Venus camera

The Venus Camera

Wild Insight Ltd

Ely Optics Ltd have designed and implemented a number of underwater optical systems. One of the most demanding was the optics for Wild Insight's "Venus" camera. The requirement here was to provide an image recording and illumination system suitable for dive depths down to 2000m. Features such as illumination spectrum, detector sensitivities, optics survivability and manufacturing cost were all highly relevant. The system is very successful and unique results have been achieved from the pioneering studies.

In a similar vein, Wild Insight has investigated the application of the Venus technologies to a diver camera. Again Ely Optics have designed and assessed the optics for this demanding application.

Integrating Sphere Simulation

Integrating Sphere Simulation

Optical Modelling with Zemax : Photometry

The Zemax optical modelling software can be used for a variety of different applications. Here Ely Optics has modelled the performance of an optical integrating sphere so that the transmission characteristics of an optical system can be assessed before that system enters production. This enables, for example, the influence of different glass choices to be characterised without the need for physically building each and every system.

Light Guide Simulation

Optical Modelling with Zemax : Mechanical Models

Together with the modelling of more conventional optics Zemax can simulate complex optical systems through the import of mechanical CAD structures such as, amongst others, IGES or STL files.  Ely Optics has successfully modelled and assessed parts such as light guides and plastic moulded parts.

Anything really...

Optical Modelling with Zemax : Light Source Simulation

Many simulation applications require the very accurate modelling of a light source.  To achieve this Ely Optics uses the “ProSource” software enabling ray data bases to be established through the photometric (or radiometric) measurement of real light sources.

This very powerful technique enables the integration of a ‘real’ light source with a proposed optical design, thus providing a most realistic evaluation of the system.

Fresnel lense

Fresnel lens
for follow spot applications

Fresnel Lenses

Various lenses have been designed with stage, television and performance in mind. These lenses are Fresnel types, designed specifically for spot lights, or flood lights, and are moulded from heat resistant borosilicate glass.

Smoke detector

Final optical smoke detector

Optical cell

Optical cell for the early detection
of small particulates from fires

Optical Smoke Detection

In order to enable the early detection of fire a detector sensitive to small particulates is required. Such a detector can be realised optically and one was designed and implemented for one of our clients. The cell itself was designed together with test instrumentation (automatic visual inspection) for production units

Down lighter

Down lighter

Various lighting products have been designed from multiple fibre optic configurations through to faceted down lighters. The one illustrated here was designed for a major UK producer.

Display Box Optical Controller

To minimise the number of fluorescent tubes contained in an advertising display box. The aim of the project was to flatten the polar distribution from a fluorescent tube so as to create a flatter distribution with less overlap and hence fewer fluorescent tubes. This will provide advantages such as less heat generation and more pleasing distribution.

The solution was to design an extruded Fresnel like lens spaced a small distance from the fluorescent tube such that more light is directed to the edges of distribution and less to the centre.

Fibre Connector Production Tolerances Investigation

An analysis was conducted of an advanced fibre optic connector using typical manufacturing tolerances. The exercise was able to identify key, or most sensitive, tolerances so that manufacturing effort could be targeted at the most important. As a result of the investigation and subsequent manufacturing effort product yield was improved and a more consistent product supplied.

A somewhat similar exercise was conducted for a deep sea, high temperature and abrasive environment connector with equally successful results.

Industrial Borescope

Ely Optics was approached by a manufacturer of industrial test equipment to design a Borescope capable of operating and surviving with high tip temperatures. This was achieved through a combination of optical, mechanical and thermal engineering. A reliable and robust solution has been demonstrated and has now will be placed into production.
