| Multi Magnifications Optical Unit |
 |
2 (or more) different magnifications in an optical systems.
Suitable for rough positioning of object by low magnification, and precise positioning by high magnification. |
|
 |
<Example: Dual View Optical Unit>
Used for flip-chip bonding machine etc.
Possible to measure the bonding position from upper view and lower view at once with high degree of accuracy. |
|
 |
f Lens |
|
It is used for constant velocity scanning of laser beam by polygon mirror etc. When the rotational scanning converts into the linear scanning, it is expressed by the relation "y=fx ", therefore it is called fx=f(f- theta) lens. |
|
 |
| Far Infrared (IR) Lens |
|
The mass-production of Silicon, Germanium lens for IR lens is available. Far infrared lenses are used for thermal measurement lens unit etc.
<Manufacturable shapes and diameter of lens>
| Shape |
Bi-convex lens, Bi-concave lens
Convex lens, Concave lens
Meniscus lens |
| Diameter |
5 to 180mm(dia.) |
