Band-Opitcs has many years of aspherical production experience and owns a variety of aspherical production equipments, providing maximum diameter 500mm to minimum diameter 6mm. Customized optics are produced according to customers’ drawings and requirements of precision.
 
The forms of aspheres are: parabolic aspheres, elliptic aspheres, off-axis aspheres, free-form surfaces, etc. The process can be grind, polish, diamond turning, mould and so on.
 
The applications of our aspherical lenses can be applied for many industries, such as:
 
•  Medical industry: Endoscope, Ophthalmic equipment
•  Laser industry: Laser collimation
•  Semiconductor industry: Wafer vision equipment, Visual radar equipment
•  Aerospace industry: Optical tracking equipment, Optical relay equipment
•  Military industry: Optical analog equipment, High power laser lenses
The Applications Of Our Aspherical Lenses

The Unique Features of Aspheric LensesAspheric lenses, as their name suggests, have varying surface curvatures unlike conventional spherical lenses. This distinct design endows aspheric lenses with superior optical performance, particularly in correcting optical aberrations.Factors Driving the Use o

Aspherical lens applications are transforming the aerospace industry by providing critical optical solutions for demanding environments. These advanced lenses correct aberrations more effectively than traditional spherical lenses, delivering sharper images and enhanced performance. Whether used in E

1.Medical Aspherical Lens technology is transforming how we diagnose, treat, and visualize in modern healthcare. From intraocular lenses to high-resolution endoscopes, the demand for precise, compact, and distortion-free optics is growing fast. In this article, we explore key aspherical lens applic
