In addition, because the surface shape of an aspheric lens is designed and formed to effectively reduce aberration in specific applications, custom aspheric lenses make flexible solutions to complex problems.

In addition to reducing spherical aberration, aspheric lenses also correct other image distortions, such as astigmatism. Aspheric lenses have been used for many years to reduce spherical aberration and improve the performance of optical systems, but past high cost made them impossible to be used in real-life applications. Recent manufacturing advances in aspheric grinding and polishing have enabled subaperture polishing and produce high-precision aspheres at affordable costs. A single, more affordable, high-performance aspheric lens can replace multiple spherical lenses resulting in the same or sometimes better performance, leading to lighter weight, more compact, and less complex systems at a cost-effective solution that was not possible years before. Read more about these innovative optical lenses below. Aspheres Manufacturing Tolerances

Daheng Imaging tests every machine vision camera before leaving the factory, whereby quality is guaranteed. The industrial cameras have to withstand a 7-day aging test in warm and cold temperatures and a 72 hour during full load test. This allows GeT Cameras and Daheng Imaging to offer a 3 year warranty. The industrial cameras are CE certified by TUV Rheinland, making sure we meet and exceed the European quality standards. Daheng Imaging has a proven track record of product life cycle management (longevity). At this time it is still possible to buy the first developed machine vision camera of Daheng Imaging. Therefore, Daheng Imaging is not only well-recognized in the market, but is also a prominent supplier of machine vision cameras.

Aspheric lenses are optical components with non-spherical surfaces, unlike traditional spherical lenses. They are crucial in correcting aberrations and enhancing image quality across various optical systems. Here, we delve into the significance of aspheric lenses, their manufacturing processes, and their diverse applications.

As the name suggests, an aspherical lens is a lens with a shape other than that of a regular sphere or cylinder. These lenses, which come in a variety of shapes, are used to correct spherical aberration and enhance image quality. Spherical aberration is a type of defect that occurs when light passes through a spherical surface. Depending on how close to the edge it enters the lens, light focuses at different distances, creating a blurry image. In comparison, aspheric lenses focus light to a single point, regardless of where the light ray enters, to reduce or entirely eliminate blurriness from the image.

With a unique aspheric lens design to focus light to a single point, aspheric lenses offer higher precision and image quality compared to simple lenses. At Shanghai Optics, we have more than 55 years of experience providing high quality precision optical lenses to businesses around the world.

Why choose GeT Cameras as your machine vision camera supplier? Our industrial cameras are very affordable, due to our smart business model, which for example includes low margin per product. We offer a single machine vision camera at a low price, because we believe that you will order more machine vision cameras in the future from us. Our Unique Selling Points are:

Like other kinds of optical lenses, aspheres can be produced in a number of ways. At Shanghai Optics, we use two main methods to produce custom aspheric lenses: molding and traditional polishing with the state-of-the-art manufacturing and metrology equipment. To mass produce aspheric lenses that require a lower level of precision, we use lens molding. In this method, we pour the heated lens material into custom molds, where they firm up and take their final shape. To ensure success, we make moldable aspheric lenses out of materials with low transformation temperatures, such as acrylic, plastic, BK-7, B270 and Pyrex. Molded aspheric lenses are the most cost-effective type of asphere. For large silicon aspheric lenses that require a higher level of precision, we turn to a traditional polishing method. With high-speed polishing equipment, we shape and refine precision aspheric lenses quickly while adhering to exact specifications. S.O. can manufacture lenses with best-fit-sphere deviation between a few millimeters and a few waves. Though the manufacturing process you choose will depend on your project requirements and the volume of lenses you require, you’ll find that our molded and polished lenses meet the highest expectations. Our production staff follows ISO 9001 standards and uses cutting-edge metrology equipment to take accurate and repeatable testing measurements.
