CUBES, the Cassegrain U-Band Efficient Spectrograph (2022)
Presentation / Conference Contribution

In the era of Extremely Large Telescopes, the current generation of 8-10m facilities are likely to remain competitive at ground-UV wavelengths for the foreseeable future. The Cassegrain U-Band Efficient Spectrograph (CUBES) has been designed to provi... Read More about CUBES, the Cassegrain U-Band Efficient Spectrograph.

Adaptive optical methods for in vivo imaging in developing Zebra fish (2012)
Presentation / Conference Contribution

The humble Zebra fish is rapidly establishing itself as the model of choice for a wide range of biological investigations, in particular at the developing embryo stage. Single Plane Illumination Microscopy (SPIM) has already been shown to be a very p... Read More about Adaptive optical methods for in vivo imaging in developing Zebra fish.

Heart synchronization for SPIM microscopy of living zebra fish (2011)
Presentation / Conference Contribution

We describe work on producing a selective plane illumination microscope for cardiac imaging in zebra fish embryos. The system has a novel synchronization system for imaging oscillating structures (e.g. the heart) and will have adaptive optics for ima...

An optical platform for the production, trapping, manipulation and visualization of ultra-low interfacial tension emulsion droplets (2013)
Presentation / Conference Contribution

We discuss the design, implementation and performance of a novel platform for the production and optical control of ultra-low interfacial tension droplets in the 1-10 micron regime. A custom-designed, integrated microfluidic system allows the product...

Creating correct aberrations: why blur isn’t always bad in the eye (2020)
Presentation / Conference Contribution

In optics in general, a sharp aberration-free image is normally the desired goal, and the whole field of adaptive optics has developed with the aim of producing blur-free images. Likewise, in ophthalmic optics we normally aim for a sharp image on the... Read More about Creating correct aberrations: why blur isn’t always bad in the eye.

Opto-mechanical designs for the HARMONI adaptive optics systems (2018)
Presentation / Conference Contribution

HARMONI is a visible and near-infrared integral field spectrograph equipped with two complementary adaptive optics systems, fully integrated within the instrument. A Single Conjugate AO (SCAO) system offers high performance for a limited sky coverage... Read More about Opto-mechanical designs for the HARMONI adaptive optics systems.

The reformatting advantage: photonics vs conventional optics! (2018)
Presentation / Conference Contribution

In recent decades, spectroscopic capabilities have been significantly enhanced by new technological developments, in particular spatial reformatting. Spatial reformatting allows multiple functionalities: the observation of a larger area of sky, obtai... Read More about The reformatting advantage: photonics vs conventional optics!.

Auto-tuned thermal control on stratospheric balloon experiments (2018)
Presentation / Conference Contribution

Balloon-borne experiments present unique thermal design challenges, which are a combination of those present for both space and ground experiments. Radiation and conduction are the predominant heat transfer mechanisms with convection effects being mi... Read More about Auto-tuned thermal control on stratospheric balloon experiments.
