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.

Micro silica also known as fume, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 mm. The main field of application is as pozzolanic for high performance concrete because of its extreme fineness and high silica.
Applications :
Silica is added to Portland cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance. These improvements stem from both the mechanical improvements resulting from addition of a very fine powder to the cement paste mix as well as from the pozzolanic reactions between the silica fume and free calcium hydroxide in the paste.
Advantages :
Addition of silica also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges.

Spherical Lens
Spherical lens, also known as a single lens, is an optical lens with a curved surface that converges or diverges light. They are widely used in imaging applications. Conjugate ratio, lens shape, radius of curvature, lens material, transmittance, wavefront aberration, scattered light, and type of coating are all features that must be considered when selecting a lens.
Types of Spherical Optics
There are two main types of spherical lenses: concave and convex. Concave lenses are thinner at the centre and thicker at the edges, while the opposite is true for convex lenses. At HS Optics, we routinely produce both types of spherical optics for a variety of imaging applications. The different formats we produce include:
Poly lenses are called convex lenses. It is thicker at the centre than at the edges. Convex lenses come in several shapes and sizes depending on how they look and work:
1. Plano-convex lenses
2. Double-convex lenses
3. Meniscus lens (concave-convex lenses)
Concave lenses. Thinner at the centre than at the edges. Concave lenses can be classified as follows:
Spherical lenses are solid or hollow glass beads with a diameter of several micrometers to tens of micrometers. The application fields involve the chemical industry, military industry, aerospace, transportation, petroleum, light industry, medical treatment, etc.

Positive focus length. Most suitable where one conjugate is more than five times the other, e.g. in sensor applications or for use with near collimated light. Also where both conjugates are on the same side of the lens, e.g. as an add-on lens to increase the numerical aperture.
Most suitable where the conjugates are on opposite sides of the lenses and the ratio of the distances is less than 5:1, e.g. as simple image relay components.
Negative lens with the form most suitable where one conjugate is more than five times the other, e.g. producing divergent light from a collimated input beam.
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.
Optical lenses are essential elements in many optical components, primarily used for imaging, focusing, collimating, and diffusing beams. They affect the wavefront curvature of light and can either converge or diverge light, producing real or virtual images. These lenses are widely used in high-tech fields such as security, digital cameras, high-power lasers, and optical instruments.
Bena Optics currently operates two machining systems: high-speed polishing and classic polishing. High-speed polishing is mainly used for batch commercial products, while classic polishing is employed for repairs, large sizes, specific material requirements, and other special circumstances. Additionally, classic polishing serves as a pretreatment for aspherical surface processing. This dual approach allows Bena Optics to meet diverse customer needs and maintain high-quality standards across various applications.
Key Features of Spherical Lens
A spherical lens has a uniform curvature across its surface, making it widely used in optical devices like telescopes, microscopes, and camera lenses. Key features include:
Uniform Light Refraction: Acts as a collection of infinite prisms, providing uniform convergence and divergence of light, enabling image formation.
Imaging Quality: Spherical lenses have spherical aberration, where light passing through the center and edges focuses at different points, limiting high-precision imaging applications.
Application Range: Due to low cost and simple manufacturing, spherical lenses are widely used in various optical devices, especially in low-cost consumer products.
Additionally, spherical lenses are uniquely applied in coupling between optical fibers, lasers, and detectors, and in collimating fiber beams in dense wavelength division multiplexing (DWDM) systems.
The Applications of Spherical Lens
Spherical lens is used for in various optical devices for focusing, collimating, or expanding light, and forming images. Their applications span metrology, microscopy, aerospace, medical technology, laser systems, and security.
