      Lens Surface Blockers

      The latest prismatic lens surface blocking machinery for ophthalmic lenses.

      Coburn offers three new lens blockers – Spectrum, Spectrum?? and Spectrum??. The base model, Spectrum, performs eco-friendly wax lens blocking. For labs that prefer to use alloy, the Spectrum?? and Spectrum?? can be used. Spectrum?? is our most precise prismatic lens blocker, which automatically adjusts the prism axis, magnitude, and the axis of the blocking chuck.

      Spectrum Prismatic Lens Blocker

      The new Spectrum Prism 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.
