![]() But the lens does start to unscrew! The autofocus also works, although of course the focus range becomes very reduced. Twisting the lens has quite a bit of resistance at first, so the camera body needs to be supported. I don’t actually need a camera, this is just to work out whether it is possible to use the new sensor with other lenses. Surprisingly this did not immediately break the autofocus mechanism. ![]() Prepare the main body and rectangular z-axis. Grabbing the lens it will move in and out a bit, and twist a bit before coming to stops. The assembly is broken up into several steps: Test your printer. The lens is freely floating on the autofocus mechanism. The stage is capable of sub-micron-scale motion, with very small drift over time. The Camera module 3 does not come with a lens removal tool like Pi camera v2 usually does. OpenFlexure is a 3D printed flexure translation stage, developed by a group at the Bath University. It is not recognised as a camera, which may be more about drivers than about how the software talks to it. Unsurprisingly it does not work immediately on a microscope Raspbian Openflexure, which is based on an older version of the Pi operating system and a different camera software. It works on a new install of the Raspberry Pi OS, which needed updating to get the new camera driver. Having significantly more pixels than needed for the optical resolution would just bloat the image sizes. By cropping we could also use more of the useful optical image area with a nearly square crop to 3.68mm wide (width of image circle designed for the V2 camera) by 3.63mm high (limited by the height of the V3 camera), which gives nearly 7MP. With fewer, bigger, pixels than V2, and a newer sensor design one would hope that the noise is quite a bit better. You are only paying for the materials and our time. Over the past 3 years, the microscope has primarily been co-developed. If you buy a microscope or microscope kit from us you will get the exact same microscope as if you print and assemble it yourself. The OpenFlexure Microscope is a 3D-printed laboratory-grade motorised microscope. Everything OpenFlexure Industries produces is 100open source. Camera V1, also had 1.4µm pixels and gave 5MP which is still probably more than the actual optical resolution of the system. OpenFlexure Industries is committed to openness. ![]() Of course, one could just keep the same optical train and then only use the central part of the sensor. This brings bigger design questions in the optics modules, to make use of that larger sensor area might mean a longer optical train - There is a bit of a thread here. In fact it is nearly as big as the High-Q camera - smaller diagonal, but higher aspect ratio, so the long dimension is bigger on Camera Module 3 and the short dimension is bigger on High-Q camera. The pixels are bigger, and there are more pixels, so the overall sensor is almost twice as big on the specification comparison.
