Fitting cameras to microscopes
With such a huge choice of cameras ensuring you get the correct adaptor for your microscope is a difficult area made simple by GT Vision. Broadly speaking their are two types of cameras:
1. cameras with fitted lenses
2. cameras with no lens
If you have a camera that already has a lens that cannot easily be removed (typically a digital domestic or semi-professional camera) then you will need an adaptor that simply holds the camera in position over the eyepiece or phototube of your microscope.
This is not an ideal arrangement.
The best choice is to attach a camera that has no lens but instead has a mounting that is ready to receive a lens or microscope adaptor. These mounts are often C-mount or F-mount (although there are several others). These types of cameras are much easier to attach and the result is rather better.
Each camera and microscope also has a range of characteristics that will also influence the choice of adaptor that should be used. These include:
No. of CCDs
3 CCD cameras need 3CCD corrected optics to avaid red/blue vertical color casts over the image.
Tube Length
A crtical factor with many microscopes. Using a coupler that is not matched to the tube length of the microscope can seriouly affect the quality of image and magnification achieved
Size of the CCD chip
The size of the CCD chip in the camera will affect the size of the image displayed by the camera. Extra lenses in the adaptor allow you to match the camera’s field of view to that of the eyepieces.
For detailed advice about how to connect a camera to your microscope contact our experts HERE giving a description of your microscope and required camera.

Calculating the image size of a scanned slide
When considering using a system such as the Surveyor rapid slide scanner prospective users aften ask us questions like...”what size image will be created if I scan my entire slide slide”. the answer depends on many variables such as camera resolution, objective selected and the microscope-camera adaptor used.

Portable microscopy
For work in the field scientists need lightweight high quality optical systems, the new range of Z6 and Z16 microscopes is ideal for this task. The microscopes double up as a macroscope and you can even fit an objective for high magnification work.
