Product Description

The Plugable USB2-Micro-250X USB microscope provides up to 250x magnification and can be used on computers running Windows, Mac OS X, Linux, or Android simply by plugging it into a spare USB 2.0 port and it requires no external power. It operates like a standard webcam and can be used with the default webcam software included in your computer’s operating system.

Setup and Drivers

Since our microscope uses a standard webcam chipset, it will automatically install default webcam drivers when plugged in to a computer. It can be used with any webcam app, such as:

Camera App for Windows 8.1 / 10
Photobooth for OSX
VLC Media Player

For Windows
We have custom Windows (XP SP3 and later) software designed specifically to work with the microscope. The download for this can be found below:

For Mac OS X / macOS
We also have custom Mac OS X / macOS (10.5 and later) software designed specifically to work with the microscope. The download for this can be found below:

Please note that this software package hasn’t been signed with a Developer ID, and will need to be added to Gatekeeper’s exception list prior to usage. More information on Gatekeeper and how to bypass it can be found here (specifically look under the “How to open an app from a unidentified developer and exempt it from Gatekeeper” section):

For Chrome OS
Works with the default Camera app that comes with Chrome. Some Chrome machines with built-in cameras may need to have the device pointer changed. This can be done by going to Settings > Advanced Settings > Privacy > Content Settings > Camera, and change the device in the dropdown to “USB2.0 Camera”

For Linux
Raspberry Pi: Working with the current version of Raspbian Jessie.
We have tested our Microscope with Linux utilizing GTK+ UVC Viewer by using the following terminal commands:

“sudo apt-get install guvcview”

For Android
Using the microscope on an Android device requires an OTG cable. We recommend the app CameraFi, available at:

Please note that Android support is on a case-by-case basis. Device manufacturers must have support for USB Video Class devices built in or this will not work.

For iOS
iOS is not supported. iOS hosts specifically do not work with standard external USB Video Class devices.

Frequently Asked Questions

Q: How do I magnify an object?
A: The level of magnification is controlled by a combination of the distance to the object and the focus point set by the grey focus wheel. The closer the object, the higher the magnification possible.

Q: I can’t get my microscope to zoom past a very low magnification, how do i get to 250x?
A: At the closest distance with the clear shield touching the object, there are two possible magnifications. The first is at around 50x, but if you continue to rotate the focus wheel, the image will get blurry, then sharp again at a much higher magnification.

Q: How do I dim the LED lights?
A: The LED lights can be dimmed or turned off by rotating the grey LED light control wheel near the top of the microscope body. If you are having problems with glare, try viewing your intended object at an angle.

Q: When using the microscope, all I see is a black screen with no image. How can I fix this?
A: From the factory, the LED control is in the off position. For most indoor lighting conditions, you will need to turn the LEDs on by rotating the grey light control wheel in order to see anything.

Q: When I open Digital Viewer, why do I only see output from my other webcam?
A: The microscope must be selected in the device menu under settings. The settings menu can be opened by clicking on the grey gear icon in the upper left of the window.

Q: When I plug in the microscope, I see no image and the LEDs do not turn on. What’s wrong?
A: You must launch Digital Viewer or another webcam suite in order to use the microscope, nothing happens automatically on plug-in. The microscope’s LEDs won’t work unless the image sensor is actually being used.

Q: Why can’t I get this to work with my Android device?
A: Android support is on a case by case basis. The manufacturer of the Android device must allow USB webcams or this will not work.
