1178 MONOCHROMATORS AND SPECTROGRAPHS BENCHTOP SPECTROMETERS MINISPECTROMETERS SINGLE CHANNEL DETECTION SYSTEMS AND CCD CAMERAS FT-IR SPECTROMETERS Phone: 1-800-222-6440 • Fax: 1-949-253-1680 S p e c t r o s c o p y I n s t r u m e n t s ACCESSORIES FOR SPECTROSCOPY INSTRUMENTS Oriel Mini Monochromator 78024 Mini Monochromator These new Monochromators are low cost, compact and simpleto- use instruments for moderate resolution applications. They are ideal for general laboratory experiments and educational studies covering fixed wavelength ranges and not requiring subnanometer resolutions. The focal length of these instruments is 74 mm; the F/# is 3.9. For demanding spectroscopy applications, please refer to our long focal length, high resolution bench-top instruments detailed on pages 1184 through 1196. Manual and Motorized Versions We offer two families of Mini Monochromators: Manual Monochromators These models have a knurled knob, which causes a precision lead screw/sine bar mechanism to rotate the grating. A digital counter displays the wavelength in nanometers, to 0.2 nm. Motorized Monochromators For scanning applications, we recommend that you choose a motorized monochromator. These instruments use a stepping motor driven by an external motor controller with RS 232 interface. Included with the controller is an application program with over 25 commands to control a variety of operations of the grating drive. These motorized models also include a manual drive and a digital counter that displays the wavelength to 0.2 nm. Fig. 1 Optical configuration of Mini Monochromator • Low cost, very compact instruments for general spectroscopy applications • 74 mm focal length, moderate resolution • Manual and stepping motor driven models • VIS - NIR (190 nm to 1.2 ìm) models • Optional VIS-NIR light source Optical Configuration Fig. 1 shows the Ebert-Fastie design of these monochromators. Full spectrum radiation is focused at the entrance slit and reflected by a folding mirror onto a spherical collimating/focusing mirror. This mirror collimates the radiation and directs it onto the grating, where it is diffracted. Once diffracted, the radiation is directed back to the collimating/focusing mirror, and a segment of the dispersed radiation is focused at the exit slit via a second folding mirror. Resolution The resolution of the instrument is a function of its focal length, the dispersion of the grating, the width of the entrance and exit slits, and to a lesser degree, wavelength. As standard models, these instruments include two 300 ìm x 4 mm slits. You can increase the resolution by using narrower slits. Request different slits at the time of purchase, or purchase extra sets so you can vary the throughput and resolution. The slits are easily interchangeable. Table 1 shows the resolutions possible with the standard and optional slits.
