Omni-λ series grating spectrographs/Monochromator
◆Manual micrometer adjustable slits for precision control of incoming light. Motorized Slit and fixed slit is optional. • More than 100 gratings for the best spectral range, throughput and dispersion to meet your application
◆DSP controlled stepping motor scanning system provides superior precision and repeatability of wavelength positioning
◆Optional internal shutter or six-position filter wheel for experiments requiring background removal or signal attenuation
◆Installation and set-up through USB 2.0 computer interfaces • Stand-alone Omni Series monochromator control software for basic scanning and calibration. Also includes utilities for grating updates and communications
◆ Active X control support Visual Basic, C++ and Delphi drivers allow users to design their own acquisition programs
◆ZolixScan data acquisition software provides a simple user interface for easy data acquisition and experimental set-up
