Inspecting microsystem technology components

I-Sys Automation Technology uses a Lynx stereo microscope to inspect critical moulded components used in microbiological test systems.

I-Sys Automation Technology develops and manufactures a range of precision microsystems components used in microbiological test systems.

A Lynx stereo microscope is used to inspect these critical moulded components as well as for quality control of the mould tools used in their manufacture.

Biodisks allow for multiple tests to be carried out on a tiny sample of liquid, reducing the time, equipment and sample volume that would normally be required.

The I-Sys biodisk contains 32 separate test chambers, each of which can carry out a unique reaction.

The test liquid is injected into the central test chamber of the biodisk, where capillary forces then draw it through micro channels into the 32 surrounding analysis chambers.

The biodisk is moulded in a clear plastic, which once used will be studied by an automated inspection station, where each analysis chamber will be studied for colour and contrast changes.

The clear plastic makes inspection of the manufactured component more challenging, as it has been designed to be as clear and contrast free as possible.

The solution chosen by I-Sys Automation Technology is the Lynx stereo microscope from Vision Engineering.

Lynx presents a bright, clear image through the innovative eyepiece-less viewing head.

This image allows the operator to clearly see the features within the clear plastic moulding.

In particular, the micro channels can be inspected to ensure that the sample liquid will flow smoothly through the disk during use.

This Lynx system is operated with a 20x stereo magnification, allowing the operator to clearly see small features on a low contrast component.

The microscope is mounted on a boom fixture which allows for simple manipulation of the components under the optics, as well as a large working area ensuring a comfortable operating posture for the user.

The six-point "shadow-free" fibre-optic ring light provides bright, uniform illumination of the component.

In addition to the biodisk inspections, I-Sys Automation also uses the Lynx for inspection of its tooling and preproduction samples.

In these applications, it is important to use a microscope which allows for fatigue-free inspection.

With the eyepiece-less viewing head and ergonomically optimised boom stand, Lynx allows operators to carry out critical inspections for long periods of time, without the discomfort and drop in efficiency usually associated with long term microscope use.
