S p e c t r o s c o p y I n s t r u m e n t s 1191 Email: sales@newport.com • Web: newport.com MONOCHROMATORS AND SPECTROGRAPHS SINGLE CHANNEL DETECTION SYSTEMS MINISPECTROMETERS BENCHTOP SPECTROMETERS AND CCD CAMERAS FT-IR SPECTROMETERS ACCESSORIES FOR SPECTROSCOPY INSTRUMENTS Our Oriel Cornerstone 260 1/4 m Monochromators are economical, fully automated, multi-grating instruments with dual output ports and exceptional optical performance. We offer a dual grating and a triple grating model; both were designed for fast, automated, continuous scanning over a broad spectral range. Simply program your filter, grating, and port changeover points, and walk away while Cornerstone 260 automatically scans from the UV through the far IR. Other standard features include a built-in electronic shutter, filter wheel control, USB 2.0 or RS-232 and IEEE-488 communications, nitrogen purge for work below 180 nm, and a family of interchangeable gratings and slits. Why The Cornerstone 260? Superior performance and ease of use at an economical price make the Cornerstone 260 Monochromator one of the best choices for UV-IR spectroscopy and radiometry. The dual grating instruments offer improved resolution, over the triple grating instruments. The grating mounts are interchangeable, so if you currently have a triple grating Cornerstone, you can easily convert it to a dual grating instrument for improved resolution in your spectral range of interest. Optical Configuration Fig. 1 Optical design of the triple grating Cornerstone 260 1/4 m Monochromator • New, USB2.0 models • Operate two or three gratings simultaneously, individually replaceable • Dual output ports • Superior resolution and very low stray light Fig. 1 shows the asymmetrical in-plane Czerny-Turner optical configuration of the Cornerstone 260. The input F/number is F/3.9. The resolution is 0.10 nm (dual grating instruments with a 1200 l/mm grating and 10 ìm x 2 mm slit). Throughput is high and stray light is very low. We relied on our extensive research on optical flat black paints and baffles, and the use of high efficiency spherical mirrors and gratings to minimize surface reflections, and thus, stray light. Two Output Ports Cornerstone 260 has two output ports to allow continuous scanning over a broad wavelength range without breaking down the instrument to switch detectors. This switcher is commanded through the Cornerstone 260 software or hand controller. Note that with the help of model 77713 Motorized Beam Steerer (see page 1316), it is also possible to turn the monochromator into a dual input instrument. Instrument Control We offer Cornerstone 260 Monochromators with USB 2.0 or with RS232 and IEEE-488 interfaces. You can communicate with any of the Cornerstone 260 instruments in one of 3 manners. Hand Controller The 74009 Hand Controller is a dedicated interface just for the Cornerstone Monochromator Family. There is no need to memorize commands or key sequences; the 24 keys are clearly labeled with functions like “Step Up,” “Go Wave,” and “Shutter”. The backlit LCD display provides constant information on grating lines/mm, filter wheel position, current wavelength, and shutter status. The 74009 provides intuitive access to nearly all the functionality of the Cornerstone 260. Computer Control The computer interface was also designed for simplicity and ease of use. The Cornerstone ASCII command set is simple to use via RS 232 or GPIB. For example, close the shutter is “SHUTTER C” and change to the second grating is “GRAT 2”.
