Stereoscopic Microscopes

What is a Stereo Microscope?

Probably the most general form of an optical microscope. These systems generally provide a user with a lower magnification range than compound microscopes and have longer working distances for imaging larger, three-dimensional targets. Stereo microscopes have two eyepieces to allow for 3D observation and are useful when performing assembly or re-work.

Stereoscopic Microscope Parts and Functions

A stereoscopic binocular microscope generally consists of several components. The stage holds the sample, and light is projected down onto the sample from underneath the lenses. The objective lenses take in the image and magnify it. A focus knob is used to bring the head up and down to provide a clearer picture. The stereo head contains the ocular lenses, which are what the observer looks through to see the image.

Stereo Microscope Applications

As the most common type of optical microscope, stereoscopic microscopes can be found in a wide range of environments and applications. They are used in classrooms, laboratories, and production facilities to observe fine details of multiple types of materials. For example, stereoscopic dissecting microscopes may be used by entomologists to study insects, or by electronics repair professionals while repairing circuit boards.

When considering whether to use a compound microscope vs. a stereoscopic model, it's important to note that the latter enables 3D images. Because they split the same optical path to both eyepieces, compound microscopes only provide a 2D view, albeit at greater magnifications.

The Merit of VHX Digital Microscope as a Stereoscopic Microscope

1. Full focus - Sharp focus on the entire target

Digital microscopes achieve a large depth-of-field, allowing for accurate observation of a target with a highly uneven surface.
This type of observation helps to greatly reduce the amount of time needed for focus adjustments.

2. Flexibility - View from any angle to never miss another detail

With Variable-angle Observation capability, digital microscopes can achieve observation from multi angles freely, without having to tilt the target.

3. 2D measurements & reporting - Perform advanced measurement and analysis

With just a few clicks, perform a variety of real-time measurements—from distance, radius, and other 2D measurements to automatic area measurements—directly on the screen.
Data can be saved and accessed later for further measurement. Moreover, free communication software makes it possible for anyone to utilise the measurement functions from their own PC.

4. 3D measurement - 3D image stitching and roughness measurement

Digital microscopes can produce fully focused, 3D displays at the push of a button. The three-dimensional measurement function achieves easy observation of the surface shape of a target, and simplifies communication with others.

5. Hand held capability - Observe from all directions

VHX Series Digital Microscopes offer easy, handheld observation. By adjusting the viewing angle of the camera and lens, you will never miss a detail when observing a sample. Furthermore, the time required for inspection can be considerably reduced.

6. 4K monitor - Quickly analyse and discuss an image

Magnified images are displayed onto a large, high-resolution monitor, enabling several people to observe and discuss the images simultaneously on-site. Users can then conduct analyses more efficiently and immediately respond to customer complaints.

7. Optimal lighting - Automatic acquisition of lighting from all directions

By simply pushing the Optimise button, nine different lighting scenarios are displayed.
From there, you can quickly select the image that is ideal for observing your target.

8. Glare removal - Ring removal function suppresses glare on targets

To prevent certain parts of the image being unobservable due to glare, multiple images are acquired while changing the direction of the ring light. This makes it possible to remove unwanted glare on the surface of the target at the press of a button.
