Micro Spherical Lenses
Under the condition of high refractive index, some optical components can achieve short focal length. Therefore, the micro lens becomes an ideal choice in the field of high precision applications.
Through years of accumulated processing know-how technologies and production capacity, high standard thin film coating performance and strict testing requirements, Photonchina provides customers with one of the world's smallest but excellent micro lenses products, which have been widely used in various medical devices (endoscope lens, for example), precision surveying and optical communications instruments.
From design, manufacturing to optical coating, from endoscope lens, capsule lens to special-required rod lens, from single mini lens to glued lenses system, engineers in Photonchina implement strict production process to ensure stable quality, competitive price as well as responsive lead time.
A variety of optical glass or other materials, such as BK7, N-SF11, H-LAF76, Fused Silica and so on are available for customers design. H-LaF53, for instance, has often been used in endoscope lens or capsule lens production. We have a wide range of lenses in shape: convex, concave, biconvex, meniscus etc.

Photonchina produces the smallest rod lenses for customers at home and abroad.
Micro rod lenses: 0.5-1.8mm diameter, 1.0-25mm length, with one end of designated curvature radius and another end of arbitrary angle.
Both ends of arbitrary radii or angle are also available. Highly customized products for a wide range of applications from medical device, fiber communications, optical display and surveying equipment.
What is more, we can provide unique rod-shaped glued lenses by combining special gluing/cementing technics and edging skill. These glued/cemented rod lenses subassembly can be made of up to four single micro rod lenses with various combination. Rod lens assembly systems are able to provide images with greater brightness, contrast and color reproduction than conventional lenses.
Rigid endoscope, for instance, which usually has a series of high-resolution optical glass rod lenses, can be forward viewing (0 degrees) or angled (10120 degrees) to allow visualization out of the axis of the telescope and increase the FOV by rotating the instrument. The optical quality of lens-generated images of rigid endoscopes still surpasses that of the fiber-optic or digital images produced by flexible scopes.
High performance optical coatings for rod lenses are provided.
Optical glass material NBK7, N-SF11 from Schott, Corning 7980 etc, are all available.

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.

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.
