LC1917

Low-Profile Analog Line Scan Camera

pixel 1024. This dark offset allows the

user to adjust the standard 0 V signal

±100 mV.

Additionally, the LC1917 camera

features a user-adjustable video gain,

allowing for video gains of up to 2.5X.

Video gain is adjustable using the

potentiometer, located underneath the

set screw on the body side adjacent to

the active pixel 1 side of the camera.

Both the gain and offset potentiometers

can also be adjusted by removing the

bottom plate of the camera. This is

accomplished by removing the two

lower screws on both the faceplate

and rear body of the camera. The cam-

era bottom is not attached to any

internal circuitry.

Proper ESD precautions should be

taken when removing the bottom plate

of the camera. Failure to do so can

result in camera failure.

User Connections

The connector on the LC1917-series

camera is a 26-pin high density male

AMP C-216297. All user connections

are via this connector. It contains all

communications, output, and power

connections needed for camera opera-

tion. Refer to Table 1 for pinout locations

and details. Connector pin locations

are shown in Figure 4.

Optical Interface and Mounting

The LC1917 is to be mounted to the

user’s optics via 4 M3 threaded screws,

located on the front panel of the

camera, adjacent to the sensor.

The optical surface of the sensor is

located 2.7mm (±10%) from the surface

face of the camera. The sensor has a

maximum angular error of ±15

milliradians.

Camera Performance

The camera head is housed in a

rugged aluminum case, measuring

0.75”H x 2”W x 3.077”L (excluding

connector extensions) specifically

designed for close-proximity harsh

industrial applications. The sensor is

mounted on an aluminum plate that

efficiently transfers heat to the camera

case. The conductive cooling of this

surface is useful in minimizing ther-

mally generated dark current and

noise of the camera system.
