NJMD Precision Optical Technology Corporation is committed to the R&D and manufacturing of ultra-precision Moulded aspheric optical lenses.
Based on advanced micro-nano manufacturing technology and ultra-precision processing technology, the company is engaged in the research and development, production and sales of high-precision optical core components with complex micro-nano structures and related products.
The main products include Moulded aspheric glass lenses, free-form surface optical elements, high-order aspheric glass lenses, complex anisotropic lenses, micro lens arrays and many other series.
Products can be widely used in security systems, automotive systems, automotive systems, laser projection, smart phone modules, semiconductor modules, optical communications, AR/VR, and various intelligent manufacturing equipment, temperature measurement and imaging equipment and other fields.
Aspherical optical lens is a very important optical component. In the optical system, aspherical optical component can correct a variety of aberrations, improve imaging quality, and improve system discrimination. It can replace multiple spherical lenses, thereby simplifying the structure of the instrument , Reduce costs and effectively reduce the weight of the instrument, and obtain the unparalleled imaging quality of spherical optical lenses.
NJMD has been deeply involved in aspheric molding technology for many years, which can meet the mass production and quality requirements of aspheric lenses.
