Upgrade Your Microscope to Digital

There are a number of ways to upgrade your microscope to a digital microscope. First, we need to take a look at what type of microscope head you currently have. There are three types of microscope heads that are used:
Monocular Microscope
Monocular = 1 Eyepiece
Binocular Microscope
Binocular = 2 Eyepieces
Trinocular Microscope
Trinocular = 2 Eyepieces + Camera Port

Mounting a Microscope Camera Over an Eyepiece

 

Stereo Microscope with Camera Mounted over Binocular EyetubeIf you have either a monocular or a binocular microscope head, your microscope was not manufactured with digital camera connection in mind. However, you still have a few options for converting your microscope to a digital microscope. One of the simplest methods is to mount a microscope camera over the microscope eyepiece with an Over-Eyepiece Adapter. A microscope camera has a USB connection that plugs directly into your computer. When the software is opened you can view a live image from the microscope on the computer. The software allows for image and video capture as well as making measurements. WiFi microscope cameras can also be mounted over a microscope eyepiece. A wifi microscope camera works similar to the USB camera, but can be connected to an App on a smart phone or tablet where images from the microscope can be viewed and captured. Wifi microscope cameras are commonly used in classrooms and for teaching purposes.

On the right is a microscope camera mounted over a monocular student microscope.

 

Mounting a Microscope Camera on the Trinocular Camera Port


Microscope Camera and C-Mount IllustrationThe typical connection between a camera and a trinocular microscope is called a C-Mount adapter. The purpose of the C-Mount adapter is to connect the camera (with 1" c-mount threads) onto the microscope and to format the image coming from the microscope so that it will "fit" onto the camera sensor. When you look through the microscope you see a circular image, but a camera has a rectangular image, so the image you see on the camera is cut out from your circular microscope image. When using a c-mount adapter, the camera / adapter configuration looks like the image shown at left. This article explains how to find the correct c-mount adapter for your trinocular microscope.


 

Microscope C-Mount Adapters

If you have a trinocular microscope head, the microscope should have been manufactured to accept a C-Mount adapter and a microscope digital camera. Please note that C-Mount adapters are not universal and are designed for a specific brand and model of microscope. If you are unable to locate a c-mount adapter for your specific brand of microscope, you may be able to use this generic focusing C-Mount adapter. Below are some images of common types of C-Mount adapters for various microscopes. You can learn more about microscope c-mount adapters here.

Once you connect your C-Mount adapter to the trinocular port of your microscope, you are then ready to connect a microscope digital camera, WiFi wireless microscope camera, or a tablet camera to convert your microscope to a digital microscope. Below are some images of cameras and tablets connected using the C-Mount adapter on the trinocular port of the microscope.

Connecting a Digital SLR Camera to your Microscope

Microscope SLR Camera AdapterThere are two types of digital SLR cameras adapters that will connect to a microscope including standard digital SLR camera adapters and mirrorless digital SLR camera adapters. These cameras may have APS-C sensors or full frame sensors.

The microscope adapters for SLR digital cameras will connect to the microscope in one of three ways:

  1. Through a 23mm ID eyetube or trinocular tube.
  2. Through a 30mm ID eyetube or trinocular tube.
  3. Directly on  a 1x c-mount adapter.

The microscope digital SLR adapter has a lens built into it that will match up with 10x eyepiece lenses. Using a digital SLR camera for microscopy image capture will produce the highest quality images of all the digital microscopy options. If you wish to capture microscopy images for publication, using a digital SLR camera is  the recommended digital format since it will result in the highest quality images.
