L085-DEVKIT
Brief
L085 is 5.3-130mm focal length (25x) motorized zoom lens is designed for 1/2.7" image sensors, has zoom/focus/iris functions, designed for 5M sensors.
Specifications
Optics

Mechanics
| Flange back (FB, see diagram below) |
-0.325mm (in glass t=0.3 IRCF) |
| Lens zoom structure | The stepper motor is directly connected to the screw |
| Lens focusing structure | The stepper motor is directly connected to the screw |
| Lens size |
|
| Weight | 116g (+controller 7.8g) |
In order to accommodate different image sensors, the focal distance is set back by flange back (FB) distance. The actual distance for a specific sensor has to be calculated and spacers used. If the image plane is not set correctly, focus irregularities in the projected picture are expected.
