Large aperture lenses with high surface quality are demanded for professional imaging products such as single-lens reflex cameras and astronomical telescopes. Large aperture optical lenses are shaped by ultra-precision grinding and finished by prolonged polishing. However, the prolonged polishing process leads to deterioration of the form accuracy.

· Lens making techniques and the internal quality of glass in early times were sufficiently advanced to produce spectacle lenses that used only one to two percent of lens surface to help the eye to focus, but a lens of such diminutive size would not be sufficiently large to serve as the objective of a telescope, a device for "making far objects appear close" that requires higher resolving

Comparing to its predecessor – a single-lens objective (singlet) telescope, which was the dominant astronomical gear from 1608 () to the end of the 17 th century, the new telescopes were much shorter and better quality, as the chromatic aberration was reduced by combination of crown and flint lenses.

This allows me to move the bearing toward and away from the grinder. Only a few minutes of spinning the blank against the spinning grinder wheel gets rid of the rough edges and parting lines, and makes the blanks truly round. A face shield, gloves and high quality dust mask are required for this grinding operation. I only do it outside.

for himself, Christiaan designed and built his own lens-grinding and -polishing machines (Figure 2). One of the greatest problems with lens grinding is to make a suitable lap by utilising metal moulds with a perfect spherical shape. Another problem for the Huygens brothers was to find glass of high quality and homogeneous in structure.

· A reflecting telescope, having no lenses, produces a sharper and cleaner image than a simple refracting telescope. Nevertheless, it wasn't until 1721, more than 50 years after Newton constructed his first telescope, that the English inventor John Hadley succeeded in building a large-scale Newtonian reflecting telescope (and not with Newton's spherical mirror

High quality plastic optics are mass produced by the process of injection molding (Hoff 1995). Liquid plastic is forced into a heated mold cavity at high pressures. The plastic solidifies to the inverse shape of the mold. By carefully controlling the pressure and temperature profiles, high quality lenses up to 50 mm in diameter can be produced.
