![]() ![]() Hi thanks for the quick reply and you’ve done a brilliant job answering my questions. I think it is probably not worth waiting for your build. In the next release the optical performance will be the same, there will be improvements in robustness. The good news on upgrades is that the expensive hardware is the same - Pi, Pi Camera, lenses etc, so you would only need to print the plastic parts. The tube lenses are not so easy to get cheaply. For the high resolution optics you will need a tube lens as well as the objective lens. I have not looked at anything in the 40x range in between. The Pi lens is better than a cheap conventional 20x objective in my opinion. If you need 100x objective on a conventional microscope, then you will need the high resolution optics with 100x on the Openflexure microscope. The field of view is large, so finding what you are looking for can be easier than a conventional microscope. You will easily be able to see larger cells and larger organelles. ![]() The basic Pi camera lens is very good indeed. It manages well if I don’t make it run the desktop and connect from another computer. ![]() I use a Pi 3B+, and that is quite slow if you are using it as a standalone microscope, so that the Pi is operating the microscope and providing a desktop to a screen. Hi I have not got a complete answer to your question, but some thoughts. Thanks in advance for any help you folks can give me. by connecting it to classroom projectors.ġ - Is there any significant advantages between using the Raspberry Pi 2 vs the Raspberry Pi 4? I’m aware the 4 has significantly more performance but will a Pi 2 hamper the usage of the Openflexure software? We can source a Pi 2 for free but would need to purchase a Pi 4.Ģ - I’m terms of the image quality is the jump in image quality between the “High Resolution” configuration and the “Basic” configuration worth the jump in cost (around £40 by my estimate)? Our usage would focus on examination of pond water and various plant, animal, fungal cells and the larger organelles within them.ģ - I see there are developments on a next version of the OpenFlexure microscope is it worth holding off on printing and assembling the microscope to wait for this version to be released? We already have class sets of fairly budget microscopes that the kids can use but my thought was that the Openflexure microscope would be ideal for class demonstrations to complement the hands-on microscope work to allow for more complex microscopy to be carried out or to illustrate key features of cells etc. I’m a Biology teacher looking at building a Openflexure microscope for use in my school’s science classes, however I had a couple questions to help establish what configuration we need to prevent wasting money as schools are exactly fountains of wealth. ![]()
