Optical Surfaces Ltd, a leading supplier of high precision reference optical flats to leading research establishments and national standards laboratories worldwide, reports on growing demand for larger (350 - 600mm clear aperture) diameters.
As the power of laboratory lasers increases, aspheric lenses and mirrors have been pushed to deliver extremely high intensities. Around the world, nuclear research laser facilities are increasingly using powerful, amplified, ultrashort-duration pulses of coherent light in order to deliver massive energy densities at a given target. Synchronizing the delivery of these high-power pulses creates extreme conditions, in which scientists can carry out state-of-the-art nuclear research. It also allows research into conditions that exist only in distant and exotic environments, for example, th...
New Polishing Technique Improves Finesse of Fabry Perot Etalons Optical Surfaces Ltd. reports on the development of a new polishing technique that has been shown to reproducibly improve the spectral filtering capability (finesse) of Fabry Perot etalons.

12 Mar 2021 Share: Researchers have been asked to use large field-of-view digital holography to accurately apply 3D tracking to mosquito flight. By capturing the diffraction pattern of mosquitoes in a telecentric volume, the insects' flight behaviour will be mathematically recorded, tracked and analysed to speed the development of new vector control products in the fight against malaria.

Off-Axis Parabolic Mirrors Assist Accurate 3D Flight Tracking Mar 3 2021 Optical Surfaces Ltd has been selected by the Optical Engineering Group at the University of Warwick (UK) School of Engineering to supply key focusing optics to enable accurate 3D tracking and analysis of mosquito flight behaviour. The UK Engineering and Physical Sciences Research Council (EPSRC) funded research project at the University of Warwick will utilise large field-of-view digital holography for accurate 3D tracking of mosquito flight in an elongated flight chamber. Using this video-tracking methodology, research...
