Imaging Scanning Monochromator
HORIBA Scientific OEM has developed a high-throughput imaging scanning monochromator based on an aberration-corrected concave holographic grating with low stray light and high efficiency. This proprietary layout with single optics design is ideal for imaging for low-light applications. It features a 3-position external filter wheel, TTL drive electronics, 4-phase stepper motor and associated worm/gear 90:1 ratio mechanism, encoded, aligned and focused at factory.
This instrument can be used as both a tunable excitation light source and a fluorescence emission scanning monochromator, thanks to high grating efficiency in both first and second orders of diffraction. It is also equipped with two opto-sensors and associated hardware for home calibration.
