Optical Surfaces is an international manufacturer of Off-Axis Parabolic Mirrors (OAPs) for demanding imaging applications. Off-axis parabolic mirrors can be a useful tool in optical design. OAPs combine the achromatic and diffraction limited imaging properties of a parabolic mirror with the ability to deviate the light path off-axis, which is useful for most imaging systems.
Heat is a byproduct of operating any sized electrical circuit. Most problems in electrical systems display themselves in terms of heat. Electricians must be able to classify a circuit as normal when the load is on or identify when it is abnormal and identify the issues that presents – finding hot spots that need attention.

Benefiting from a facility where temperatures remain constant year-round and vibration is practically non-existent, Optical Surfaces has been able to routinely produce and test demanding telescope spectrograph optics (aspheres, flats, lenses, mirrors and prisms) that aims to stretch the limits of conventional optical fabrication techniques.
The optimal beamsplitter can take on many forms including cubes, plates, hexagons, pentagons, polarising, non-polarising or wedge designs in a wide variety of reflection / transmission ratios and substrates depending upon your application.
Optical Surfaces is manufacturer of large, high quality prisms for spectroscopic, surveying and telescope applications. Prisms are solid optics that are ground and polished into geometrical and optically significant shapes where the angle, position, and number of surfaces help define the type and function. Spectroscopic applications typically demand that prisms must be manufactured with very strict tolerances and accuracies.
With the increasing use of antimicrobial drugs, the evolution of pathogens and diseases has increased exponentially. The need to better characterise and elucidate novel pathways to neutralise or eradicate these threats is of paramount importance.
Signify has been chosen as the main provider of underwater LED lighting for the marine-based fish farms of Australis Seafoods in Chile. Australis chose Signify because of its commitment to a sustainable world, strongly supporting Australis’ objectives for responsible and efficient fish farming.
Resolve Optics has announced its active participation in designing and supplying robust optical systems for a range of different space projects over the last few years. Designing optical systems for satellites and spacecraft is challenging due to the harsh conditions that space places upon components and systems working in this remote environment.
Katai announced today the availability of its next generation, high resolution 360° video camera named BlueJay. BlueJay features a number of industry firsts such as: a 48 Mega Pixel advanced sensor, a very wide and automatically adjustable field of view (up to 360°) with a single point of focus, built-in edge analytics and processing.
Avalanche photodiodes (APDs) are very sensitive semiconductors that exploit the photoelectric effect to convert light to electricity and are the semiconductor analogue of photomultipliers. Their spectral response depends upon the substrate used, for example, silicon detects in the ~150-1100nm region, whilst InGaAs extends to 1.7um.
