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. Material : N-SF11H-LaF53H-LaF76 Fused Silicon etc. Radius of Curvaturemm R0.25R Diametermm 0.5 5 Tolerancemm 0.005 0.05 Lengthmm L0.5 L30 Tolerancemm 0.020.06 Thickness tolerancemm 0.01 0.1 Surface Quality 10/580/50 Flaness /20/4 Off centering 110 Optical coating : Upon request
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.

Achromatic lenses are normally made of BK7, fused silica and CaF2. Special focusing systems can be designed by Photonchinaâ??s engineer team. Sizes from smallest diameter of 3mm to biggest of over 100mm are all available. Normal Achromatic Lens Super Small Achromatic Lens Super small Achromatic Lenses for your specific application provide excellent wavefront quality, super small spot size and improved modulation transfer function (MTF). Feature Small diameter size up to 3mm Short focal length, such as 5mm Strict quality control, excellent quality AR-coating, mounts services
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.
Zero Order Waveplate The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. Zero order waveplate shows better performance than low/multiple order waveplates. It has broad bandwidth and a lower sensitivity to temperature and wavelength changes. It should be considered for more critical applications. It is constructed of two low order waveplates with their axes crossed. Thus,the effect of the first plate is canceled by the second,except for the residual difference between them. There are normally three different structures as follows, Optical Contact Cemented by Epoxy Air spaced Low Order Waveplate Low(multiple) order waveplate is designed to give a retardance of several full waves, plus the desired fraction. This result in a single, physically robust component with desired performance. However, even small changed in wavelength or temperature will result in significant changes in the desired fractional retardance. They are less expensive and find use in many applicatios where the increased sensitivities are not an important. Photonchinas waveplates fabrication starts from quartz materials cutting with their axes oriented within a few arcminutes before being polished to a laser-quality finish, arcsecond parallelism, and
