FOCOVISION SPV-3;

The Focovision by Transmission SPV-3 is used in prescription laboratories. It is connected to your computer network, from which it receives the nominal values of the prescription lens. Its main advantages are repeatability, accuracy, easy calibration, and especially its visualization system of the semivisible marks or the upper segment line corner of the addition. This system permits an accurate positioning on the different control points without any lens marking. 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 has a user friendly interface permitting an operator to learn how to perform the complete lens control (far view, prism reference point, near view, thickness, shape, etc.) with little training required. Minimal training required Very high measurement speed Flexibility (configurable procedures, easy to adapt, any toleran
