L120-DEVKIT

Brief

L120 is 6.7-190mm focal length (28x) motorized zoom lens is designed for 1/1.8" image sensors, has zoom/focus/iris functions, designed for 5M sensors.

Specifications

Optics

Image sensor	1/1.8" Effective image area > 9.3mm

Mechanics

Flange back (FB, see diagram below)	-1.0mm (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	Length: 119mm Width: 50mm Height: 50mm Front end diameter:  43mm
Weight	194g (+controller 7.6g)

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.
