Performance characteristics over recommended operating conditions. Typical values at 25°C, V
Parameter
Path Error (Deviation)
The following graphs (Figures 21, 22, 23, and 24) are the typical performance of the ADNS-2051 sensor, assembled as
shown in the 2D assembly drawing with the HDNS-2100 Lens/Prism, the HDNS-2200 clip, and the HLMP-ED80-XX000
LED (page 3, Figure 4).
Typical Performance Characteristics

surfaces)
Figure 23. Typical resolution vs. z (manila folder
and LED variation)
Note:
1. The ADNS-2051 is designed for optimal performance when used with the HLMP-ED80-XX000 (red LED 639 nm). For use with other LED colors
2. Z = Distance from Lens Reference plane to Surface.
3. DOF = Depth of Field.
(i.e., blue, green), please consult factory. When using alternate LEDs, there may also be performance degradation and additional eye safety con-
siderations.

Notes
Path Error (Deviation) is the error from the
ideal cursor path. It is expressed as a
percentage of total travel and is measured
over standard surfaces.
