Lein has developed its patented technology specifically to reduce the size and cost of confocal metrology systems . This has been achieved by combining the source, detector and pinhole assembly into a single compact device. This simplifies the design while still maintaining the resolution that is achieved with traditional confocal systems. Our technology can measure;
Position (sub-micron precision)
Thickness (sub-micron precision)
Concentration and distribution of pharmaceutical drugs (better than 1 μM/L)
Glucose non-invasively via the eye
Underpinning our core confocal technology Lein has developed drive & high speed electronics, optics and state of the art software. As with the confocal technology the focus is to reduce both the size and cost but still provide the same performance that is found on traditional systems.
To overcome some of the obstacles faced by optical instrumentation Lein has developed a number of image processing solutions to support both measurement of and alignment to an object under test. Our image processing technology is efficient and capable of tracking and achieving highly accurate and precise results with respect to measurements of circles and ellipses. Distance accuracies to within 2 µm of calibrated standards, with a precision of ± 1 µm, have been demonstrated.
Fully customisable confocal optical assemblies depending on the application.
Lein’s motion controlled confocal scanning stage is both compact and low cost.
Lein uses sophisticated signal processing techniques to support its technical development. Noise sources and their characteristic frequencies are identified, leading to improved signal to noise performance while analysis of the confocal point spread function offers improved accuracy and precision.
