Imaging Spectrograph, High Res., Fixed Slits, RS232/GPIB, Dual

The MS260i is a high performance, economical and user-friendly imaging spectrograph – an ideal instrument for research and OEM applications. The instrument is fully calibrated and includes diffraction gratings and a built-in shutter. It is designed to be fully compatible with the Oriel^® Filter Wheel model USFW-100 and APEX2 Illuminator, where up to six order-sorting filters may be installed.

The MS260i uses an asymmetrical in-plane Czerny-Turner optical configuration. The optical configuration is designed to ensure high resolution and maximum throughput. This F/3.9 spectrograph has a flat, 28 mm image plane for multichannel detectors. The MS260i is optimized to provide excellent stray light rejection while the toroidal reflectors produce accurate images of the input slit in the flat output plane. Its wavelength drive is designed to increase speed as much as possible without sacrificing accuracy or precision. Stray light is negligible, re-entrant spectra are eliminated, throughput is high, and spatial and spectral resolution are impressive. For dual grating instruments, aberration limited spatial resolution is 40 μm (FWHM).

LabVIEW™ based utility software is included to control both the spectrograph and filter wheel. In addition to the utility software, the MS260i may be controlled using the Oriel TracQ™ Basic software or optional hand controller. An easy-to-understand command set is provided in the user’s manual for those wanting to create their own programs. An optional mounting plate conveniently fastens the spectrograph to an optical table. Threaded holes on the mounting surface also allow rod mounting of the MS260i.
