SPECTROSCOPY
Ocean HDX spectrometer The latest spectrometer from Ocean Optics uses a novel optical bench design and high- performance components to provide high throughput, low stray light and excellent thermal stability for integrated, industrial and research applications. The Ocean HDX has a back-thinned CCD array and new high definition optics to deliver a high level of spectral performance for a compact, UV-visible spectrometer. The Ocean HDX has a ‘high- definition optics’ design, which uses a combination of optimised optical bench components, specialised materials and precision engineering to maximise optical resolution, increase throughput, reduce stray light and maintain thermal stability. Applications include:
determination of analytes in solutions – low stray light contributes to high dynamic range and high absorbance linearity (nearly 3AU); low light applications including fluorescence, thanks to use of a back-thinned CCD detector; optical resolution of <1nm (FWHM) and
TeraFlash terahertz imaging extension
At Photonics West, Toptica launched a terahertz imaging extension for its successful time- domain spectroscopy platform, TeraFlash. Owing to the unique spectral bandwidth of the TeraFlash (0.105THz), researchers can exploit the full potential that the combination of imaging and spectroscopic methods has to offer. The imaging
extension uses two precise linear stages to scan a sample through the focus of the terahertz beam. The translational movement is synchronised with the delay-stage within the TeraFlash, speeding up the measurements, allowing the system to acquire complete waveforms for up to 16 pixels
excellent peak symmetry for applications such as absolute colour accuracy. The spectrometer is responsive
from 200 to 1,100nm, with thermal stability of +/-0.5 pixels from 0 to 45°C. Its high thermal stability and small footprint – just 88.9 x 63.5 x 52.4mm – makes it ideal for OEM product integration and industrial applications. Ocean HDX uses X-platform
electronics to enhance its processing and communications capabilities. On-board memory storage and processing functions speed up analysis time. Users can store up to 50,000 spectra and use on-board averaging to capture more spectral data in less time.

per second. The positioning accuracy is better than 200µm over a 15 x 15cm field of view. Co-developed with experts from Fraunhofer Heinrich Hertz Institute (Berlin, Germany), the imaging extension comes in two versions – a ‘basic’ setup for researchers who wish to use their own optical components, and a ‘complete’ version that includes parabolic mirrors for beam shaping and focusing. The ‘complete’ imaging extension offers flexibility – with the help of alignment pins, users can reconfigure the optics quickly from a transmission set-up to a reflection geometry and vice versa.
Both versions feature a
software package that offers a choice of contrast parameters including amplitude, phase and layer thickness.
