The camera imbedded in the digital eyepiece can shoot both pictures and videos. By simply connecting the microscope to your computer you can easily browse and organize pictures and videos. The ST-640 LCD Microscope makes studying plant and insect samples easy and fun for the whole family. Review: Unit arrived defective. LCD screen is very low end. Instructions are inadequate or non-existent. Electrical connections are terrible. While you can't expect much at this price, the unit should at least function and have a reasonable chance of continuing to function. Mine failed on both counts. Review: My new microscope arrived today. The AC adapter will not stay in on its own, so I am sending it back, and will be getting a refund and looking for a different microscope. I have, however, played with this one, and here is what you need to know about it before ordering. PRO -Built solid as a rock, and heavy. -Comes in a nice case. -You can look through it without the electronic stuff, using a traditional eyepiece, and it works nicely. -It comes with a lot of extras that I did not expect to get, like slides of shrimp eggs and stuff. -It runs on AC adaptor or battery power. The battery power is much dimmer. -The LCD screen is an actual camera that does video. -You can take snapshots to an SD card and there is a female mini-USB jack also. CON -Comes with no instructions about the extras. (Do you think there could be anything dangerous about the little plastic boxes that read "hatchery" and have pictures of various bacteria(?) on each compartment..?) -Comes with no warnings about potential hazards. (I accidentally looked in after turning it on but without the eyepiece, ouch. Now I can't see out of that eye very well.) -Has only one focus knob; it seems like it should have both a fine and coarse, because it is very hard to get it just right. It will focus only on part of the screen and the rest of the screen will be out of focus. -The plug will not stay in on its own and I have been holding it in. (Presumably this is because I received a defective product.) -Very big problem: the LCD screen doesn't stay on for more than about 1 minute. Bear in mind I'm holding the plug in with one hand and with the other trying to get the thing in focus. If I can hold the plug still for about 60 seconds, the screen finally will suddenly black out and say GOODBYE! and shut off. I am not making this up; this really does happen. Conclusion: This is not the microscope I want, and I'd hesitate to recommend it to anyone since there are many others in the same price range. ## Features - LCD Module with 3.5" LCD Screen, photo and video capturing capabilities, 8x zoom - 10x, 16x Wide Field Eyepiece. 4x, 10x, 40x Objectives. - 3200X maximum magnification - 2 LED illumination light sources for brighter, longer and energy-saving usage. - Save video and photos to your computer! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0032VHE0S | | Item model number | ST-640 | | Manufacturer | iOptron | | Product Dimensions | 43.18 x 20.32 x 30.48 cm; 3.63 kg | ## Product Details - **Colour:** grey - **Light source type:** LED - **Material:** PE_(Polyethylene) - **Max. magnification:** 3200 x - **Real angle view:** 45 Degrees ## Images ![ST-640 Digital Microscope with LCD Screen - Image 1](https://m.media-amazon.com/images/I/616rnUsDWbL.jpg) ## Customer Reviews ### ⭐⭐ Review *by R***K on 12 June 2016* Unit arrived defective.
