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, multiple optical single lenses may be used in optical systems of other optical systems.
As a basic optical element, single-line lens is usually used for engineers’ design and further assembly work, for various applications such as imaging collimation. Our manufacturing capacity covers a variety of changes from flat convex/concave, double concave, double convex, positive and negative meniscus, from optical glass, fused quartz and even crystal. With our reliable coating technology, AR or V coating can be applied to meet the expectations. 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 high applications, such as microscope equipment, with a diameter of 2.5mm~3.5mm, which is suitable for projection/observation applications. We can provide 180+mm diameter single lens. In addition to conventional visible spectrum single lens, we can also process NIR/SWIR/MWIR/LWIR lens
For very precise and sensitive system requirements, please contact us for more information. Our engineers are very happy to evaluate your design and have our manufacturing input help experience to define the appropriate tolerance.
A spherical lens is a reflection surface of a 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 convex reflecting surface facing the light source and reflects light outwards. The substrate materials of spherical lens include various optical glass, ultraviolet fused quartz, infrared fused quartz and calcium fluoride (CaF2), magnesium fluoride (MgF2), zinc selenide (ZnSe), germanium (Ge), silicon (Si), etc., and various optical films such as antireflective film, high reflective film, beam splitting film, metal film, etc. are provided. Wideband antireflection film can be used in ultraviolet, visible, near-infrared and mid-infrared bands.
Concave spherical lens attribute:
1. The reflection of concave spherical lens obeys the reflection law of light.
2. When the light from the main axis is reflected by the concave spherical lens, the reflected light will focus on the focus. The focus of the concave spherical lens is the convergence point of the actual light, so it is the real focus.
3. The smaller the focal length is, the stronger the convergence ability is.
4. Four special rays: the rays parallel to the main axis will be reflected by the concave spherical lens and focused on the focal point; The incident light at the focus is reflected and parallel to the main axis; Along the original path, the incident light at the center of the sphere is reversed; The incident light from the vertex is symmetrical with the reflected light on the main axis.
Convex spherical lens attribute:
1. The reflection of concave spherical lens obeys the reflection law of light.
2. The focus of convex spherical lens is virtual focus.
3. Convex spherical lens has different effects on light. The smaller the focal length, the greater the divergence ability.
4. Four kinds of special light: (similar to concave spherical lens).
Application of spherical lens:
A. Use array lens for imaging, for monitoring, microscope and other fields.
B. Correct spherical and optical aberrations by gluing lens to obtain ideal image quality.
