Instrumental

To connect to a Thorlabs-DCU224C camera using Instrumental, you can use the following Python script:

from instrumental import instrument, list_instruments

# List all available instruments
print(list_instruments())

# Connect to the Thorlabs-DCU224C camera
cam = instrument('Thorlabs-DCU224C')

# Set camera parameters
cam.exposure = 10  # Set exposure time to 10 ms
cam.gain = 1.5  # Set gain to 1.5
# Capture an image
image = cam.grab_image()

# Display the image
import matplotlib.pyplot as plt
plt.imshow(image)
plt.show()

# Disconnect from the camera
cam.close()

This script first lists all available instruments using the list_instruments() function. Then, it connects to the Thorlabs-DCU224C camera using the instrument() function. It captures an image using the grab_image() method and displays it using matplotlib. Finally, it closes the connection to the camera using the close() method.
