商品描述

Explore the world of detail around you.

Features

The Plugable USB2-MICRO-250X USB microscope provides up to 250x magnification. The microscope is powered via USB bus power alone (500mA), so no extra power adapter is required. Operates like a standard webcam and can be used with the default webcam software included in your computer's operating system (note that some versions of Windows do not include webcam software by default, although many third-party applications are available for download).

Compatibility

Can be used on most computers and tablets supporting USB webcams, including Windows, Mac OS X, Linux, and Android simply by plugging it into a spare USB 2.0 port (OTG cable and app required for Android tablets). Native OSX support using PhotoBooth in 10.5 or above, third party support in older versions.

No iOS Support.

特点

可插入的 USB2-MICRO-250X USB 显微镜提供高达 250 倍的放大。 显微镜通过单独的 USB 总线电源(500 毫安)供电,因此无需额外的电源适配器。 操作像标准网络摄像头一样,可以与您的计算机操作系统中包含的默认网络摄像头软件一起使用(请注意,某些版本的 Windows 默认不包括网络摄像头软件,尽管有许多*三方应用程序可供下载)。

兼容性

只需将其插入备用 USB 2.0 端口(Android 平板电脑需要 OTG 电缆和应用程序)即可用于大多数支持 USB 网络摄像头的计算机和平板电脑,包括 Windows、Mac OS X、Linux 和 Android。 使用 PhotoBooth 10.5 或更高版本的本机 OSX 支持,较旧版本的*三方支持。

不支持 iOS 系统。

Not a microscope. This is a macro camera. To "zoom" you move the camera closer to the object you want to look at. It is capable of focusing on objects closer than a regular camera.

I've been measuring to see how much video detail I can get.

Optical:
very shallow depth field (maybe less than 0.1mm, definitely less than 0.5mm)
about 1.2mm field of view at closest "zoom"

Photos:
1600x1200 resolution, detail is about 25000 pixels per inch (about 10000 pixels per cm)

Video:
640x480 resolution at 8 frames per second, detail is about 10000 pixels per inch (about 4000 pixels per cm)

How small can it see?
I get about 1 micron per pixel for photos and about 2.5 microns per pixel for video.
If you want to look at something 50x50 microns in size, it will be 50x50 pixels of a 1600x1200 image, or a 20x20 pixels of a 640x480 video.
Since you have to find the object in video in order to take a photo, video becomes a size bottle neck.
How many pixels you need to identify features of what you are looking at will depend on you are trying to look at.

Note: there are two spots an object can be focused at. A near focus and a far focus. One looks bigger (more zoomed) than the other.
The maximum ratios I achieved: 29x (video, far), 74x (image, far), 112x (video, near), 280x (image, near) These are image scale ratios, and independent of monitor size!

Yes you could say my monitor is twice as big as yours, so that's 58x instead of 29x (like the manufacturer does), but no, you don't get any more information than what the camera gets.

As far as I know, you can only take photos in 1600x1200 with the official software, but I hope I'm wrong.

Pictures are:
1) calipers set to 0.01mm (at 640x480)
2) calipers set to 0.99mm (at 640x480)
3) a 100 pixel per inch LED screen (at 1600x1200).

In my search for an inexpensive, entry level digital USB microscope, I found thousands for sale on Amazon. I read many reviews and finally decided to give the Plugable Digital Microscope a try. Here's what I found....

At the $35 price point, I certainly wasn't expecting "Dino-Lite" quality or performance, but I must say that I was not disappointed. The Plugable is all plastic, but appears to be reasonably well made. It was easy to setup and get the software installed. The drivers and software are not included, but there is a link to them in the included "quick start" guide. I prefer to download software and drivers to get the most recent versions.
Once the software is installed and the microscope is assembled on the stand, just plug in the USB connection and you're ready to go.
The software is easy to use and appears to provide just about everything you need to make the most of the microscope. You can take photos or videos. There is a button on the camera for photos, but you can also click on the software button to take a picture. Since the microscope is so sensitive and can be easily moved out of position, I found it much more beneficial to take photos by clicking the button in the software.

Fact vs fiction???

The specs state that the microscope will provide 10x to 250x magnification. I didn't see any way to vary the magnification so I contacted customer service. They told me that the magnification depends on the distance the microscope is from the object in conjunction with the focus ring. It's somewhat confusing and takes getting used to, but you will get "interesting" results. In reality, there is no way to even come close to guessing what magnification you're at.

I have included some photos of a quarter at various "magnifications". As I said, it's just a matter of moving the microscope closer to the quarter and focusing accordingly. If you place the microscope right on the object and continuing turning the focus ring towards the "+", you will get two focus points, the later one being the highest magnification possible. Hopefully, the photos will demonstrate what I'm talking about.

Overall, if you just want to have some fun and you're not doing serious research or lab work, this is worth a try. It won't break the bank and it's fun for "kids" of all ages. I'm 63, retired and always looking for new "toys".

I did have to contact customer service regarding a minor issue I was having with the software. Sam, the customer service rep was very patient and knowledgeable and stayed with me until he reached a satisfactory resolution. His customer service made this purchase well worth the very reasonable price!

I initially wasn't all that impressed with the scope as the lack of an actual, printed manual makes most of the controls a bit hidden. A bit of playing around and perusing the FAQ revealed most of what I needed, but the lack of an actual manual is gonna cost a star as that effort really should have been given.

I was a bit nervous about the quality of materials at purchase, but I was pleasantly surprised. The suction cup is strong enough to resist the strength of an adult male when engaged yet releases easily when the clamp is released. The arm is strong as well, comparable to that of a good-quality desk lamp. Assembly is intuitive enough, but again lacks any real instructions on how to do so.

The controls are divided between the actual device and the desktop application. Focus and zoom are tied together on the device, so only two magnifications are possible. This removes a lot of the potential control and fine-tuning. Unless you manually re-adjust the resolution under Settings, the default is 0.3MP instead of the quality 2MP. Speaking of the Settings menu, this is also where other controls such as contrast, brightness, saturation, and hue are hidden. Contrast/brightness are basically required as dark objects tend to "black-blob" and lose detail on the digital side. Magnification is done with the focus knob (going from in-focus through a lot of fuzz until it's back in-focus at higher resolution). For those unused to microscopy, the depth of focus is expectedly low - so you will need to focus in and out for anything larger-scale.

All in all, the capabilities are really quite remarkable for only $35. Images produced are quite nice, and functionality isn't all that far behind a non-digital $700-1000 [[ASIN:B00BWXQG5W Leica Microsystems 10447197 EZ4 Stereo Microscope with 10x Eyepieces]]. Attached are some images of a 1 mm ant (a) antenna and (b) full body; an acrobat ant (c) full body and (d) thoracic spine; and a 4mm chalcid wasp (e) eye and (f) wing taken with the Plugable scope.
