Getting Started
Before using the device with students for the first time, perform
the following tasks:
1. Change the battery.
2. Update your PASCO data collection software.
3. Update the firmware.
To charge the battery
1. Connect the micro USB cable to the micro USB port on the
Diffraction Scanner. Connect the other end of the cable to a
USB charger or port.
2. Allow the battery to charge for at least three hours. The
battery status LED will turn green when fully charged.
Charging automatically stops when the battery is fully charged.
The device can remain connected to a power source when fully
charged without damaging the battery.
To update PASCO data collection software
1. Open the PASCO data collection software.
2. The software will display a message if an update is
available. Follow the instructions on the screen. If you do
not receive a message, the software is up to date.
You can also check for an update by doing the following:
Go to the Help menu, then click Check for Updates.
Select the menu icon and select Check for Updates.
To update the firmware
The device contains firmware that controls how it functions. It is
important to make sure that your device has the latest version of
the firmware installed.
1. Connect the device to your software. It is recommended to
use a USB connection, since this will result in a faster
update.
2. The software will prompt you if a firmware update is
available. Follow the instructions on the screen if prompted.
If you do not receive a prompt, the firmware is up to date.
Connecting to Software
The device can be connected to software using USB or
Bluetooth.
To connect using USB
1. Connect the device to a computer using the USB cable.
2. Open your PASCO software. The device automatically
connects with the software.
To connect using Bluetooth
1. Press and hold the power button until the battery status
LED turns on.
2. Open Capstone and click Hardware Setup.
3. From the list of available devices, select the wireless device
that matches your device ID.
1. Press and hold the power button until the battery status
LED turns on.
2. Open SPARKvue and select Sensor Data.
3. Under "Connected Devices", select the wireless device that
matches your device ID.
Experimental Setup
The Diffraction Scanner is designed to be used with a PASCO
laser, diffraction slits, and track (see Required Equipment). The
Diffraction Scanner can be mounted to an optics track, or to a
dynamics track using Dynamics Track Optics Carriages. The
setup works best when the Diffraction Scanner is mounted at
least 1 meter from the diffraction slits (Figure 1).
Figure 1. Setup with laser and diffraction slits.
To mount to an optics track
1. Loosen the mounting screws without removing the nut or
the screw from the apparatus.
2. Insert the square nuts into the center slot of the optics
track, with the aperture facing toward the track (Figure 2).
3. Slide the Diffraction Scanner to the desired position on the
track, then tighten the front and rear mounting screws.

To mount to a dynamics track
1. Loosen the mounting screws without removing the nut or
the screw from the apparatus.
2. Insert the front square nut into the center slot of a
Dynamics Track Carriage, then tighten the front mounting
screw (Figure 3).
3. Insert the rear square nut into the center slot of another
Dynamics Track Carriage, then tighten the rear mounting
screw.
4. Snap the Dynamics Track Carriages on the desired position
on the track with the aperture facing the opposite end of the
track.
Use the two remaining Dynamics Track Carriages to mount the
laser and diffraction slits to the dynamics track.

Carriages.
Taking Measurements
The Wireless Diffraction Scanner combines a position sensor
with a light sensor for scanning diffraction patterns. PASCO
Capstone or SPARKvue are used to plot light intensity versus
position of the diffraction pattern.
NOTE: It is also possible to set the Wireless
Diffraction Scanner to remotely log data while not
connected to the computer, allowing the stored
data to be accessed later. For more information
on data logging, see the PASCO Capstone and
SPARKvue online help.
Light Intensity
The Diffraction Scanner contains a slit aperture centered on a
white screen. The width of the aperture can be changed to
control the spatial resolution and amount of light entering the
light intensity sensor. Six apertures of different widths are
installed on a wheel inside of the Diffraction Scanner casing
(Figure 4). The approximate widths of the apertures are 0.1 mm,
0.2 mm, 0.3 mm, 0.5 mm, 1.0 mm, and 1.5 mm.
Change the aperture width by turning the aperture knob. Select
a wider slit to allow more light into the sensor, or select a
narrower slit to improve the spatial resolution.
Figure 4. Aperture wheel inside the Diffraction Scanner casing.
NOTE: It is possible to adjust the sensitivity of the
light sensor using Capstone. Upon connecting to
the device, select the gear icon next to
"Diffraction Intensity Sensor". This will open the
Properties menu, which includes the option to set
the sensor to High, Medium, or Low sensitivity.
Position
The light sensor is mounted on a track that can move laterally by
turning the crank on the side of the Diffraction Scanner. The
position is measured by a rotary encoder attached to the crank.
To obtain the best data, turn the crank at a slow rate.
