The main component of the OptiXplorer is a HOLOEYE spatial light modulator (SLM) with SVGA-resolution of 800 x 600 pixels. It is used in various applications such as image projection, adaptive optics, optical metrology and diffractive optics. The kit also contains a detailed tutorial, application software, a 10 mW @ 650 nm laser module with beam expander and focus adjust, SLM mounting ring, laser mount and cable set. It is a powerful product that allows the demonstration and active exploration of a wide range of optical phenomena for students at universities and university-level institutions. The collection of experiments was developed in co-operation with the Institute of Solid State Physics at the University of Bremen, and the Laboratory for Coherence Optics at the Institute of Physics at Humboldt University Berlin. The tutorial covers a wide range of experiments, e.g. amplitude modulation in projection set-ups, polarization properties, LCD characterization, diffractive optics elements, dynamic diffraction, spatial filtering and phase modulation in a Mach-Zehnder interferometer. HOLOEYE Photonics AG is a provider of products and services based on micro-structured optical components and computer-controlled optical wave manipulation. The company's main focus is on the development of adaptive micro-optics and diffractive components for scientific and industrial applications. Products include spatial light modulators and diffractive optical elements. HOLOEYE's spatial light modulator (SLM) systems are based on liquid crystal micro-displays. These devices can modulate light spatially in amplitude and phase, so they act as a dynamic optical element. The optical function or information to be displayed can be taken from the optic design directly and can be transferred by a computer interface. Implementation is straightforward due to the smart system architecture and by easy addressing using VGA or DVI signals directly from a computer graphics card. In many cases there are no additional optical devices necessary or the SLM can be incorporated in existing optical setups and devices. HOLOEYE also manufactures diffractive optic elements. Diffractive optics have unique properties that enable them to realise optical functions that are otherwise difficult or impossible with conventional optics, and can even perform the conventional optical functions of lenses, prisms or aspheres. Their advantages include reduced weight and size, but the main feature of diffractive optics is that they can act like optical wavefront processors. For full details click here.
