3.5 Optical head

The optical head measures the chemiluminescence of each microplate well. The optical head has an optical mask and an
optical mask retainer. The optical mask isolates one microplate well from the other microplate wells so that the DML 3000 can
measure only that one microplate well. The optical mask retainer maintains the position of the optical mask.

3.6 Plate carrier

When a 96-well microplate is placed in the DML 3000 for measurement, the plate carrier keeps the microplate positioned
securely against the plate mask. The spring-loaded base of the plate carrier pushes the microplate up into the plate mask for
a tight fit. Once the microplate is placed inside the plate carrier and the plate mask is closed, the springs provide a light
upward pressure to secure the microplate in place.
The A1 corner is located in the back-right location. The A1 label acts as a visual aid to help properly position the microplate.
