FOCOVISION SPV-3

The Control Unit for Prescription Lenses is a machine dedicated to prescription labs producing at least 1000 jobs per day. This multi-functional automatic machine is the only one on the market to combine the lens inspection according to the ISO/ANSI standards of all lens types, the mapping of freeform lenses, the flexible digital inking and the laser engraving. The measurement data exported by the machine are very useful for an effective process control. The Control Unit for Rx lenses is the perfect tool to increase your customer satisfaction, by improving your quality and optimizing the delivery times.

The Dual LensMapper, integrated in this unit, gives a mapping of the prescription lens (freeform or conventional) and calculates FOA optical power at the reference points (FV, NV). For the freeforms, it compares the expected design to the real lens and displays an error map. A Go/NoGo decision is made, based on the error map and the list of criteria defined by the lab. Because the A&R AutoMapper is task specific, and the system has a small footprint, you can easily integrate it into the lab, either directly after the surfacing or in the final control (also suitable for checking the cut lenses). The AutoMapper is an excellent investment for a modern lab with a rapid payback! 100 % production control just after surfacing --> direct feedback on production* control of the cut lens - in case of remote edging Non contact measurement Correction of eventual R/L inversion Integrated Dual LensMapper : measurement of free form and conventional progressive lenses Control of power, cyl.

The ProMapper is the A&R table-top solution to provide state-of-the-art optical inspection according to the industry standards (ISO/ANSI), totally independent from the operator. In addition, it supplies freeform surface evaluation based on the A&R Error Map technology, making sure that no surface defect is shipped to the customer. Based on the Error Map, surface quality features like the GMC (Global Mapping Criteria) are evaluated and constitute extremely relevant inspection data for process control applications (Statistical Process Control).

The Focovision by Transmission SPF-3 is used in optical laboratories where the lenses are mounted into frames. It is connected to the computer network, from which it receives the nominal values of the prescription lens. Its main advantages are repeatability, accuracy, and easy calibration. It measures the lens optical power by using a light beam perpendicular to the concave lens surface at a certain wavelength (546 nm or 587 nm) and by measuring in all directions (360 degrees). In addition, it is equipped with a frame positioning device and has a user friendly interface; permitting an operator to learn how to perform the complete lens control of the mounted lenses with little training required. Positioning assistance: The FOCOVISION display provides assistance to the operator to help them position the frame and lens to be measured properly, creating a user friendly and fast process.
