A close look at microscopes
Microscopes allow us to examine the smallest particles at high magnification. They have become indispensable in medicine, biology and materials research.
The fundamental components of a microscope consist of at least two lens systems, located in the objective and the eyepiece. The objective, which is located opposite the object to be examined, has a short focal length and is responsible for the first magnification. The eyepiece, which leads to the eye, works like a magnifying glass by enlarging the generated intermediate image.
There is also an object holder, usually a glass plate, and a light source. A reflected-light microscope is used for opaque objects, while a transmitted-light microscope is used for translucent objects, with the illumination usually being implemented using a mirror.
There are various common microscope types. They can be distinguished, for example, by the type of lighting, construction and type. In addition to traditional microscopes, USB microscopes are increasingly used, which allow the generated magnification of the examined object to be easily and efficiently transmitted to a computer monitor via USB. The image can be further processed on the PC and passed on, for example to team members' computers or to smartphones.
Unique features of USB microscopes
When simply looking at an object is not enough, digital microscopes come into play. Thanks to their USB interface, digital microscopes can transmit the enlarged representation of the examination object to the computer via USB connection.
So you can not only view the image through the eyepiece, but also in high resolution on the screen of your PC or other devices with a USB port.
Photoelectric effects similar to those used in digital cameras are used for enlargement. Not only can you see the image on the display, but you can also record videos and view them on the big screen, which is very useful, for example, when viewing living subjects.
The microscopes receive the required operating voltage via a USB cable; the image transfer from the microscope to the computer is usually via USB 2.0 or now also via USB 3.
The latest variants can be connected to a smartphone or tablet via a WiFi adapter.
Buying a USB Microscope - Resolution, Magnification, LEDs, and Other Buying Criteria
Our online shop offers a wide range of USB microscopes for both private and professional use. When purchasing, you should pay attention to various factors, such as pixel resolution, video resolution and digital magnification. There are also useful additional features that might be relevant when making a choice, such as lighting for experiments or observations in dark rooms, or built-in measurement functions. Here is a brief overview of the most important purchase criteria for USB microscopes:
Magnification: 20x, 200x or 900x - this information tells you about the maximum magnification of the examination object that the microscope can achieve.
Resolution: Whether in the three-digit pixel range or megapixel range - this value indicates the number of pixels and thus the possible resolution.
Resolution (video): In our online shop you will find models with different video resolutions. You can choose between 640 x 480, 1280 x 1024, 1600 x 1200 and 2592 x 1944 pixels. The more detailed, the larger the resulting video files will be. This also increases the demands on the devices on which you want to edit the video files.
Special features: An integrated LED lighting enables optimal microscopy even in poor light conditions. Whether in a darkened room or on the go - built-in LED lights provide sufficient light to examine the material composition, surface and structure of the objects to be examined. A measurement function can prove useful in everyday work and helps to precisely analyze the examination object. For comfortable use, USB microscopes should have a robust housing and be easy to use.
Dino-Lite USB microscope cameras include DinoCapture 2.0, the powerful yet easy-to-use microscope imaging software for Windows.
DinoCapture is professional microscope imaging software designed for users of all levels. It includes basic functions such as image display and capture, measurement with calibration, through to advanced features such as geotags and edge detection.
*Some features are only available with compatible microscopes.
Practical tip: How to use a USB microscope
Before starting your experiment, you should make sure that the object to be analyzed is positioned stably and securely on a surface. The digital microscope should be positioned close enough to the object to be examined to provide a clear image. It is advisable to start with a low magnification and then gradually use a higher magnification to gradually achieve the optimal view. A stable microscope stand is also of great importance for high-quality recordings.
Frequently asked questions about USB microscopes
How should you transport a USB digital microscope?
Ideally, use an appropriate carrying case, which is often included with the purchase of a new USB microscope. You can also carry the digital microscope in another bag, but you should make sure that it is adequately padded. You can also protect the device from dirt and strong temperature changes with cloths or foils.
Which interfaces do digital microscopes have and which operating systems are compatible?
It depends on the specific model. In many cases they support the standard interfaces USB 2.0 and/or USB 3.0. Some models additionally offer the possibility of working with SD cards to store recordings, easy to carry and view on compatible devices. When it comes to operating system compatibility, you should check which systems the microscope can work with before you buy it. Usually, computers running latest Windows versions or Mac OS are easily compatible.
Are microscope cameras suitable for professional use?
Yes, high-quality microscopes have high-resolution cameras, so you can rely on the camera to provide the required quality images. High-quality digital microscopes are used in many industries and research areas today.
What good are USB microscopes?
USB microscopes offer many advantages, including portability, the ability to digitize and record, and the ease of image editing and sharing. Often less expensive than traditional microscopes, they are still functional. However, there are also some challenges. For example, image quality may not be comparable to that of a high quality traditional microscope and quality of processing may vary. Before purchasing, it is important to check reviews and specifications to ensure the USB microscope is suitable for its intended use.
