Advantages:
The Powell lens has an advantage over cylindrical lenses because later one produces a poorly illuminated line, limited by the non-uniform Gaussian laser beam. Huge spherical aberration redistribute light along the line, decreasing the light in the central area while increasing the light intensity at the lineâ??s end. The outcome is uniformly illuminated line used in all manner of machine vision applications.
1.ZnSe laser focus lenses Widely Used for laser processing,such as cutting,drilling, Welding sculpture,and kinds of laser cutter system.
2.Can Endure High power density,stable coating,Wipe-resistant,two-sided anti-reflecting film, location of 10.6�¼mâ?¥99.5%
3.Optimum design from diffraction and aberration,A series of products have been developed to minimize the diameter of actual focusing spot under the same focal length.
Contrary to popular belief, a super telephoto does not have to be a massive lens, proven here with the Nikon AF-S NIKKOR 500mm f/5.6E PF ED VR. Taking exceptionally long reach and giving it a hand-holdable form factor, this 500mm prime utilizes a unique Phase Fresnel element to greatly reduce the size and weight compared to previous versions of the focal length. This PF element, along with three extra-low dispersion elements, also helps to virtually eliminate color fringing and chromatic aberrations in order to achieve a high degree of clarity, sharpness, and color fidelity. Complementing this advanced optical design, individual elements also feature both Nano Crystal and Super Integrated Coatings to suppress flare and ghosting, as well as a protective fluorine coating to guard the optical system from dust and moisture.
Spanning a long, versatile zoom range, the AF-S NIKKOR 200-500mm f/5.6E ED VR Lens from Nikon is a telephoto zoom characterized by a constant f/5.6 maximum aperture for consistent performance throughout the zoom range. The optical design incorporates three extra-low dispersion glass elements to reduce chromatic aberrations and distortions for increased sharpness and color accuracy. Also contributing to improved image quality, a Super Integrated Coating has been applied to lens elements to lessen flare and ghosting for improved contrast and clarity. A Silent Wave Motor AF system produces fast, near-silent focusing performance that suits both stills shooting and movie recording, which can instantly be manually overridden by simply turning the manual focus ring. Further contributing to photographing in fast-paced situations and difficult lighting, VR (Vibration Reduction) image stabilization compensates for the effects of camera shake by up to 4.5 shutter speed stops. Additionally, an electromagnetic aperture mechanism is integrated into the lens design to provide greater exposure control stability that is especially beneficial when working with faster continuous shooting rates.
A truly versatile wide-angle zoom featuring an advanced optical design and constant f/4 maximum aperture, the Canon EF 11-24mm f/4L USM Lens is a member of the esteemed L-series of lenses designed for full-frame EOS DSLRs. One Super UD element and one UD element offer a significant reduction in chromatic aberrations while four aspherical elements help to minimize distortions throughout the zoom range and provide consistent edge-to-edge sharpness and illumination. Both SWC and ASC coatings have been applied to the elements in order to reduce lens flare and ghosting for increased contrast and color accuracy. Ideally suited for landscape and architectural photography, this lens covers ultra-wide to wide-angle perspectives and backs up its versatile zoom range with sophisticated optical components and intuitive handling.

INTRODUCTION
We are an Italian based company
that creates, produces and operates in the
international market of ophthalmic lenses and
sun-lenses.
At Divel, we value excellence above all else. Whether that's
through our innovative practices, unrivalled craftsmanship or
impeccable customer service, we constantly go above and

OUR MISSION
Our mission is simple; to become the leading destination for
high quality, innovative lenses.culture of research within our
company.
Thanks to the use of latest technology generators, which work with a precision of 0.3 microns, this lens has the ability to offer a more precise vision in all areas needed, and to compensate for any second level errors. Thus, you get a large area close up, and a sharper intermediate zone by adjusting the actual dioptric measurement that of the prescription more consistently.
The lens, which follows all the modern aesthetic standards of internal base flattening, has a variable inset construction, and offers the possibility of modifying the progression channel for each eye. It is, in fact, possible to personalize even further: the morphological and functional differences between right and left handed users.
The Progressive Aurora Clear lenses are supplied in two basic designs that cover the most common uses:
- Ottima, which ensures maximum amplitude of distant vision, especially peripheral, and is ideal for those who spend most of the day outdoors.
- Ampia, which offers a comfortable solution for all situations.
To these designs, we have also added Unica, designed to meet the specific needs of the customer through the optimization of specific parameters provided: right or left handed, pantoscopic tilt of the frame, corneal apex / lens distance, angle of winding of the frame and reading distance. All of these factors make it a custom-built lens, specifically for each customer.
To the classic progressive geometries, we add the Degressive INDOOR (PC & MEETING) geometries, specially designed to provide all the comfort of aurora technology even to those who spend most of the time in closed in spaces, or simply need a pair of glasses optimized for close - intermediate vision.
The economic changes of the beginning of this century have imposed to
modify the DIVEL ITALIA production and its commercial strategies trying to

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.
