Hi,

Thanks for the suggestion. In any case is it possible to get those
structures ( i.e. single side over exposed and opposite side under exposed )
if the UV source is slightly tilted ? I was wondering about this since this
could be possible as our system is very old and the UV source is bit
loosened up.

Any further suggestions would be highly appreciated.

Thanks in advance.
