Prismatic ophthalmic lens blocker PRA

Layoutblocker-PRA is a manual, high volume ophthalmic lens surface blocker. It features lens blocking with alloy. Ever thought about moving away from alloy blocking? Non-alloy lens production avoids the negative environmental, health impacts and improves quality and efficiency. Traditional alloy lens blocking The Layoutblocker-PRA fits best in traditional production environments where alloy is still be used. In general, labs of this kind are less industrialized. These labs can profit from Layoutblocker-PRA. Basically, the manual ophthalmic blocker is the best solution when high throughput alloy blocking is needed. 2 blocking stations provide precise, fast and easy blocking for highest productivity. Alloy Blocking Technology Furthermore, process data can be entered from a host computer via optional bar code scanner or manually. In addition, control software automatically checks the correct selection of the block-ring. Layoutblocker-PRA features an optical lens recognition system: a “go/no go” indicator alerts the operator when the lens is correctly positioned. Easy to use The system automatically adjusts prism angle, prism base and the axis of the blocking chuck. Finally, the precise auto-fill feature creates a consistent alloy wafer on every lens – minimizing operator intervention.
