| Multi-Magnification Optical Units |
 |
Two (or more) different magnifications in one optical system.
Suitable for rough positioning of object by low magnification, and precise positioning by high magnification. |
|
 |
Example: Dual view optical units
Used for applications such as flip-chip bonding machines.
Enables measurement of the bonding position from upper view and lower view at once with a high degree of accuracy. |
|
 |
f Lenses |
|
Used for applications such as constant velocity scanning of laser beams with polygon mirrors. When the rotational scanning converts into the linear scanning, it is expressed by the relation "y=fx ", therefore it is called a fx=f(f- theta) lens. |

 |
| Far Infrared (IR) Lenses |
|
Mass-production of silicon and germanium lenses for IR lens applications is available. Far infrared lenses are used for applications such as thermal measurement lens units.
Possible shapes and diameter of lens

Bi-convex lens, Bi-concave lens
Convex lens, Concave lens,
Meniscus lens |
| Diameter |
5 to 180mm |
