Czerny-Turner imaging monochromators and spectrographs for UV to NIR spectroscopy with single-point or array detectors.
The Omni-λ series are Czerny-Turner imaging spectrographs and monochromators with focal lengths of 200, 320, 500 and 750 mm. They are supplied pre-aligned and pre-calibrated, and can be configured for a wide range of applications and spectral ranges from UV to NIR. Each unit works with single-point detectors, InGaAs cameras or CCDs and accepts accessories such as filter wheels, fiber adapters, shutters and motorized slits.
Key Features
- Four focal lengths: 200, 320, 500 and 750 mm (f/3.5 to f/9.7)
- Czerny-Turner imaging design, supplied pre-aligned and pre-calibrated
- Interchangeable triple grating turret on Omni-λ300i/500i/750i (dual turret on Omni-λ200i) for quick changes of wavelength range and resolution
- Resolution down to 0.03 nm (Omni-λ750i, 1200 g/mm, PMT)
- Operates as a monochromator or spectrograph with single-point detectors, InGaAs cameras and CCDs
- Accessories include filter wheels, fiber adapters, shutters, motorized slits and sample chambers
- Control software for single-point detector and CCD acquisition; LabVIEW driver for user programming
Typical Applications
- UV–VIS–NIR spectroscopy
- Raman and photoluminescence measurements
- Tunable monochromatic light sources
- Absorption, transmission and reflectance measurements
- Imaging spectroscopy with CCD or InGaAs cameras
