| The discovery of achromatic lenses made of flint and crown glass heralded a new era for telescope makers, but the same did not apply to the microscope. |
|
| Hall used the achromatic lens to fabricate his telescope sometime in the 1730s, but he never publicized his discovery and failed to patent it as well. |
|
| Lens doublets are also known as achromatic lenses or achromats for short, derived from the Greek terms a meaning without and chroma meaning color. |
