Optics and Illumination

Sensor

Proprietary Color CMOS sensor with global shutter and 844 x 640 pixel resolution; 60 frames per second.

Illumination Wavelength

624 nm Red LED (B/W Sensor) or Broadspectrum White LED (Color Sensor).

Aiming Wavelength

N5680/N5690 Imager: 528 nm visible green LED.
N5683/N5693 Imager: 650 nm high-visibility red laser; maximum output 1 mW Class 2 Laser.

Window Placement

Distance from Window

The window should be mounted as close as possible to the front of the Image Engine (parallel, no tilt). The distance mea-
sured from the front of the imager light gasket to the closest surface of the window should not exceed 1.0mm. Since
unwanted reflections can occur at either surface and the window thickness can vary, the distance from the front of the
imager light gasket to the far side of the glass should not exceed 2.5mm. For windows thicker than 1.5mm, the distance
should be decreased so that the far side of the window does not exceed 2.5mm from the front surface of the engine. If the
glass thickness is increased from 1.5mm to 2mm, the distance from the front of the engine to the near surface of the win-
dow needs to be decreased by 0.5mm to maintain the maximum distance of 2.5mm from the front of the engine to the far
side of the window.

Window Size and Material Requirements

1. Window material must be clear. Clarex (cast acrylic) is preferred. Polycarbonate and CR39 are also acceptable. The
window material should have a hard coating over it to protect it from scratches.
2. A minimum thickness of 0.03 inches (0.762 mm) is recommended for this window, with a maximum allowable thickness
of 0.062 inches (1.57mm). These dimensions prevent reflections from the window that can be seen by the camera.
3. Window clear aperture shown in the following Window Size Diagram is for the location shown. The window size must
increase as it is moved away from the optics module to accommodate the aiming and illumination envelopes shown.
