Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Using the methods of photoresist reflow and moulding, bifocal and negative microlens arrays, with diameters down to 10 μm, have been fabricated in GaN-on-sapphire. The optical properties of these microlens arrays were characterised by a recently developed reflection/transmission confocal microscopy technique and agree well with calculated values.
