Manual inspection equipment

Photovoltaic/silicon chip or wafer quality inspection equipment

Near-infrared photoelasticity equipment

This equipment can be used to detect flaws and stresses in silicon chips, wafers and photovoltaic cells. It uses a near-IR light source and detector coupled with GFP technology to measure stresses within the silicon. It can be used to determine machining stresses or internal defects which could lead to premature failure.

Low-cost inspection and analysis equipment

Low-cost fibre optic boroscope

This boroscope comes in two lengths and with a variety of accessories. It can be used to inspect difficult-to-access areas for a wide range of applications. Its aligned fibre optics make for a very clear and easily focussed image, which can also be linked to a digital camera.

Pressure distributions measurement

VisEng can supply a range of pressure film to measure contact pressure distribution between surfaces. We can also supply a simple programme to enhance the images and give more details. This is excellent for looking at gasket faces or roller pressure, for example.

Flow visualisation equipment

VisEng has assisted in the development of flow visualisation techniques using rapid prototype models and low-cost laser illuminators and cameras.

We can provide, at a much reduced cost compared to sophisticated PIV systems, a very good flow visualisation package that will allow comparative measurement of velocity flows. The kit comes complete with laser diode illumination and a simple webcam-type camera to give the user unparalleled views of their fluid flow regime. This works with liquids and gases.
