• Manufacturer Part Number: HEDS-1300
• Description: Optical Reflective Sensors
• Manufacturer: HP [Agilent(Hewlett-Packard)]

Preferred Orientation
At maximum signal point (MSP)
and/or when the sensor is in
focus, the orientation of the
sensor is unimportant. However,
as one moves away from MSP
and/or moves out of focus (either
by distance or angle), the pre-
ferred orientation indicated above
is recommended to maintain a
higher resolution spot size.
