There is a lot of difference (orders of magnitude) between 'a bright lamp' and the sun! What happens if you use a lens to focus the sun on a piece of paper? I would expect the same thing to happen to a sensor element with the sun's image focused on it.HermannSW wrote: ↑Sun Feb 03, 2019 2:58 pmI don't know why the sensor should break.
I once did record directly into bright lamp without issues. Because of 600fps framerate the shutter time was not high though:

I used mich brighter Ikea 1000lm lamp than the lamp for above mentioned video.There is a lot of difference (orders of magnitude) between 'a bright lamp' and the sun!
If the camera is focused on the far distance - and I got the impression that the OP's camera probably would be - the image of the sun would be in focus as it tracked across the sensor, and (since it is of finite width) each element in its path would be exposed to the image for a significant length of time. Don't forget that the concept of 'shutter speed' for the Pi's camera is just that - a concept. The camera has no shutter (or iris diaphragm) in the normal sense, so that light from what it is 'looking at' is continuously impinging on the sensor.HermannSW wrote: ↑Mon Feb 04, 2019 12:01 amhttps://www.raspberrypi.org/documentati ... /README.md
Sensor image area is 3.76 × 2.74 mm / 3.68 x 2.76 mm for v1 / v2 camera.
As understand there is no single point focus.
I would risk one of my 7 v1 cameras for an record directly into sun experiment, but weather in winter does not allow for that right now.
1000 lumens is about the light output of an old-fashioned 150W incandescent bulb - a long way from sunlight!I used mich brighter Ikea 1000lm lamp than the lamp for above mentioned video.There is a lot of difference (orders of magnitude) between 'a bright lamp' and the sun!
And to avoid dark recordings for very high framerate videos with Raspberry cameras (>500fps) I used 5000lm light.
You would need to expose for (at least) some minutes to start to model what the OP is envisaging, and even then I think that the spot intensity would be much lower with the artificial light..Perhaps time to record directly into 5000lm light ...
I have no cooling for 5000lm light, so can run it only for up to 20s because it gets very hot by 50W LED driver:
