General
Terms and Conditions
Alluna Optics aims to offer
highest quality and best possible processing of your orders. For
every order the following General Terms and Conditions shall apply:
Warranty
We guarantee a surface precision
of 1/30 wave RMS at 632nm for all our parabolic mirrors.
For all of our Ritchey Chretien
optical systems / full sets we guarantee 1/25 wave RMS at 632nm for the
overall system.
All optics and system are
interferometrically calibrated to the best of our knowledge and certified.
In the case of any optical problem we shall re-engineer or replace the
optics, provided that glass and coating is not damaged.
Any further liability shall
be expressly excluded without consideration of the legal nature of the
claim asserted.
Our mirrors are usually
free of any scratches. In the event, that there are few scratches or sleeks
on the coated surface, they do not represent in any case a derogation of
the optical performance and cannot be the reason for any complaint.
Any depression/pit within the range of micrometers that could be caused
through polishing and coating do not represent a derogation of the optical
performance and cannot be the reason for any complaint.
Guarantee
We issue a 24 months guarantee
for all of our optics and mechanic/electrical parts. Any damages
that occurred due to external hazard such as acids, leaches or impacts
of pressure shall not be covered by this guarantee. Furthermore,
all damages occurred by improper handling of the coated surfaces. Any further
liability such as costs due to disassembly or down times shall be
excluded without consideration of the legal nature of the claim asserted.
