Lenses are the most common form of optic, and a key development moving the optics field along has been the creation of stock lenses.    It can take a great deal of money to develop the tooling and do the design work for a lens, and if that lens is only used by one customer it loses some value.   However, if a stock lens is created in advance, then the cost of the tooling is borne by many customers and so a few of these lenses don't have to cost an arm and a leg and they can be shipped quickly, often within the same day.   

Nalux can make stock lenses that are smaller than 1 mm in diameter, sometimes just tens of microns in diameter, and these are called microlenses and can go into some of the most sophisticated equipment in the world such as the Subaru telescope in Japan.   Nalux can make single individual stock lenses from glass to very exacting tolerances and these stock lenses can be used in applications such as biodetection equipment for security devices.  Or Nalux can make millions of plastic stock lenses for mass market applications such as the large f-theta lenses (see picture in upper left hand corner of this page) which are half an inch thick and 7 inches long and are used in office printers and copiers.  
Nalux can also make them out of some very exotic materials.  One area where Nalux is a recognized leader is in ultraviolet applications.  Many materials that look clear to the naked eye because they let visible light pass through are not clear to the UV light that we can see.  In other words, to visible light many materials are a window but to UV light they are a black wall.  Nalux has learned how to work with a variety of UV materials, both glasses and plastics, enabling high energy optical systems because UV light is very energetic. 

Stock lenses can also take many forms.  They can be perfectly spherical and most applications fit this description.  They can be aspherical, meaning that the surface does not possess a constant radius but that the radius of curvature changes depending on the distance away from the optical axis.  Stock lenses can be more free form or torroidal (saddle shaped) providing optical correction.  They can by cylindrical which is beneficial for laser beam shaping.  There can be diffractive stock lenses which do their focusing by using the principles of constructive and destructive interference to bring light to a focus.  There can be fresnel stock lenses, which is a lens that has been telescoped down onto itself.  
Stock lenses are also made by a variety of processing methods.  Mask lithography, diamond milling, and focused ion beam ablation are all used to make very accurate microlenses.  Diamond turning is used to make very high quality individual stock lenses out of plastics.  Plastic injection molding is used to make all kinds of stock lenses.  No matter the type of optic, Nalux has the equipment and expertise to help you with your next project.
