optical lenses category
A lens is a transparent optical device that alters the curvature of the wavefront of light. It is a device that either converges or disperses light to produce a real or virtual picture. It is widely employed in various sectors, including security, automobiles, digital cameras, lasers, and optical components.
Plano Convex Lenses
Plano-convex lenses are often used to aim and focus monochromatic light sources, bring parallel light sources closer, or turn point sources that move from each other into similar light sources.
Bi-Convex Lenses
When the object and image are on opposite sides of the lens and the image distance to object distance ratio (conjugate ratio) is between 0.2 and 5, bi-convex lenses are used.
Plano Concave Lenses
Plano concave lenses have a negative focal length and a negative spherical aberration, which can be used to counteract the aberrations of other lenses in the system.
Bi-concave lenses
Biconcave lenses have a negative focal length and are suitable for diverging and converging beams. They are also called diverging or negative spherical lenses, often used in optical systems for beam expansion, collimation, projection, and increasing the focal length.
Aspheric Lenses
Aspheric lenses are made with a single element to help reduce the number of lenses in an optical system. Aspheric lenses allow optical element designers to fix aberrations with fewer optical elements than they would have to use with spherical lenses.
Achromatic Lenses
Achromatic lenses are designed to compensate for the dispersion of the two materials by gluing the lenses of different materials together, thus reducing the overall chromatic aberration.
Cylindrical Lenses
Cylindrical lenses have a circular cross-section with a flat surface and a curved surface on the other. This shape causes the lens to focus light in a line rather than a point, making it useful for applications such as barcode scanning and laser printing. Cylindrical lenses are commonly used in conjunction with spherical lenses to correct for distortion in images.
Meniscus Lenses
Meniscus lenses reduce spherical aberration better than convex lenses, resulting in a minor focal point and less aberration for better image quality.
Ball Lenses
Ball lenses are tiny diameter optical glass beads used to improve the signal coupling between the optical fiber, the transmitter, and the detector and to improve signal quality.
Drum Lenses
Drum lenses have a shorter focal length and greater magnification than ordinary convex lenses, the focal length of which depends on the material’s refractive index and are mainly used in fiber optic applications.
Molded Lenses
Molded lenses are molded in a process that ensures lens consistency and low cost in mass production for applications ranging from targeting systems, barcode scanners, and laser diodes to fiber optic coupling, optical data storage, or biomedical lasers.

K9 optical lenses
K9 optical glass is an optical material with excellent broad-spectrum transmission and high transmission of light at wavelengths from 350nm to 2000nm.
UVFS optical lenses
UV fused silica glass has excellent transmission in the UV band, lower refractive index, better homogeneity, lower coefficient of thermal expansion, higher chemical resistance, and very low fluorescence.
CaF2 optical lenses
The calcium fluoride material has a relatively wide transmission spectrum (180nm-8.0μm), a high damage threshold, low fluorescence, and high homogeneity.
ZnSe optical lenses
ZnSe is a commonly used optical glass material in the infrared band with a transmission band of 600nm-16μm, low absorption, and resistance to thermal shock.
Ge optical lenses
Germanium is a commonly used optical glass material in the infrared band with a transmission band of 2.0-16 μm, a high refractive index, and high Nucleus hardness.
Si optical lenses
Silicon is a commonly used optical glass material in the infrared band with a transmission band of 1.2-8.0 μm. Silicon has high thermal conductivity and can be used as a substrate for many optical components.
optical lenses features
Small batches high precision
We have a lot of optical lenses in stock, but we can also make small batches of high-precision lenses to request for a range of purposes.
Multi-material
Our optical lenses are made with materials from CDGM, SCHOTT, HOYA, OHARA, CORNING, and other companies.
Multi-coating
Our optical coatings are mostly used in the laser, infrared, and classical optics categories and encompass the near-ultraviolet, visible, near-infrared, and far-infrared wavelengths.
Multi-solution
We have cold working and molding procedures to make optical lenses for various applications and client scenarios.
Our Optical Lens Fabrication
Cold Processing
Do you know how cold-processed lenses are produced?
1. to get rid of air bubbles and dirt on the lens’s surface and to shape the lens.
2. Milling the lenses to eliminate the layers that are bad for the lens and fix the R-value.
3. The lenses that have been finely ground are polished again. The main goal of this step is to make the lenses look better.
4. The polished lenses are cleaned of the polishing powder, and the original lenses’ outer diameter is ground to the size requested.
5. One or more layers of tinted or other coatings are put on the lenses.
Molding
Optical glass lens molding technology is a technology used for the processing of high-precision optical components. It involves placing softened glass into a high-precision mold, which is heated, pressurized, and anaerobic in a single direct molding process to produce optical components that meet the requirements.
The most significant effect of this technology is that it has led to a reduction in the size and weight of optical instruments, cost savings, and improved performance and quality of optical imaging.
Optical Lens Applications
Camera Lenses
The most important part of a camera is the lens because the quality of the lens directly affects the quality of the picture taken. It is also one of the most critical ways to divide cameras into different types. In general, you can divide cameras into three groups based on their lenses: professional, semi-professional, and regular. This can be done with both traditional film cameras and digital cameras. There are two main types of lenses: zoom lenses and lenses with a fixed focal length.
Night Vision Devices
Night vision devices are external night sight that operates without an infra-red searchlight to illuminate the target but use the light reflected from the target in low light to be enhanced to a visible image on a fluorescent screen by an image intensifier to observe and aim at the target.
Project Lenses
Projection lenses are replaceable lenses used in professional projectors. Depending on the distance of the projector and the size of the screen to be played, they are classified as short focal length lenses, medium focal length lenses, long focal length lenses, and special scene lenses.
Laser Collimating Lenses
Laser collimating lenses are usually used when the angle of the laser light’s divergence needs to be reduced to make parallel light transmission possible. They have high transmittance and deficient absorption. Customers can get high-quality laser collimating lenses from us that have a high threshold for damage and are used in UV, visible, infrared, and other wavelengths.
