Glass is a common material for aspheric lenses. People pick glass because it lasts long and bends light well. These features help aspheric lenses work better and fix image problems. Many glass aspheric lenses use optical glass from brands like Schott, Hoya, and Ohara. Some special uses need fused silica or low-temperature optical glass. The table below shows what makes glass and plastic different:
| Material | Characteristics |
|---|---|
| Glass | Durable, high index of refraction |
| Plastic | Lighter, flexible, less expensive |
Glass aspheric lenses are strong and do not scratch easily. They work well in places with heat or chemicals. The shape of glass lenses helps fix mistakes in images.
Plastic aspheric lenses bend easily and cost less. Makers use many kinds of optical plastics, such as:
Polymethyl Methacrylate (PMMA)
Polystyrene (PS)
Polycarbonate (PC)
Allyl Diglycol Carbonate (ADC)
Plastic lenses are lighter than glass ones. They weigh about half as much as glass. This makes them simple to use. Plastic aspheric lenses can handle hits almost ten times better than glass. They are much cheaper to make, sometimes only one-tenth the price of glass. The refractive index of plastics is between 1.42 and 1.69, which is less than glass. These facts make plastic aspheric lenses good for light gadgets and electronics.
Crystalline materials give aspheric lenses special abilities. Makers shape these materials by diamond turning, grinding, or molding. Some common crystalline materials are germanium (Ge), silicon (Si), zinc selenide (ZnSe), and zinc sulfide (ZnS). These materials are used in infrared and thermal imaging aspheric lenses. The table below shows how different ways of making lenses use crystalline and other materials:
| Manufacturing Process | Materials Used |
|---|---|
| Diamond Turning | Infrared, Silicon, Zinc Selenide, Zinc Sulfide, Plastics |
| Grinding and Polishing | Optical glass, Fused Silica, Plastics, Ge, Si, ZnSe, ZnS |
| Precision Glass Molding | Low Temperature Optical Glass, Plastics |
| Injection Molding | Low Temperature Optical Glass, Plastics |

Doctors and scientists often use glass aspheric lenses. These lenses give clearer images and stay stable. Glass lenses are good for jobs that need high accuracy, like telescopes. Electronics makers usually pick plastic or mixed lenses to save money and still work well.
How you make the lens changes its quality. Diamond turning, grinding, and molding all give different results. Smooth surfaces help light go through and stop scattering. Special coatings can make lenses work better by cutting glare and reflection. Anti-reflective coatings help laser systems and screens work better.
Rules are important for medical and space jobs. For example, ISO 13485 gives rules for making medical devices. FDA 21 CFR Part 820 makes sure things are made well in the US. CE Marking is needed for things sold in Europe. These rules make sure aspheric lenses are safe and work right.
Tip: Always look at the project timeline and sample cost before picking a lens material. If you need lenses fast, plastic is a good choice. If you have more time, glass or crystalline may be better.
What you use the aspheric lens for helps pick the material. Each job has special needs that change which lens is best.
Laser systems need lenses that can handle strong energy and certain light types. Fused silica and S-LAH64 are good for these jobs. How you make the lens also matters. Diamond turning and precision molding help make very accurate lenses for lasers.
Medical tools and science machines need very exact aspheric lenses. Glass materials give the best image quality and stay steady in different places. These lenses help doctors and scientists see clearly and get good results.
Cameras and VR headsets often use plastic aspheric lenses. These lenses are light and do not break easily. Companies can make many plastic lenses quickly, so they cost less. Wearable devices use plastic lenses because they are light and strong.
The table below shows which materials are best for each job:
