Aiming System

A 650 nm laser and a DOE generate a laser-aiming pattern which represents the imager's field of view throughout

its entire depth of field. The aiming subsystem uses a visible laser diode, a lens, and a diffractive optical element to

generate the aiming pattern. The pattern's center cross hairs indicates the center of the field of view.

Aiming Pattern

Aiming Error

The aiming pattern is designed to eliminate divergence (parallax) between the aiming axis and the imaging axis.

See Table 3-1 on page 3-1 for Aiming Element specifications.

Aiming Control

The aiming subsystem is under dynamic software control and is independent of the illumination subsystem.

The Symbol SE6700 can capture images with both the aiming subsystem turned on (the image of the aiming

pattern is captured in the digital image) and the aiming subsystem turned off.

Illumination System

An illumination subsystem, consisting of four red 630 nm LEDs, is provided to meet the image capture and

decoding requirements throughout the full range of ambient lighting (total darkness to full sunlight).

Illumination Control

The Symbol SE6700 can capture images with the illumination subsystem turned on or off, accommodating images

that are close to the wavelength of the illumination. For example, since red LED illumination is used, it may be

desirable to shut off the illumination when capturing a printed image in red ink.
