Collimating Lenses List

IAdiy designed the collimating lenses for laser collimation of different N.A. comparing different divergent angle. You can check the list below to find as you need. As the Gaussian beam theorem(refer to Wiki), the collimated laser beam spot size is inversely proportional to the divergent angle, for a given wavelength λ, a Gaussian beam that is focused to a small spot diverges rapidly as it propagates away from the focus. Conversely, to minimize the divergence of a laser beam in the far field (and increase its peak intensity at large distances) it must have a large crossection (w0) at the waist (and thus a large diameter where it is launched, since w(z) is never less than w0 ). This relationship between beam width and divergence is a fundamental characteristic of diffraction, and of the Fourier transform which describes Fraunhofer diffraction. If need both small divergent angle and laser spot size you may need considering bigger diameter of collimator lens.

Camera Lens Modules List

IAdiy designed the camera lens modules for different image sensor of different FOV. As our new free form lens design and manufacture ability, we develop the low distortion wide angle camera lens module. The advantage of low distortion and wide angle view is good for the security monitor, image recognition and wide angle sesing applications. You can check the camera lens modules list below to find what you need. The image circle dimension needs to compare to the imsage sensor size usually a little bigger than snesor size. You can consider choosing the bigger image circle diameter of camera lens for your image sensor and compare the suitable pixel resolution to the sensor pixel size. Then you can choose the camera lens FOV or focal length close to your application requirement for the camera module.

Our team of experts in optical design and manufacturing is experienced in developing customized solutions with custom sizes and shapes, specific optical coatings, or any other modification.


Type of LENSES

Referenced below is some helpful technical information including lens types and terminology definitions. Use these guides in addition to the magnifiers recommendations below to help you choose the correct magnifier.


Simple Positive Lens - A single piece of optical glass or acrylic with two convex surfaces (curved outward). Designed for low magnification.


Simple Negative Lens - A single piece of optical glass or acrylic with two concave surfaces (curved inward). Used in conjunction with positive lenses.


Achromatic Lens - A positive simple lens cemented to a negative simple lens.Achromatic lenses are corrected for two colors and produce flatter fields of view at higher powers.


Double Lens - Two simple lenses used as a system but not cemented together. This system produces a far superior image than a simple lens.



Aspheric lenses have one or more optical surfaces of non-constant curvature. They are used to avoid aberrations existing in spherical lens systems, and to reduce the optical systems overall dimensions and weight. One of the benefit of aspheric lenses is to correct the spherical aberration. Spherical aberration happens when focusing or collimating light through a spherical surface: all spherical surfaces will produce such spherical aberration regardless of the alignment or the manufacturing errors. Through the adjustment of the parameters of the lens, such as the conic constant and the aspheric coefficients, the aspheric lenses are designed to minimize the spherical aberration. The throughput of aspherical systems is also improved thanks to additional aberration corrections, thereby achieving low f/# and high numerical aperture values, without decreasing the image quality.

The correction of aberration using aspheric optical systems also allows the use of fewer optical elements than in spherical systems thanks to improved aberration correction compared to the latter. The multiplicity of optical elements in one system has a negative influence on other parameters (both optical and mechanical), thereby decreasing the tolerances and complexifying the alignment procedures, as well as requiring higher quality surface coatings. These influences will affect the systems efficiency, their size and their costs. Therefore aspheric system that may seem more expensive at first would actually be more cost-efficient for your applications.



In order to design an aspheric lens, many parameters need to be specified. We first need the custom aspheric form, that is often mathematically described with the Forbes Q Polynomial (Figure 1) or the Even Aspheric Equation (Figure 2). These equations both require to define the Vertex Radius (I/C), the Conic Constant (k) and Aspheric Coefficients (a). Additionally, a Sag Table is used as a reference to check the compativbility between different manufacturing or metrology tools used.

Replicated Aspheric Lens / Hybrid Optical Lens Replication Process

We use the glass replication technology to manufacture hybrid optics. The process consists in replicating a layer of liquid polymer that is UV curable on a glass surface. The glass replication technology is a cold process that can be performed at room temperature. It is the most flexible and cost effective solution for designing specific optical functions, such as astigmatism, since any kind of shape can be designed on an optical surface thanks to this process.

To sum up: our hybrid lenses combine the quality standards of the glass molded lenses with the cost efficiency of the plastic lenses.



Advantages of Glass Replicated Aspheric Lenses


Free Form Lens

The use of free form lenses can bring many benefits, such as beam shaping, coma corrections, astigmatism or wave front corrections in the optical path. The free form lenses can optimize the coupling efficiency of a laser diode into a fiber thanks to their abilities of converting oval beams into laser round spots. Any kind of shape can be replicated on any optical flat or curved surface. Common free form shapes comprise beam shaping lenses (surface looking like a saddle). Free-form lenses can be produced through glass replica technology for a minimal cost since the most expensive mold required for the master glass lens only needs to be designed once. Our proposes services for plastic molding and two kinds of technology of glass molding and replication process for the manufacture of free-form lenses.

Hello Alaa: As your requirements I suggest considering the laser coupling lens. Or you may can consider CO8FL11.2, the BFL is 9.7mm. If you want better performance you can consider the custom made coupling lens. I need more details about the laser divergent angle, the N.A. of fiber and coupling distance or dimensions you prefer. Thank you.

Greetings! I am contacting you to inquire about M12 camera lenses; as of this moment. I am in need of a camera lens with DFOV: 170, HFOV: 138 and HFOV: 102, or the closest it can get to that (preferably above the specified values and not below) for a 1/2.7" 2MP image sensor of 3um pixel size. The camera also features IR leds for night vision. Any suggestions? Thanks in advance.
