The flat convex lenses (PCX) have a first convex (positive) surface and a second flat surface that give a positive focal length to each lens. The focal length of PCX lenses is in relation with the material used, the radius of curvature and the wavelength of the light radiation taken as a reference. Thanks to…

We design and manufacture lenses for special lighting applications: the lens model ASP-D-83 is a clear example of our job. ASP-D-83 is a plano -aspherical lens used in a light projector; with a single lens we can vary the angular aperture of the light emitted by up to +/- 15 degrees. Benefits Usually a lens…

A solarimeter is a pyranometer, a type of measuring device used to measure combined direct and diffuse solar radiation. Ioda produces the dome of the solarimeter, which has been called Glass Dome. The material used is quartz K5; the dome is optically processed for maximum surface and dimensional quality. Benefits Ioda can also create specific…

The basis of these lenses has two or three holes with interaxis 35mm, but it can be customized according to the specific application. Benefits The aspherical curvature of the lens makes the light emitted homogeneous accross the illuminated area. The illumination system allows higher efficiency, especially for narrow emission angles. Considerable space saving is given…

The lenses of the D series, (abbreviation of Driver), were initially developed for the realization of projectors destined for the automotive after-market market (cars and motorcycles). Thanks to the accurate aspheric profile of the convex lens, developed in collaboration with INAF – Astronomical Observatory of Padovae, and to the use of a new polyurethane material,…

The peculiarity of this lens lies in the edge, since a groove has been created to accommodate an o-ring, in order to guarantee the degree of protection required for outdoor lamps, in this application IP68. (International Protection class). The groove is made directly on the mold, without any additional processing after polymerization; the structure of…

IODA has developed a system that allows to project the profile of an object for the examination, the projected object is enlarged 5 times (5X magnification). The instrument is inserted in a production line, therefore the dimensions and the position of the components are constraints imposed by the customer. The profile projection system consists of:…

Glass Dome SOLARIMETER – PYRANOMETER The dome meniscus lenses are special hemispherical optical elements, often used to protect other elements or systems within which they are integrated; normally found in pyranometers. A solarimeter is a pyranometer, a type of measuring device used to measure combined direct and diffuse solar radiation. Ioda produces the dome of…

The focimeter is a necessary tool for any optician. It responds to the need to have stable reference samples that allow each optician to offer, on the one hand, optically excellent lenses and, on the other, to demonstrate the precision and reliability of the instrumentation in the event of disputes and complaints. The legislation currently…

Aspheric semi finished lenses “High technology” – available in wide range – Among the organic resin lenses, the lenses of aspherical geometry have gradually gained space in the market at the expense of the lenses of spherical geometry. This has happened, because of their lower weight, reduced thickness and high optical quality, which permits the…
