1. BEFORE USE
1.1 Outline of the Blocker
The NIDEK intelligent blocker, ICE mini, blocks the lens with a lens cup.
In the Blocker/LE and Mini LAB systems, the ICE mini, when connected to a tracer equipped lens
edger, loads shape data and displays the data on the LCD touch screen. In the Blocker LAB, VCA
(Preset), and VCA (Auto) systems, the ICE mini loads JOB data and blocks the lens.
When the lens layout is entered, aligning the lens markings with the scale makes blocking easily.
The ICE mini performs lens blocking by manual operation of the arm.
This blocker has the following features.
• Saves 30 JOB data items and 200 PTN data items in memory. (Blocker/LE and Mini LAB
systems)*1
• Flexible lens support retains the lens securely and blocks it accurately.
• Provides clear display with a 8.4-inch color LCD touch screen.
• Changes lens images into any desired shape with the shape change function.
• Connects two lens edgers directly. (Blocker/LE and Mini LAB systems)
*1. When the saved PTN data exceeds 200 items, the data can be saved also in the USB memory. If interested, contact NIDEK
or your authorized distributor.
