Single lens is a lens composed of pure single elements, which can be considered as the basic element for developing optical systems. Based on the design of optical engineers, multi optical single lens may be used in the optical system of other optical systems.


As a basic optical element, a Single lens is usually used for engineers' design and further assembly work for various applications such as imaging collimation. Our manufacturing capabilities cover flat convex / concave, double concave, double convex, positive and negative meniscus, and a variety of changes from optical glass and fused silica to Zhi crystals. With our reliable coating technology, AR or V coatings can be applied to achieve the desired results. Special treatment, i.e. edge blackening / special packaging / labels can also be provided on request.

Our Single lens production capacity helps our customers build their unique and Jiandu applications, such as microscope equipment, with a diameter of 2.5mm ~ 3.5mm, which is suitable for projection / observation applications. We can provide single lenses with a diameter of 180 + mm. In addition to conventional visible spectrum single lens, we can also process NIR / SWIR / MWIR / LWIR lens


For the system requirements of fechangjinquemingai, please contact us for more information. Our engineer fechang is willing to evaluate your design and has our manufacturing input help experience to define the appropriate tolerance.

A spherical lens is a reflective surface that is part of a sphere. The surface can be convex or concave. The concave spherical lens has an inward convex reflecting surface and reflects light inward. The convex spherical lens has a reflecting surface convex towards the light source and reflects light outward. The substrate materials of spherical lens include various optical glasses, ultraviolet fused quartz, infrared fused quartz, calcium fluoride (CaF2), magnesium fluoride (MgF2), zinc selenide (ZnSe), germanium (GE), silicon (SI), etc., and provide various optical films such as antireflection film, high reflection film, beam splitting film, metal film, etc. Wide band antireflection film can be used in ultraviolet, visible, near-infrared and mid infrared bands.


Concave spherical lens properties:


1. the reflection of concave spherical lens obeys the reflection law of light.


2. when the light from the spindle is reflected by the concave spherical lens, the reflected light will focus on the focus. The focus of a concave spherical lens is the convergence point of the actual light, so it is the real focus.


3. the concave spherical lens focuses light, and the smaller the focal length, the stronger the convergence ability.


4. four special rays: the rays parallel to the main axis will be reflected by the concave spherical lens and focused at the focus; The incident light at the focal point is reflected and parallel to the principal axis; Along the original path, the incident light of the sphere Zhongxin is reversed; The incident light from the vertex is symmetrical to the reflected light on the principal axis.

Convex spherical lens properties:


1. the reflection of concave spherical lens obeys the reflection law of light.


2. the focus of convex spherical lens is virtual focus.


Convex spherical lens has different effects on light. The smaller the focal length, the greater the divergence.


4. four special rays: (similar to concave spherical lens).


Application of Single lens


A. Use array lens for imaging, used in monitoring, microscope and other fields.


B. Correction of spherical and optical aberrations by glued lens to obtain ideal image quality
