Prescription Version with frame positioning assistance.
The FocovisionTM 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 performs a lens optical power measurement compliant with ISO/ANSI standards by using a light beam according to ‘IOA’ (Infinity On Axis) configuration at a certain wavelength (546 nm or 587nm) and by measuring in all directions (360 degrees - «ring method). In addition, it’s 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.
• The NEW FOCOVISION SPF-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.
Accurate and consistent:The FOCOVISION measures the optical lens power by transmitting a light beam, in all directions (360 degrees) through the lens in accordance with the ANSI, ISO, customized ... standards.
It accurately measures optical power to 0.02D and prism power to 0.02 cm/m, +1%.
Powerful Data analysis- The actual parameters of the measured lens can be transmitted back to the host computer via the FOCOVISION server. This information can be stored as part of the record for the job for reference at a later date.
The data can also be used in a production control analysis to assist the lab management in improving the production process.
The FOCOVISION server can also provide a data download of the records of measured work to a secondary software analysis system if the customer prefers that method of production process control.
