The economic changes of the beginning of this century have imposed to modify the DIVEL ITALIA production and its commercial strategies trying to adapt them to new market requirements. DIVEL ITALIA has invested in new technologies equipping itself with new gene ration machineries and original software to offer customers a new range of sophisticated products, designed on the basis of the new requirements and the new lifestyle of the twenty-fifirst century, looking at the same time at safe guarding the quality and glamour of the Italian products. For this reason DIVEL ITALIA has focused not only on technical excellence and aesthetics of the lens but also on the service, creating a network of branches and associated companies able to assist customers in all phases of its work: from sale to assembly lens on frame and after-sales care.
The innovative Blue Natural lenses act as a protective filter for the eye, and absorb these potentially harmful light radiations. They protect the eye completely, blocking UV rays and high-energy blue light up to 420 nm, while allowing for normal colour perception. The latest generation BLUE NATURAL lens is a protective filter able to absorb all the light radiations potentially harmful to the human eye. Part of the light of the "first visible", in particular the blue light (400-540 nm), presents characteristics of high energies that can be harmful to the eye such as UV rays. The BLUE NATURAL lens completely shields against light radiation up to 420 nm, blocking UV rays and the part of high-energy blue light, allowing the part of blue light to pass through the normal color perception. The BLUE NATURAL lens is suitable for those who want the highest visual protection in any environment. The harmful effects of blue light: Red and irritated eyes Ocular dryness Blurred vision Feeling of light annoyance Emergence of eye diseases such as keratitis, etc

The damage caused by UV-A rays is cumulative and permanent, and can affect the cornea, the crystalline lens, the iris, the retina and the related conjunctival and epithelial tissues. The NOuv technology lens completely eliminates UV rays up to 400 nm. The potential harmful effects of UV rays are: Ocular dryness and oxidative reactions to the conjunctiva Yellowing and loss of transparency of the lens Damage to the corn Ultraviolet (UV) radiations are in the invisible region of the electromagnetic spectrum, between 100 nm and 400 nm, and they are divided into three bands (UVA, UVB and UVC) based on biological effects. The UV-C rays are absorbed at 100% by the Earth's electromagnetic field; the UV-B rays are absorbed at 95% by the terrestrial and ozone sphere electromagnetic field. UV-A rays affect the eye entirely. We are specialized in optical lenses since 1950s in Italy. Now we have steady productions, research, sales, marketing, after sale care and so on. We have past CE, FDA and some other certificate as for the medical device.

Ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, Solar-photovoltaic and fiber-to-detector coupling. Worldhawk can provide spherical ball lenses and half ball lenses in a range of substrates for performance in the ultraviolet to the NIR. Such as including H-K9L(N-BK7), Sapphire, CaF2, BaF2, ZnSe or custom materials upon request. Ball lenses feature short back focal lengths to minimize the distance needed from the ball Lens to the optical fiber. Ball lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications. Half-Ball (hemispherical) lenses are ideal for applications such as fiber communication,endoscopy, microscopy, optical pick-up devices,and laser measurement systems.
Optical sapphire ball lens and half ball lens are both made from Al203, it's ideal for demanding applications (such as laser systems). They have a lot of advantages: 1/ Stronger than standard optical glass,they have extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. 2/ Transmits Wavelengths Ranging From UV to Mid-Infrared (0.2 - 5.5µm.) Materials characteristic Refractive index (nd) 1.768 Coefficient of dispersion (Vd) 72.2 Density (g/cm3) 3.97 TCE (μm/m) 5.3 Soften Temperature () 2000 Knoop hardness (kg/mm2) 2200 About sapphire materials for our ball lenses We only choose the best sapphire material to process the ball lens and hemispherical half ball lenses for our customers. As you know, sapphire has higher performance and higher purity near the center in the process of growing. So only the ball lens made from this part of the material has better performance.

Ensure no harm comes to lenses in the grinding process with our optical lens pads, suitable for all shapes and styles of eyewear. These technologically-developed foam pads have been designed to promote best practices of care when dealing with lens augmentation.Sticky foam pads attach to all models of grinding machine, making our selection versatile for every glasses manufacturer. Avoid costly scratches and machine marks with lens blocking pads, which fix to each side of the lens, holding it securely in place for grinding, without compromising the quality of the glass. With consistently low torque, our optical lens pads allow for accurate edging and, being supplied with non-adhesive tabs, are applied with complete ease and precision.
Condenser lenses are molded lenses designed for illumination applications. Featuring large apertures and short focal lengths, condenser lenses are commonly used in emitter-detector applications, projection applications, or condensing illumination applications such as koehler illumination. The aspheric condenser lenses are molded on the aspheric surface and ground and polished on the opposite face, offering superior performance.

A mirror is an object that reflects light in such a way that, for incident light in some range of wavelengths, the reflected light preserves many or most of the detailed physical characteristics of the original light. This is different from other light-reflecting objects that do not preserve much of the original wave signal other than color and diffuse reflected light.
