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.
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.
