Built on a Czerny-Turner optical design, the Shamrock 500i imaging spectrometer is optimised for multi-track spectroscopy. It is supplied pre-aligned and pre-calibrated as a camera and spectrometer detection solution so it drops into an existing set-up, with a spectroscopy-dedicated software interface giving real time control of detectors and spectrometer together. Optimised toroidal optics correct image astigmatism for high density multi-track work, and the motorised indexed triple grating turret can be upgraded in the field.

The Shamrock 750 offers the highest resolution in the Shamrock family and also handles multi-track work well. Its rugged Czerny-Turner platform is supported by a wide range of light coupling accessories and gratings, and pairs with Andor's CCD, electron multiplying CCD, InGaAs and intensified CCD cameras. Systems are supplied pre-aligned and factory calibrated, and Solis spectroscopy software provides a single interface for spectrograph, detector and motorised accessory control. A multi-track enhanced option optimises the system for low crosstalk, high density multi-leg fibre signal acquisition.
The Kymera 328i is a highly modular third-metre spectrograph with patented Adaptive Focus, a quadruple on-axis grating turret and TruRes technology for enhanced spectral resolution. Its motorised Adaptive Focus automatically reaches the best optical performance for any grating, camera or wavelength range, while TruRes delivers resolution gains exceeding 30% without changing grating or applying mathematical post-processing. The 328 mm focal length and F/4.1 aperture cover luminescence and photoluminescence spectroscopy through to higher resolution Raman and plasma studies. A robust on-axis wavelength drive gives single-grating and grating-to-grating centre wavelength repeatability down to 4 and 10 pm respectively.
The Mechelle ME5000 echelle spectrograph records a wide wavelength range from 200 to 975 nm simultaneously in a single acquisition. It has no moving components and is available in a pre-aligned detector and spectrometer format, with a patented optical design based on the echelle grating principle that gives extremely low crosstalk and high resolution. Automatic temperature correction compensates for the change in prism refractive index with temperature, and nitrogen purging maximises throughput in the ultraviolet. Andor Solis software extracts a fully wavelength calibrated spectrum from the complex echelle image and can label peaks against the NIST table.
