Figure 30. Laser excitation from above to adjacent well/reading from 
above.  

Both excitation and emission occur from the top of the sample. Bottom 
reading is not possible with AlphaScreen in EnVision.  

Only one measurement per well is recommended because the sample is 
partially bleached by the excitation light.  

Crosstalk is a factor that must also be taken into account. There are three 
components: bleaching caused by the excitation of adjacent samples, 
afterglow from a previously excited adjacent sample and glow from an 
adjacent well at the time of measurement. A crosstalk correction wizard 
allows the amount of the crosstalk to be measured and the software uses this 
as a correction factor in the calculation of the final result.

above. Bias mirror module with a single mirror is used.
