Example 1: A lens manufacturer wanted a quick and accurate check of the radius of curvature and sphericity of optical components to better than 1 part in 10000

The Solution: A manual instrument was designed based on a video camera and high resolution encoder.
The design includes features that allow relatively low cost components to be used without affecting accuracy.
In a later development the video output was coupled to a PC and software was written to create a fully automated instrument which could be mounted on line.

Example 2: An automotive component manufacturer wanted to measure the residual transmission of a near-opaque coating to better than 1 part in 1000. Instrumentation did exist but was bulky, expensive and designed primarily for laboratory use.

The Solution: A hand-held device was designed using solid state components that could withstand an industrial environment. By tailoring the design to a very specific requirement it was possible to keep it very simple.
