Spectrum Prismatic Lens Blocker
The surfacing lens blocker just got better. Coburn’s Spectrum Prismatic Lens Blocker is the newest innovation in precise, convenient lens blocking technology. With a smaller footprint than ever before, and a thoughtful design, Spectrum automatically adjusts prism axis and magnitude, and the axis of the blocking chuck.
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. Spectrum 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. Spectrum is available with multiple blocking ring configurations ranging from 50 mm to 63 mm.
