New 20X20 R12.5mm cylindrical lens

Small is beautiful! perhaps, but certainly the small size of the new cylindrical lens makes it usable in multiple applications. The material used is REVO-01, See link REVO-01 The basic dimensions are 20X20mm, edge thickness 3mm, radius of curvature 12.5mm Refractive index (nd) 1,507, dioptric power (Sph) +51, back focal length 18.5mm To see the…

Design & Function

Lenses in a projection system are often studied according to the specific requirements of the application, therefore angular distribution, efficiency, homogeneity of the projected light etc. At other times the lens is an integral part of the device design, therefore it must have a shape approved by the designer and in harmony with the whole…

“rough” projector lenses

When you think of a lens, you generally imagine a solid with two curved surfaces (concave and / or convex) both shiny, i.e. completely transparent. In some lighting applications, a surface of the lens that is “rough”, saying it is not shiny, can be a simple solution to make the projected light more homogeneous and…

Custom light diffusers

IODA is increasingly focused on the creation of “custom” lenses for lighting applications, sharing our knowledge in the world of optics in order to support you in the development of new LED lighting systems. Starting from lenses developed in our laboratories, as in this case in the C Series models (

Battery led module

IODA, in collaboration with LLS Italia and Disway, produces a complete green lighting system (520nm). The system has the possibility of collimating the light providing an angular opening between + / 10 ° and +/- 2 °. The system can work wireless as it is present on the lithium batteries. The Led module provides a…

Array Led Lens on demand

IODA is able to design and build lens modules (also called matrices) to be combined with a PCB already existing, studying the most suitable optics according to the angular distribution of the required light and also considering the mechanical constraints (distance between the LEDs, dimensions, etc.). Thanks to the skills developed in the use of…

Set taratura frontifocometro

Up-grade Focimeter Set

Following the required standards, IODA has obtained compliance with ISO 9342-1: 2005. It is possible now to use in addition to the basic set of 12 lenses, further 4 prismatic lenses of diopters 2, 10, 15, 20. In this way IODA extends the verification range and accuracy of optical device measurement. Link Focimeter calibration set

Spherocylindrical-power reference lens

IODA has made this octagonal lens with one spherical surface and one toroidal surface that is used to check the non-symmetric error given by the automated focimeter after calibration. The specially mounted spherocylindrical-power reference lens with a power of –2,00 D sph/–1,50 D cyl, of ophthalmic form and quality conforming to ISO 8980-1, shall have…

Prisms

IODA has developed in the years experiences and competence to realize special tools for the production of prisms. The materials for the production of prisms are the following: – REVO-01 (Polyurethane) n=1,51 – Mineral (Crown) as BK7, Flint (KzF2) and others. Benefits Ioda can produce prisms with different dimensions and angles, according to customer needs.

Ultra narrow light beam

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…
