Hi everyone, We are planning to integrate the OAK-D Pro PoE (equipped with the OV9782 fixed-focus stereo pair) into a system that will operate concurrently alongside a separate 976 nm laser source. Before we proceed with our hardware layout, we would appreciate it if the community or the Luxonis team could clarify a few technical questions regarding optical compatibility and sensor configurations: **1. Optical Compatibility & Potential Interference** * **Bandpass Filtering:** Does the OAK-D Pro PoE depth system use a restrictive optical bandpass filter centered tightly around 940 nm? Or does it use a wider near-infrared (NIR) transmission window that might pass 976 nm light? * **976 nm Interference:** Is the camera's stereo depth estimation expected to experience noise, artifacts, or matching degradation from continuous-wave (CW) or modulated external illumination at 976 nm? * **Saturation & Sensor Damage:** Is there any documented maximum allowable external optical power or irradiance threshold at 976 nm to prevent sensor saturation or permanent pixel damage? * **NIR Validation:** Has this camera model been tested or validated with external IR sources operating in the 950–1000 nm range? **2. Spectral Response & Documentation** * If available, could you share a spectral response curve for the sensor and/or the transmission curve for the camera's built-in optical filter? **3. Center Camera Hardware Options (OAK-D & OAK-D S2)** * We are also evaluating the standard OAK-D and OAK-D S2 form factors. Is it possible to configure or order these specific models with a Global Shutter RGB camera in the center position instead of the default rolling shutter sensor? Thank you very much for your time, documentation, or validation notes.

OAK-D Pro PoE Optical Compatibility with 976nm Laser

H_Dann

Hi everyone,

We are planning to integrate the OAK-D Pro PoE (equipped with the OV9782 fixed-focus stereo pair) into a system that will operate concurrently alongside a separate 976 nm laser source.

Before we proceed with our hardware layout, we would appreciate it if the community or the Luxonis team could clarify a few technical questions regarding optical compatibility and sensor configurations:

1. Optical Compatibility & Potential Interference

Bandpass Filtering: Does the OAK-D Pro PoE depth system use a restrictive optical bandpass filter centered tightly around 940 nm? Or does it use a wider near-infrared (NIR) transmission window that might pass 976 nm light?
976 nm Interference: Is the camera's stereo depth estimation expected to experience noise, artifacts, or matching degradation from continuous-wave (CW) or modulated external illumination at 976 nm?
Saturation & Sensor Damage: Is there any documented maximum allowable external optical power or irradiance threshold at 976 nm to prevent sensor saturation or permanent pixel damage?
NIR Validation: Has this camera model been tested or validated with external IR sources operating in the 950–1000 nm range?

2. Spectral Response & Documentation

If available, could you share a spectral response curve for the sensor and/or the transmission curve for the camera's built-in optical filter?

3. Center Camera Hardware Options (OAK-D & OAK-D S2)

We are also evaluating the standard OAK-D and OAK-D S2 form factors. Is it possible to configure or order these specific models with a Global Shutter RGB camera in the center position instead of the default rolling shutter sensor?

Thank you very much for your time, documentation, or validation notes.

Hey H_Dann - the OAK-D Pro PoE stereo pair uses 940 nm notch filters. You can see the filter transmittance curve here: filter transmittance curve. Transmission falls sharply above the 940 nm pass band.

We do not publish a guaranteed attenuation value at 976 nm, a maximum allowed external irradiance, or validation results for CW or modulated 950–1000 nm sources. We therefore cannot confirm that a 976 nm laser will have no effect. A high-power source can still cause saturation, depending on its radiance, beam divergence, distance, and angle to the cameras.

OAK-D Pro PoE FF-97 variant, OV9782 is the centre global-shutter colour camera. The stereo depth pair is still two OV9282 mono global-shutter cameras.

The dot projector and flood IR LED are disabled by default. The dot projector improves normal stereo matching on low-texture surfaces; it does not provide a published external-source modulation-rejection method. For a deployment-critical system, please test laser-off versus laser-on with fixed exposure and gain in the final optical geometry, and check both stereo images and depth confidence.

For OAK-D and OAK-D S2, there is no standard global-shutter center-camera variant in the current product options. CCM customisation is possible, if the order is big enough. Please contact support@luxonis.com with the required quantity and target configuration.

Thanks,
Oskar

Hi,
Thanks for confirming
So you are saying the OAK D POE FF-97 can work with lasers having bandwidth of 976nm if the IR dot projector is turned off ?
and since you mentioned that the center camera is customiseable .. for the same OAK D a high res global shutter center camera (color) is possible ??

i was under the impression that the laser might damage the camera sensors ,anyway i wont be using the IR dot projectors so do u suggest i go with the camera ??

Hey H_Dann - turning off the dot projector removes the camera’s own 940 nm light, but it does not confirm that a 976 nm laser is safe or has no effect. The filter should strongly attenuate 976 nm, but we sadly do not have a specified external-laser irradiance limit or 976 nm validation.

The FF-97 has a 1 MP global-shutter colour centre camera. I cannot confirm a standard higher-resolution global-shutter colour option. CCM customisation is possible, but the exact sensor and optics need hardware-team review.

Please send the requested camera specification and size of order to support@luxonis.com.

Thanks,
Oskar
