Measurement of Large Diameter Vessels
1. Can I visualize the diameter of large vessels—greater than around 350 µm, or those having thick walls?
Yes. Generally, these measurements are limited to only the outside diameter since the light is dispersed passing through the vessel making the inside diameter difficult to detect. Our instruction manual details a method for tracking the outside diameter of large, thick-walled vessels.
When visualizing large vessels, a reduction lens is generally required between the microscope photo port and your video camera. Living Systems Instruments offers 0.5X and 0.3X C-mount reduction lenses for this purpose.
