LIONoptics – Innovative optical solutions for professionals

Located in Delft, where Antoni van Leeuwenhoek invented the microscope in 1674, LIONoptics is developing, producing and selling advanced optical instruments.
While Van leeuwenhoek’s invention opened up the world of microbiology, we aim at providing optimal tools for the examination and appraisal of artefacts, to be used by the art professional.

The first microscope, built by Antoni van Leeuwenhoek

Our first product on the market is the InSpector: a high-tech instrument for inspecting and appraising artefacts. It is based on our X-polar technology for observing the true colors of the artifact, and for studying details like signatures with much more contrast and definition.
Look here for a demo.

Besides the X-polar vision, the InSpector also provides a strong and very pure UV beam, for detecting all kinds of materials like varnish, glue, metals and plastics. Finally it contains a high quality jewelers’ loupe for close inspection, with a soft white lighting.
The body is made of aluminium, provided with a hardwood handle.
