Summit OCS-KK2-1.3 - 1.3MP - Digital Microscope Eyepiece Camera for Kids Microscopes

Works good on my windows 7 system. The program that comes with it could be better.

The "1.3MP" in the model number OCS-KK2-1.3 - 1.3MP would make you to believe the camera has 1.3 megapixel resolution (which is 1280x1024). Be aware that this is not the case, the camera displays max image 640x480 pixels, which is just 0.3 MP. Calibration and many other software features do not work. Apparently this software is universal for all kines of cameras this company makes, but if used with cheapest cameras like this one, many features hare disables even though they got nothing to do with the camera itself. For instance you cannot change rulers/ units, software ignores your settings. I select distance in mm but it still shows measured distances in pixels.Also be aware that if you use it as an eye piece for the microscope, you will see on the screen about 50% of the area you'd see with your own eye, or 70% in any linear dimension (4mm fits into visible field of view optically, but only 3mm fits and displayed on the screen). The camera body is plastic. Standard microscope eye piece diameter of the section that is inserted into the optic tube is 23.2mm. This camera for some reason has this section made as cone - 23.2mm only at the base and reduced toward the inserting end to 22.8mm. This makes it very loose and wobble once inserted. So you cannot make it tight fit, the stiffness of the USB cable will make it rotate so you have to use some kind of tape to prevent it from moving. In live video refresh rate is just 2.5 frames per second, the supplied software does not have any options to change that..Overall this is only so-so camera. You do see the image on the screen (lower res., see above), but that's about it. I guess OK for kids to look at bugs and such, but not any serious work requiring measurements or capture live video. I bought this to use for electronics and PCB inspection under my microscope and find myself just displaying picture full screen, capture it into clipboard using PrtScn key on keyboard and pasting in MS PaintBrush. $59 is not a lot of money, but hardly worth it. You can likely find better cameras for that amount. Any modern USB webcam will have better resolution and live stream parameters, unfortunately they are just not meant/made to be insertedable into a microscope as an eye piece. I'm not going to return it, but if I knew what I actually how now after getting it, I would not buy this camera.
