Spectrum Prismatic Lens Blocker

Spectrum Prism Lens Blocker

The new Spectrum Prismatic Lens Blocker technology automatically attaches the lens block at the correct prism angle, prism base and axis. Compatible with all common surfacing machines, the Spectrum Blocker precisely transports the lens to the chill ring, preventing the opportunity for lens marring or positioning errors. The Spectrum Blocker also measures the front curve of the lens and warns the operator if the blank is incorrect, virtually eliminating blank selection errors. This measurement can be provided to the LMS for modification of back curve calculations to produce a more accurate lens.

Available with multiple blocking ring configurations from 50 mm to 63mm.

Available in a plano (non-prismatic) version.
