5.4.1 Absorbance Optics MTP
A fiber bundle guides the light from the excitation monochromator system to the
absorbance MTP optics.
The absorbance optics consists of a pair of lenses focusing the light beam into
the well of the microplate.
The spot size of the absorbance light beam is 0.7 mm in diameter.
5.4.2 Absorbance Detection MTP
A silicon photodiode is used for the measurement of the transmitted light. It is
sensitive to a wide range of wavelengths. The photodiode is well suited for the
light levels being encountered with absorbance measurements up to 3 OD.
Note
For absorbance measurement of nucleic acids of
small volumes (2µl) use Tecans’s NanoQuant Plate.
With this device it is possible to measure
16 different samples within one measurement.
