Custom CCM

stekla

We ordered quite a lot of OAK-D PRO W. But the latest batches have a 940 band pass filter and only sensitive to visible and 940nm infrared. In our application we need the mono/stereo cameras to be sensitive to 850nm and lower since the medium we are using doesn't work with 940nm.

We have no need for the illuminator since we use an external infrared light source.

I'v been speaking to the sales department and they recommended me posting in this forum.

So for our application we need one RGB sensor, with a DFOV of >= 120 degrees. Better image quality than the one in the OAK-D PRO W would be great if possible.

And we also need two monochrome camera modules for the stereo camera with a DFOV >= 150 degrees and most important sensitive to 850nm.

I had a look at the CCM at https://rvc4.docs.luxonis.com/hardware/platform/sensors/ccms/ but they don't say anything regarding what filters these have.

Could Luxonis provide us with a custom solution or would we able to DIY the solution with the CCM and what camera modules should we then use?

Any input would be appreciated!

There is an option to get a FFC device (like FFC-3P or 4P) and get custom sensors like IMX582 for color since IMX378 is not good enough (?). Though you would need a custom lens as 120DFOV variant is currently not available for the 582. IMX577 would be an option here since it comes with a M12 mount (interchangeable lenses), but the quality might still be a problem - not sure what you are trying to achieve and why you need better than IMX378.

We can provide a custom solution, but MOQ is 100 units AFAIK. The issue is most sensors we sell, are either IRCUT or have a bandpass @940nm since that is what we use on the dot projector/floodlight.

Thanks for the response. Absolutely one option is the use the FFC-3P we already tried it but can't find sensors to fit the needs.

The older OAK-D PRO W was sensitive to 850nm but it change somewhere down the line.

Regarding the RGB sensor, we use the wide camera, that has a the OV9782 which is pretty low quality. The IMX378 would be a big step up but that is only for the non-wide camera.

Would it be possible to get the OV9282 without any filter on it? Or the OV7251?

Arducam have this one that seems to have no ir filter, just what we want but is only for the OAK D camera?

https://shop.luxonis.com/products/oak-ffc-imx378-w has 120DFOV. The OAK-D S2 W variant has either this wide IMX378 or the 9782.

The connector is compatible for OAK-D lite, but will not work on the OAK-D s2 variants. Best to check at Arducam, or if MOQ is high, we can potentially do this as well.

I tried reaching out to Arducam but no response.
I have the OAK-FFC 3P with the OAK-FFC IMX378 W and a pair of with a pair of OAK-FFC OV9282 W.

This setup would work really well for our project if it wasn't for the Bandpass filter @ 940mm.

I tried removing the filter but this is not an easy task remounting and glueing the lens.

We could order 50 pc of OAK-FFC OV9282 W without the bandpass. 100 pc is to much i think, but also depends on the pricing.

Have to check that with the team. Will get back to you once I have more info.
