Chemical etching from Tecan helps meet the challenges facing the optical industry where there is an ongoing demand for small sizes, excellent corrosion resistance, precision tolerances, mechanical strength properties, as well as material biocompatibility. It helps to deliver short lead times, burr-free components and precision at a micro-scale.

Using it, we achieve an extremely high level of accuracy, creating fine apertures with no burrs. From prototype to high volume and working with measurements from 5 microns to 1mm, we provide bespoke-designed components with finishes appropriate for use with optical applications such as reflection-reducing blackening.

Typical products we produce include:

  • optical encoders
  • actuators
  • embossing tools for lens arrays
  • graticules and reticules
  • deposition masks (shadow masks /stencils)
