SeeNano versus Light Optical Microscopes

Comparison

The following table compares the capabilities of the SeeNano Microscope with conventional top quality light microscopes:

Reflected Light - Microscopes

Conventional Light Microscope

"State of the Art"
Unchanged since the 19th century

SeeNano Microscope

Grayfield-Technology
The new standard for the 21st century

Transmitted Light - Microscopes

Conventional Light Microscope

Light reflections cause over exposure (hazy picture). Reduction of over exposure by adjustment of light field aperture which unfortunately also reduces contour sharpness.

Depth of Field:	Marginal, declines with magnification
Resolution (max):	Practically : 500nm Theoretically: 250nm
Natural Colors:	Not possible at high resolutions
Sample warmth levels:	Up to 60 °C above room temperature
Use of Living Materials:	Strictly limited due to high warmth levels. Living cells typically survive for only a few minutes.

SeeNano Microscope

No light reflection and no over exposure.
This is the basis for brilliant pictures. Iris aperture used instead of light field aperture. Extremely high contour sharpness.

Depth of Field:	Extremely high, infinitely variable, independent of magnification
Resolution (max):	Practically : 100nm Theoretically: 10nm
Natural Colors:	Unlimited up to the most extreme resolutions
Sample warmth levels:	Max. 5 °C (typ. 2 °C) above room temperature
Use of Living Materials:	Limited only by natural life span of cells. Use of chambers make long-term observations possible. e.g. 2-3 weeks on nerve cells up to several months on the pathogens of the legionnaire´s disease

Stained Slides

The Grayfield microscopes do not require any form of staining or time consuming preparation. This allows the specimens to be seen in their natural state in natural colors and in high detail.

However, in order to compare the SeeNano with conventional light microscopes, the following images were made with stained slides under a top quality conventional light microscope and the SeeNano Pro. Despite the staining, it is obvious that the SeeNano can reveal considerably more details than the conventional light microscope.
