The Powell Lens can be widely used in alignment, machine vision systems, construction and process control fields. Worldhawk are professional supplier for powell lens, in fact, we have already become the one of the main important suppliers of powell lenses in China. cooperation with us , you will get high quality products with reasonable price and products performance at the same time These Laser Line Generator Lenses, also known as Powell lenses, generate a straight, uniform laser line by fanning out a collimated beam in one dimension, as shown in the diagram above. The apex of each lens features an aspheric curve that evenly distributes the optical power, resulting in an intensity variation of less than 25% over the center portion of the line. You will get more even energy distribution along the laser line than using the rod lenses and lenses.

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.

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 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.
