LensColour Analyser TFM-1

The LensColour Analyser TFM-1 replaces the human eye as a visual inspection device for ophthalmic lenses in everyday use. The TFM-1 was specifically designed in cooperation with Rodenstock, Germany, as a fast measurement tool for the use in production and development. The TFM-1 instrument allows the fast and accurate determination of the color values [e.g. L*a*b*], the UV transmissions TUV 380 nm and TUV 400 nm, the light transmission TV as well as additional parameters in accordance with the DIN EN ISO 8980-3 standard of ophthalmic lenses with refractive power of up to ± 20 diopters.
