Coburn Introduces Spectrum Prismatic Lens Blocker

Coburn Technologies recently announced a new innovation in Lens Blocking Systems, the Spectrum Prismatic Lens Blocker

Designed for compatibility with all common surfacing machines, the Spectrum Prismatic Lens Blocker provides extremely precise alignment of the lens at the correct prism angle.

“The distinguishing feature of sagging the front curve during the alignment process to ensure a more accurate lens also assures that a proper blank is blocked. The Spectrum Prismatic Lens Blocker operates within a small footprint, is user-friendly and has an autofill function,” states Alex Incera, President of Coburn Technologies.

It also provides all this functionality at a price point not
previously seen in the marketplace. The Spectrum Blocker measures the front curve of the lens and warns the operator if the blank is incorrect, virtually eliminating blank selection errors. This measurement can also be provided to the LMS for modification of back curve calculations to produce a more accurate lens.

The Spectrum Blocker is available with multiple blocking ring configurations from 50 mm to 63 mm and is also available in a plano (non-prismatic) version. The Spectrum Blocker will be on display at this year’s Vision Expo West 2019 in Las Vegas.
