Optical components
Provide the following conditions to keep dirt and droplets out of the optical
system of camera and lens:
• Dust-free environment
• Low relative humidity
• No condensation.
Sensor
Sensors are sensitive to excessive radiation: focused sunlight, lasers, and X-rays
can damage the sensor. Dirt and scratches can damage the sensor, too.
Alvium USB cameras do not need additional cleaning.
Cameras are cleaned before shipping. Incorrect
cleaning can damage the sensor or the filter.
Therefore, never clean the sensor or the filter.
Protect the camera filter and the sensor from dirt,
because dirt becomes more visible the closer it gets
to the sensor. In addition, keep the back lens clean.
Hold the camera with the lens mount facing the
15
ground to keep dirt out of the lens mount.
