Performance of N-series lenses

The efficiency of an optical system of illumination, or performance, is a dimensionless number with a value between 0 and 1, or, when multiplied by 100, is expressed in percentage. The efficiency of an optical system is the ratio of light emitted by the source (incoming light) and the light emitted from the optical system…

Cylindrical lenses

IODA makes a wide range of plano-convex cylindrical lenses. The cylindrical lenses have magnification in only one axis, therefore these lenses can change the height of an image without changing the width of the image. These lenses are also used in the lighting applications, to collimate the LED light and to create lines of light.…

REVO-01 The ultimate Led lenses material.

IODA is a company engaged in the design and production of lenses. Therefore the technology developped for the management of the light beam emitted from a LED source is not based on the study of the reflectors, but of lenses that are penetrated by the light emitted that “drive” the light beam by adjusting the…

1,7RT – Titanium aspheric semi-finished

Since 2013 the new TITANIUM 1,7 RT aspheric semi-finished have been available to create finished lenses from +8,00 to + 15,75 diopters. The design comes from the “Ray Tracing” technology, which has been developped with the collaboration of the University of Padova. “Ray Tracing” allows to calculate the vision ray with a great precision and…
