OTI Laser Lens Centring Systems
This unique range of equipment fulfils the need of modern lens manufacturing
by measuring and allowing quantified control of centring errors.
All these instruments have a built-in calibration facility thus
ensuring reliability of out-put data.
The technical literature providing authoritative information listing
the essential metrological aspects of lens mounting, potting and
doublet cementing is also available.
fig 1. This shows the typical configuration for potting
of infrared elements. The basic system can be re-configured for
many applications e.g. doublet cementing or setting prior to edging.
fig 2. This measures the DEVIATION of glass elements and
requires no special jigs for component location.
