1.
Extended or limited operating temperature ranges are available; contact Teledyne DALSA for more
information.
2.
To avoid possible damage, when storing cameras, ensure that the sensor is not exposed to air; use a
lens cap or lens to cover the sensor.
3.
Camera NETD measures the actual noise in output images, using an f/1.0 lens, with processing.
WARNING: These sensors are sensitive to over-exposure to hot objects; the sensors
are considered “sun-safe” in the sense that pixels will not break if over exposed for
short periods; however, long exposure to hot bodies (like the sun) will eventually
create ghost-like artifacts. These artifacts can be made to disappear by recalibrating
Fixed Pattern Noise Correction
).
WARNING: For cameras not equipped with a lens, do not touch the internal
mechanical shutter; any physical contact to the shutter may render it unusable.
