Because these PDAs have inherently good UV performance, they do not require a UV enhancement coating, which is often used on CCDs, and is prone to degradation over time. The result is a minispectrometer that outperforms traditional CCD-based instruments, particularly in the UV (see Fig. 1), and whose performance does not degrade over time. 3 2.5 2 1.5 200 220 240 260 280 300 320 340 WAVELENGTH (nm) ABSORBANCE UNITS 1 0.5 0 ORIEL IS-SERIES MINISPECTROMETER CCD-BASED MINISPECTROMETER Fig. 1 Caffeine absorbance, measured with IS Minispectrometer and with traditional CCD-based Minispectrometer Low Stray Light The 195 to 250 nm wavelength range is a critical spectral region for DUV spectroscopy. Since the measured signal is often quite low in this range, a low stray light instrument is necessary to ensure accurate measurements. Fiber-coupled spectrometers often suffer from an optical mismatch between the fiber optic’s numerical aperture and the spectrometer’s aperture. This results in sensitivity loss. The Oriel IS-Series are F/# matched to ensure high dynamic range and sensitivity. The F/# of the high resolution instruments is F/3.7; the moderate resolution models are F/2.6 instruments. A combination of internal apertures, well matched optics, and wall finish, lowers stray light. Options for Order Sorting Filters Our high resolution IS Minispectrometers have an integrated filter slide, which holds 1.0 inch (25.4 mm) diameter order sorting filters. The filter slide is on the inside of the instrument's housing; filter insertion and removal is quick and easy. For the moderate resolution 190 - 800 nm instrument, we apply a proprietary order sorting film directly onto the photodiode detector. The standard 400 - 1000 nm version does not come with an order sorting filter but it is available as an order option. Please contact a Newport sales engineer for more details. Fiber-Coupled and Free-Space Models Most minispectrometers on the market are fiber-based instruments. We recognize the advantage of using fibers to deliver the light, but we also recognize their limitations. Direct access to the slit lets you easily and inexpensively change resolution and throughput. It also offers greater flexibility in launching light into the spectrometer, which is important for many Systems Integrators. • NMOS Photodiode detector for superior UV sensitivity • Various spectral ranges from 190 to 1000 nm • High resolution models: 0.45 nm • USB 2.0 communication to PC • Convenient fiber based systems and versatile free-space systems Oriel IS Series Minispectrometers

Our fiber based instruments have an SMA connector; you must order the fiber separately. The free space instruments have a 1.5 Inch Series males flange input; they accept any 1.5 Inch Series female flanged accessory. Fiber Coupled Minispectrometers The fiber-based minispectrometers have an SMA connector, which accepts any properly terminated fiber. We offer standard fused silica fibers and solarization resistant fibers. If you are working below 260 nm, we recommend using a solarization resistant fiber (decribed on page 249) to ensure continued UV transmittance. A fiber is not included with...
