A tour around our laboratories

.
Microcavity spectroscopy system, used to measure the reflectivity and photoluminescence emission of organic-semiconductor micocavities and other photonic structures as a function of angle and also temperature (room-temperature to liquid nitrogen).

Thin-film deposition of new materials is typically investigated first by use of a spin coater before scale-up.

Ultrasonic spray coating is used as a manufacturable deposition technique.
Spray-casting is a scalable technique. Less wasteful than spin-casting. Already routinely used in manufacture (e.g. automotive, graphic arts etc)
