Spectral Response

IMX249 Spectral Response

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

IR Cut Filter

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

The IR cut filter has the following spectral characteristics:

Wavelength [nm] Transmittance
450–610 Tmin > 90 %
450–620 Tavg > 93 %
645 ± 10 T = 50 %
700–1070 Tmax < 4 %
690–1070 Tavg < 1 %

The filter holder can't be removed.

Electrical Requirements

Danger

Electric Shock Hazard

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

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.

Notice

Incorrect voltage can damage the camera.

  • You must supply camera and I/O power within the safe operating voltage ranges specified below.
  • Do not use negative voltage for an I/O line.

Camera Power

Notice

Dual camera power supply can damage the camera.

You must supply camera power either via Power over Ethernet (PoE) or via the camera's I/O connector. Do not use both ways of supplying camera power at the same time.

Opto-Coupled I/O Input Line

Voltage

Description

30 VDC Absolute maximum. This voltage must never be exceeded. Doing so may damage the camera and voids the warranty.
0–24 VDC Safe operating range.
0–1.4 VDC Indicates a logical 0 (with inverter disabled).
>1.4–2.2 VDC Region where the logic level transition occurs; the logical state is not defined in this region.
>2.2 VDC Indicates a logical 1 (with inverter disabled).
  • Minimum current: 5 mA
  • Current draw: 5–15 mA
  • If the camera is connected to a PLC device, Basler recommends using a cable that adjusts the voltage level of the PLC to that of the camera.

Opto-Coupled I/O Output Line

Voltage

Description

30 VDC Absolute maximum. This voltage must never be exceeded. Doing so may damage the camera and voids the warranty.
3.3–24 VDC Safe operating range.
<3.3 VDC Unreliable I/O output.
  • Leakage current: <60 µA. Actual leakage depends on operating temperature and production spread of electronic components.
  • Maximum load current: 50 mA
  • Minimum load current: Not specified. Consider the following:
      • Leakage current will have stronger effect when load currents are low.
      • Propagation delay of the output increases as load currents decrease.
      • Higher-impedance circuits tend to be more susceptible to EMI.
      • Higher currents cause higher voltage drops in long cables.

General Purpose I/O Lines

Notice

Applying incorrect electrical signals to the camera’s GPIO line can severely damage the camera.

Before you connect any external circuitry to the GPIO line, use the Line Mode parameter to configure the line for input or output.

Make sure to apply appropriate input or output signal voltages as specified below.

Operation as Input

Voltage

Description

30 VDC Absolute maximum. This voltage must never be exceeded. Doing so may damage the camera and voids the warranty.
0–5 VDC Safe operating range. The minimum external pull-up voltage is 3.3 VDC.
0–0.8 VDC Indicates a logical 0 (with inverter disabled).
>0.8–2 VDC Region where the logic level transition occurs; the logical status is not defined in this region.
>2 VDC Indicates a logical 1 (with inverter disabled).
  • Current draw (high-level): <100 μA
  • Sink current: Your application must be able to accept 2 mA sink current from the GPIO input line without exceeding 0.8 VDC.

Operation as Output

Voltage

Description

30 VDC Absolute maximum. This voltage must never be exceeded. Doing so may damage the camera and voids the warranty.
3.3–24 VDC Safe operating range.
<3.3 VDC Unreliable GPIO output.
  • Internal pull-up resistor: ≈2 kΩ, with open collector. Many applications will have to provide an additional pull-up resistor.
  • Residual voltage ("on" state): ≈0.4 V at 50 mA and 25 °C  (77 °F) housing temperature. Actual residual voltage depends on operating temperature, load current, and production spread of electronic components.
  • Leakage current: <60 µA. Actual leakage depends on operating temperature and production spread of electronic components.
  • Maximum load current: 50 mA
  • Minimum load current: Not specified. However, consider the following:
      • Leakage current will have a stronger effect when load currents are low.
      • Propagation delay of the output increases as load currents decrease.
      • Higher-impedance circuits tend to be more susceptible to EMI.
      • Higher currents cause higher voltage drops in long cables.
