FOCOVISION SPF-2

The Focovision by Transmission SPF-2 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.

BENEFITS

• 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. The positioning target, displayed at every step of the procedure, and operator instructions projected on the monitor are easy to see and understand.

• Each lens position, within the frame (correct mounting) is checked in accordance with the micro-engravings of the progressive or the segment for bifocal lens which reduces subjective interpretation of the measurements and verifies proper lens mounting.

• For single vision jobs, automatic recalculation of measured results (prism, decentration) is possible without tedious positioning by the operator (the operator doesn’t need to position at the optical center anymore). Horizontal and vertical imbalance is determined by the software within the FOCOVISION.

• A diagram on the screen displays the difference between the measured values and the target values of the lens parameters for easy and precise understanding by the operator.

• A barcode reader, to easily interface the FOCOVISION with the host computer, is included.
