Both options use white light imaging sources. For Epi-illumination the light source is lo-
cated at the top of the Amersham Imager 600 interior. For Trans-illumination the sample
is illuminated from the light source at the bottom of the instrument interior. When using
Trans-illumination, the intensity data is converted to optical density (OD values), which
provides a more quantitative result compared to Epi-illumination.
Colorimetric capture is only available with Lower tray position.
Note:
The images are by default created with automatic exposure time.
The table below describes details on accessories and tray positions for colorimetric image
