FOCOVISIONTM SPV-3:
Prescription Version with visualization of the technical marks.
The FocovisionTM 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 performs a lens optical power measurement compliant with ISO/ANSI standards by using a light beam perpendicular to the concave lens surface (‘FOA’ - Focus On Axis configuration) at a certain wavelength (546 nm or 587 nm) and by measuring in all directions (360 degrees - "ring" method). 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.
Latest development :
• The NEW FOCOVISION SPV-3 software is based on Windows 10 Embedded OS.
• A new light source provides an improved ring image. Effect of local defects (dusts,...) are detected and corrected using a proprietary technology. The new light source, based on the long-life LED technology can easily be exchanged (plug and play), leading to better accuracy in lab conditions.
