Features |
PAMS-1000 lens has tunable focal length characteristics
equivalent with a capacitor electrically, which needs an a.c. voltage
to drive. The changes in focus are made by changing the voltage (Vrms).
The voltage has to be maintained for keeping the lens at a given
focal length.
Due to the Varioptic’s electrowetting technology and it’s
totally protected numerous patents, DN-1000 opens new horizon of
optics industry together with glass and plastic material based conventional
lenses. |

Typical application
Description |
|
|
| With only adding PAMS-1000 as cover lens like the system,
lens will get function enhancement of autofocus. The overall MTF
degradation is very little in the total optical system. The simulation
result also available.§ |
