L084-DEVKIT

Brief

L084 is 6.3-252mm focal length (40x) motorized zoom lens is designed for 1/1.8" image sensors, has zoom/focus/iris functions, designed for 8M sensors.

Specifications

Optics

Image sensor	1/1.8" Effective image area > 9.2mm
Focal distance	6.3 ~ 252mm / ±5%
Aperture	f/1.4 ~ f/5.0
Focus range	WIDE: 1.0m - infinity TELE: 2.0m - infinity
Field of view (D=8.81mm)	WIDE: 73.0° TELE: 1.9°
Distortion	WIDE: -4.09% TELE: 2.89%
Recommended image sensor	IMX334

Mechanics

Flange back (FB, see diagram below)	+0.93 (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: 168.7mm Width: 72.8mm Height: 57mm Front end diameter: 69.5mm

In order to accommodate different image sensors, the focal distance is set back by 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.
