'''AZ nLOF 2020''' has also been tested. It seems to work even at 405nm, but the dose is so high (>10000) that exposure would be slower than Aligner: Maskless 02. | '''AZ nLOF 2020''' has also been tested.

'''Dehydration reducing measures used for testing AZ MiR 701:'''<br> | |||
The CDA used for the pneumatic autofocus will dehydrate the resist. To reduce this effect, the writehead is parked far away from the write area while setting up the job for at least a few minutes, before starting the exposure. | |||
