Chinese leading moulded aspheric glass lens manufacturer Hay:F06NJMD

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.

Injection molding lens machining

As optics, biomedicine, communication, micro equipments and daily products develop rapidly, the demand of micro component increased year by year, so it's very important to manufacture these micro components in mass production .As an emerging production method which can be used to manufacture micron grade, milligram grade products, micro injection molding technology has attracted a lot of attention from the world, ,it has the follow advantages: low cost, short production period, simple molding technology, easy meeting component quality compared with silicon materials components that currently used in the field of MEMS .

It can use self-developed micro mold to research and product high precision and complex shape components with a variety of polymer materials.In the manufacturing process, using automatic injection molding, be able to carry out the pressure waveform, automatic adjustment of measurement time ,automatic detection finished product and die protecti on work, ensure that manufacture stable quality products in different production environments.

Scope of application:

Optical imaging products ,eg:Cell phone lens, camera lens and so on,Trihedron free-form surface lens, DVD read and write class and others

Optical non-imaging products,eg:Uniform light, auto lamp lens array lens, light guide plate, precision connectors etc.
