Page 1 of 2 - Manually grinding a lens - posted in ATM, Optics and DIY Forum: Hello, I'll start to grind a lens with a photographer friend who wanted after years of photography to make one himself to get a feel of the process. The first one will be made in a schott mirror blank, 102mm/15mm thick, and will be plano-convex. We don't expect it to give diffraction limited …
An eyeglass lens grinding machine is primarily used for processing a lens in such a manner that the lens is appropriately adjusted in an eyeglass frame where the edge thickness is great to achieve a good aesthetic appeal. In the improved eyeglass lens grinding machine, the frame's configurational data to be used in providing a layout of the ...

Figure 2: Lens-grinding machine of Christiaan Huygens (From his 'Opuscula Posthuma', published posthumously by Janssonio Waesbergios, Amsterdam, 1728 ) What made it very difficult to produce usable lenses, as the Huygens brothers soon found, was that the whole art of lens grinding was surrounded by secrecy.
Canon has achieved an overwhelming level of machining precision, including the ability to grind a lens surface to a tolerance within 100 nm (nanometers) 3, then polish it to an even higher degree of precision, reducing surface roughness reduced to within a 1 nm range.
Grinding aspherical elements is very difficult if you don't want to leave extremely ugly circular marks that end up showing in the oof highlights. Those are the reasons why I sold the first 3 Otus. The 100mm f1.4 is mostly free of them and so is the Nikon 58mm f0.95 Noct. Another example of a lens ruined by those marks is the Canon 28-70mm f2.0.
CIOE - Precision Optics, Lens & Camera Module Expo is the leading optics exhibition in Asia attracting 850+ leading optics companies around the world to exhibit, presenting the entire optics supply chain including optical components and materials, machine vision and industrial application, imaging measurement and instrument, optical processing equipment, optical …
Vertex Optics has state-of-the-art grinding and polishing machines as well as optics professionals with decades of experience manufacturing freeform optics. For freeforms up to 150mm, rough and fine grinding of the surface is performed on the OptiPro eSX 150 CNC optical grinding machine. For freeforms up to 300mm, the OptiPro OptiSonic 550X is ...
Over the next several decades, lens-grinding and polishing techniques improved gradually. A specialized craft community of telescope makers slowly developed. These craftsmen worked to produce better spherical lenses with decreased curvature (and a longer focal length ) which improved the quality of telescopes but made them longer.
Late in 1895, Wilhelm began construction of the first factory building of the Weule Lens Works, which specialized in grinding and polishing glass prisms and other lens elements for Fresnel lenses. The first building was opened on April 1, 1896 and immediately began production.

Optical fiber lens, is a kind of special optical fiber. It is made by grinding the tip of the fiber into the shape of a certain lens such as angle-polished, wedge-shaped, and tapered. The optical fiber lens is used to minimize the spot size, change the optical path, or transform the optical mode in the optical system.
Hyperion Optics has more than 40+ custom precision assembly projects ongoing annually, from prototyping to mass production. Our lens assemblies range from microscope objective lenses, expanders, to SWIR/ MWIR/ LWIR lenses, and more.With our reliable optical/ mechanical design capability, we are confident to achieve challenging assembly jobs.
In a traditional cast plastic lens, 80% of the original lens blank material is wasted as the prescription is ground into the blank. With the same amount of material, ARfusion™ can produce five lenses. Grinding the semi-finished blank also requires 50-100 liters of water, which becomes filled with polymeric waste (micro plastic).
Silver Optics Co.,LTD is a Professional optical plastic mold maker and optical components manufacturer; We have years of expertise in meeting technical challenges of all kinds with cost-effective solutions for polymer optics.We cover the entire value chain – from customer demand, the ultra precision optical mold making up to serial production including optical coating.
The lens would then go to the surface finers and polishers to complete the grinding process. Traditional surfacing is limited in the number of customizations of the progressive designs because of the physical constraints of traditional tools. ... Digital surfacing technology allows labs to produce higher quality lenses. Digital surfacing also ...
