FOCOVISION SPF-3

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.
