Ask about focal length of webcam C905

I'm doing my master thesis with Webcam C905, and I'd like to know the sensor size and focal length of this camera. The customer service told me that the sensor size/focal length is 2mm. I want to further confirm does this mean sensor size is 2mm*2mm or this diagonal is 2mm?

Thank you!

Hi,

 

Array size (pixel size) is 1/4.5” (2.8um x 2.8um square pixels) and the focal length 50mm to infinite.

 

Thanks,
