Micro Lens (Ultra small lens)
Because of the ultra-small size of this kind of lens (outer diameter 0.5mm-5mm, length: 1mm-20mm), micro lens or ultra-small lens often requires special processing technology, unique production know-how and special optical fixture, etc.
Photonchina provides various sizes of micro lens with an array of applications including active devices, wavelength division multiplexer ( WDM) and fiber lasers (see C-lens, G-lens) in fiber communications, endoscopy for medical and industrial use, capsule endoscope, etc. Its new application fields are still expanding.
A variety of optical glass or other materials, such as N-SF11, H-LAF76, Fused Silica and so on are available for customerâ??s design. H-LaF53, for instance, has often been used in endoscope lens or capsule lens production. The outer diameter of micro lens covers 0.5mm to 5.0mm with any radius of curvature that can be made. We have a wide range of lenses in shape: convex, concave, biconvex, meniscus etc.
Photonchina can provide unique rod-shaped glued lens by combining special gluing technics and edging skill. This rod lens has excellent eccentricity and clear aperture index. From design, manufacturing to optical coating, from endoscope lens, capsule lens to special-required rod lens, engineers in Photonchina implement strict production process to ensure stable quality, good yield, competitive price as well as responsive lead time.

Other situations of which need the infrared detection in hermitic environment.
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.

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
beyond. Our sole aim is to improve the lives of our customers.
We seek to inspire and innovate, which is why we promote a
culture of research within our company.
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
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.
