Why we decided for AREA Scan technology?
• similar quality can be achieved, both technologies have minor advantages
• Advantages: • Area: Extended Focus is possible • Line: Sample topography can be followed better
• Speed:
• „MIRAX” technology of 3DH @ 43x (0.23µm / pixel resolution) is similar to Hamamatsu and Leica but faster, than Aperio!
• New „FLASH” technology is already faster than all current competition!
Area vs. Line scanning in BF
Current „MIRAX” technology has similar image quality as competition. Some say it’s better, some say others are better, therefore very subjective.
New „FLASH” technology proved to be the best by very thorough testing at the 1st European Scanner Contest. 41 pathologists did the evaluation!
Bottom line: our current technology is in the same ballpark as competition and the new one is already significantly better as competition.
Image quality in Brightfield –
AREA vs. LINE scanning
Area scanning gives us
the ability to extended
depth of field
Advantages of AREA vs. LINE scanning
in brightfield
Lower N.A. is better, because the depth of field is larger
A typical histological section thickness is 3-5 µm, a smear thickness is 10-15 µm. A maximum of 0.84 µm depth of field difference between the best and worst objective doesn’t really matter!
Competitor’s argument for having low
Numerical Aperture
Numerical Aperture (NA)
Depth of Field [µm]
Roche (ex BioImagene) Olympus 0.5 (worst) 1.99
Leica (own objective) 0.65 1.68
Aperio (Olympus Plan-Apo) 0.75 1.31
Hamamatsu (Olympus Plan-Apo) 0.75 1.28
3DHISTECH (Carl Zeiss Plan-Apo) 0.8 NA (best) 1.15
• Line camera sensor needs the stage move continuously!
• CCD camera (area) sensor doesn’t need this: we can stop the stage!
• Why is this so important?
• Area sensor makes possible: • Extended Focus - FISH! • Z-Stack, perfect co-localization – FISH! • Change the filter as many time as we want • Have any exposure time we need • Live image
Advantages of AREA vs. LINE scanning
in fluorescence
• In fluorescence the amount of light is the main limitation
• Area sensor (3DHISTECH) collects much more light than TDI sensor (Aperio, Hamamatsu) because the sensor area is larger.
Imaged area / Magnification AxioCam %
Aperio 5 383 µm2 / 43x 4 %
Aperio 21 531 µm2 / 21x 14 %
Hamamatsu 13 867 µm2 / 21x and 43x 9 %
3DHISTECH old FL camera
150 135 µm2 / 31x 100 %
3DHISTECH new FL camera
270 400 µm2 / 31x 180 %
Advantages of AREA vs. LINE scanning
in fluorescence
Competition uses 200 Watt arc lamp. We tested it and it wasn’t better than the HXP-120. Light amount from the bulb is higher but light density is lower.
Light source
Aperio Metal Halide lamp
Hamamatsu Metal Halide lamp
3DHISTECH Metal Halide lamp or Solid State lamp
Bit depth (information in image)
Aperio 10 bit
Hamamatsu 8 bit
3DHISTECH 12 bit with AxioCam
16 bit with new PCO.edge camera
Advantages of AREA vs. LINE scanning
in fluorescence
Brightness Index = NA4 / Magnification2
• 3DH = 0.804 / 202
• Aperio = 0.754 / 202 • Hamamatsu = 0.754 / 202
• Leica = 0.654 / 202
Conclusion: Our objective collects 30% more light, than Aperio or Hamamatsu and 230% more light, than Leica
Advantages of AREA vs. LINE scanning
in fluorescence

Main features of Pannoramic 250 Flash
How fast is it?
On the 1st European Scanner Contest (2010) each vendor scanned
the same 35 slides total area of 42,7 cm².
P250 FLASH is 3 times faster, than SCAN 150 & at least 2 times faster than Leica, the winner in 2010
