OptiChrome™ technology combines several important things
Surgical Microscopes
A method of the Design-Process
A heritage of the latest lens design algorithm and the old traditional of Leica (formally WILD) which goes back over many product- and lens designer generations
A matter of the glass used in the OptiChrome™ design.
It is the abnormal behavior of certain optical materials, used in specific places in the optical system which makes an outstanding design.
Coating is key
In the OptiChrome™ design the latest development in coating design has been applied, that means the reflectance on each surface (change of the optical medium glass-air) has been optimised to the bare minimum. The coating has been matched to the type of glass, you can prove it in the sharp crisp image.
And further to this OptiChrome technology includes also workmanship
Decades of knowledge and experience to work with this exotic materials.
