Getting Started

Before using the device with students for the first time, perform the following tasks:

1. Charge 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. Select the wireless device that matches your device ID.

4. Press and hold the power button until the battery status LED turns on.

5. Open SPARKvue and select Sensor Data.

6. 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 a dynamics track using the included 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 the track (Figure 2).
3. Slide the Diffraction Scanner to the desired position on the track then tighten the front and rear mounting screws.
   
   Figure 2. Inserting the Diffraction Scanner into an optics track.

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.

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 a narrower slit to improve the spatial resolution.

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
