A video lens system can be configured in countless ways, however the core components are usually the same:
- Focus Mount
- Macro or micro C/CS mount video lens
- C/CS mount video camera
- Video monitor display
- Light source
Assembling these components together can be done in a few easy steps
- Secure the lens to the lens adapter
- Place the lens into the focus mount
- Attach the LED ring light to the bottom of the lens
- Connect power to the LED ring light, connect power to the camera, and connect the camera to the video output display (usually USB or HDMI)
Step 1. Zoom the microscope all the way in to it’s max magnification, then adjust the microscope position until there is a clear image.
Step 2. Zoom the microscope all the way out, then adjust the focus of the eyepieces until there is a clear image.
Step 3. Adjust the camera collar until there is a clear image on screen.
Now the microscope will remain in focus through the eyepieces as well as on screen, with no need to adjust the optics. To learn more visit aventools.com, or contact us at firstname.lastname@example.org
Choosing the right Digital Inspection system can be confusing. There are many different types of systems available today at price points ranging from $150 to over $10,000.
It is important to clearly establish what functions you expect the system to perform and what you hope to accomplish with the system. For example, will this be used at a desk infrequently for quick inspection or in a quality lab to take measurements or on a production line to reduce eye fatigue or for a variety of different applications.
Below are typical types of digital microscopes on the market today with typical applications.
USB Digital Microscope
Dual HDMI & USB Output Scopes
Auto Focus HDMI Systems
In addition to determining your requirements for an inspection system, it is also important to remember not all inspection systems are “one size fits all”. It is critical to work with an expert that has a diverse product offering to tailor a solution to fit your needs, whether in production, parts inspection, engineering or casual product review.
Microscopes are required across many aspects of industry for inspection purposes. Products coming off electronic, agricultural, medical and automotive production lines need to be carefully scrutinized. Passports need to be manually looked at, PCB and IC’s need to be checked for integrity. And while machine vision can automate the rapid inspection of an ever-expanding spectrum of products, the majority industrial inspection applications still rely on a visual confirmation from a real human.

There are a lot of options available when it comes to imaging systems. This is a good thing, as there is almost certainly an imaging system that will suit your individual needs. Here are some tips for finding the best system for your applications.
Select Your Lens
First, consider these four key elements:
- Field of View
- Depth of Field
- Working Distance
These will determine what sort of lens is required for your ideal imaging system. A field of view is the area that the lens can see, and depth of field is the area in focus at one time under magnification. Very small objects will require a micro lens with a higher level of magnification and lower depth of field. Larger objects will require a macro lens, which will offer a lower level of magnification and higher depth of field. Additionally, higher magnification reduces working distance while lower magnification increases working distance.
Once you’ve determined your field of view and chosen a lens, think about your overall goals. What are you viewing, and what do you want to do with it? Whatever the objective, you want the highest possible level of image resolution. At this point, it’s time to think about cameras.
Select Your Imaging Camera
Two of the most common imaging sensors found in digital cameras are CCD and CMOS. CCD stands for “charge-coupled device” and are designed to help remedy challenging lighting and color conditions. Despite low light applications or very small objects of study, the CCD sensor provides extremely precise color reproduction and highly detailed images, capturing a precise, high resolution images of moving objects. CCD cameras are ideal for examining things like cell structures, and are a popular choice among medical researchers.
CMOS stands for “complimentary metal oxide semiconductor” and is a great choice for parts inspection, clinical and industrial research, and any imaging application wherein it is critical to reduce lag time from one image to the next. Images from a CMOS camera are known for exceptional clarity, which greatly enhances the operator’s experience making measurements and annotations.
Inspection cameras come with several output options including USB and HDMI. Your choice will determine speed of frame rate and how images are viewed. Cameras with a USB 2.0 or 3.0 output both connect directly to your computer (as a result, a PC is required to view these images). Though both USB outputs function in the same manner, USB 3.0 is faster and helps to reduce lag time between images. USB cameras generally come feature rich software for image capture, annotations and measurements.
Cameras with an HDMI output connect directly to an HD monitor, eliminating the need for a computer. This saves bench top space and removes the image lag time that occurs with USB image processing. HDMI cameras generally come with an SD or USB flash drive for saving images. More advanced models come with imaging and measurement software.
Select Your Illumination
Next, think about illumination. LED ringlights are ideal for macro lenses and lower range magnifications, while Fiberoptic Illuminators (FOI) provide intensity and focus of light, and work well with micro lenses and high-range magnifications. They also save a significant amount of energy, making them better for both the environment and your budget. Backlights are generally placed underneath the object to be viewed and connected to the fiberoptic illuminator for further enhancement. A polarizer is essential for viewing shiny parts, as it helps to eliminate glare and bring out surface details.
If you are looking at highly specular or shiny surfaces and need hot spots and glare to be completely eliminated, we recommend our Diffuse Axial LED Illuminator. This, when attached to our stereo microscopes, will provide a very high level of clarity.
Lastly, choose a stand appropriate to the size and weight of your inspection system. High quality stands are made of durable material that is resistant to shaking and vibrations. Some models will have built-in mounts for attachments. Once this simple and final step is completed, you’ll have created a video inspection system tailored to your application, ready to work for you.
Choosing the right inspection system for your application can be a daunting task. For industrial applications 3 types of inspection systems are generally used. This guide describes these systems, their common applications along with pros & cons.
Stereo Zoom Microscope
The stereo zoom microscope is the most commonly used microscope in industrial applications. A stereo scope generally consists of a main objective lens, two eyepieces for viewing with a magnification range that tend to top out at 200x.
- Multiple types of precision assembly work including but not limited to soldering, medical device manufacturing, and laboratory use.
- Larger working distances allow user to work with tools (soldering iron, cutters etc.) under the microscope.
- Live 3-D view and excellent depth of field making precision assembly easier.
- Low first cost.
- Image Capture and Digital Measurements are not possible.
- Eye fatigue from constant use
- Limited Magnification Range generally up to 200x
Trinocular Stereo Zoom Microscope Inspection System
This system features a stereo zoom microscope as described above, with an additional third port to support a camera for image capturing. The camera can then be connected to a computer (USB Type Cameras) or directly to a monitor (VGA, SXGA, HDMI type cameras).
- Assembly applications that do not require constant 3-D image with large depth of field.
- Assembly applications where image capture and measurement may be necessary.
- Quality Inspection where some assembly/rework/repair may be necessary.
- 3-D View visible when working underneath the scope along with additional 2-D Screen monitor view that helps to reduce eye fatigue. No eyepieces required for this view.
- Image Capture and Measurement capabilities when paired with a USB/Digital Camera.
- Loss of 3-D Depth of Field when viewing on Monitor
- Higher first Cost then Stereo Zoom Microscope
Video Lens Inspection System
Systems consist of a single lens paired with an USB/HDMI/Analog camera attached to a monitor or computer. Systems can be built piece by piece or are pre-configured and pre-assembled like the Aven Mighty Scope or Cyclops. Magnification ranges for video inspection systems can go up to 3000x.
- Quality Inspection and Documentation
- Performing Measurement and other analysis when paired with USB Camera
- High Magnification Applications
- Light Assembly work at low magnifications
- Versatile systems that can be configured in multiple ways to provide a wide range of magnifications.
- Easy Image Capture and Analysis when paired with USB Camera
- Significantly reduces eye fatigue when used in lieu of traditional microscope.
- Priced for almost any budget
- 2-D only image that significantly reduces Depth of Field at higher magnification when compared to a traditional stereo microscope.
- When paired with USB Camera image may “lag” when moved.
When considering an inspection system that is right for you, evaluate your specific application needs, budget allocation and comfort levels. Before investing in a system it may be helpful to consult with a supplier specializing in optical instruments and professional tools, such as Aven founded in 1983.
