Spectral Response#

onsemi MT9P031 Spectral Response

The spectral response curve excludes lens characteristics, light source characteristics, and IR cut filter characteristics.

IR Cut Filter#

The camera is equipped with an IR cut filter. The filter is mounted in a filter holder inside the lens mount.

The IR cut filter is manufactured by Fujita Electric Works Ltd. and has the following spectral characteristics:

Wavelength [nm] Transmittance
420–600 Tmin ≥ 90 %
Tavg ≥ 92%
650 ± 10 T = 50 %
700–1000 Tavg ≤ 1 %
1000–1100 Tavg ≤ 5 %

Environmental Requirements#

Temperature and Humidity#

Housing temperature during operation 0–50 °C (32–122 °F)
Housing temperature during storage -20–80 °C (-4–176 °F)
Humidity 20–80 %, relative, non-condensing
Storage humidity 20–80 %, relative, non-condensing
Housing temperature according to UL 60950-1 max. 70 °C (158 °F)
Ambient temperature according to UL 60950-1 max. 30 °C (86 °F)

Electrical Requirements#

WARNING – Electric Shock Hazard

Unapproved power supplies may cause electric shock. Serious injury or death may occur.

  • You must use power supplies that meet the Safety Extra Low Voltage (SELV) and Limited Power Source (LPS) requirements.
  • If you use a powered hub or powered switch, they must meet the SELV and LPS requirements.
WARNING – Fire Hazard

Unapproved power supplies may cause fire and burns.

  • You must use power supplies that meet the Limited Power Source (LPS) requirements.
  • If you use a powered hub or powered switch, they must meet the LPS requirements.

Camera Power#

You must supply camera power that complies with the Universal Serial Bus 3.0 specification.

The camera's nominal operating voltage is 5 VDC, effective on the camera's connector.

Cable Requirements#

  • Use a high-quality USB 3.0 cable with a USB 3.0 Micro-B plug.
  • Do not use cables with a USB 1.x/2.0 Micro-B cable plug, even if you are connecting the camera to a USB 2.0 port. Otherwise, the camera may not work properly.

    Cable Recommendation

  • To avoid EMI, cables must be shielded, as specified in the USB 3.0 standard.

  • Basler recommends using USB 3.0 cables from the Basler cable portfolio.

For more information about recommended USB 3.0 cables, see the Recommended Accessories for Basler USB 3.0 Cameras document.

USB 2.0 Compatibility#

All Basler pulse USB 3.0 cameras are USB 2.0 backward compatible.

However, performance is limited when connected to a USB 2.0 port:

  • In order to handle the lower USB 2.0 bandwidth, the DeviceLinkThroughputLimit parameter value is set to 32 000 000 (32 MByte/s).
  • This reduces the maximum possible frame rate.
  • This also affects other aspects of the performance, e.g., the sensor readout time, trigger delay, jitter, or the precision of the exposure time set.
  • If you operate a puA1280-54um/uc camera module on a USB 2.0 port, image noise may increase. This is because the image sensor produces more image noise at low frame rates. To reduce image noise at low frame rates, try the following:

For information about suitable USB 2.0 host controllers and about optimizing the USB 2.0 data transmission rate, see the Recommended USB 2.0 Host Controllers for Basler dart and pulse Cameras application note.

Physical Interface#

Camera Connectors

USB 3.0 Connector#

The camera's USB 3.0 connector is a standard Micro-B USB 3.0 connector. It provides a USB 3.0 connection to supply power to the camera and to transmit video data and control signals.

Connection assignments and numbering adhere to the Universal Serial Bus 3.0 standard. The recommended mating connector is a Micro-B USB 3.0 plug.

Tripod Socket#

All pulse cameras are equipped with a tripod socket to attach the camera to a tripod. The socket has a standard 1/4-20 UNC thread.
