Celestron is proud to introduce a revolutionary coating system
that outperforms any other coating in the commercial telescope
market. Our most popular Schmidt-Cassegrain telescopes are now
available with this high quality optical coating at an incredible
value.
Navigate through this section
to get detailed information on how XLT is designed, and how XLT measures up against our
current
StarBright coatings. We have also used this site as a resource
to provide information on our testing methods and we offer
a section detailing which models this new coating will be available
with and the cost breakdown for each model.

StarBright XLT & Our Commitment
to Quality
We strive to design and engineer products
with quality components using a state of the art manufacturing
process
that is followed
up with uncompromising quality assurance. You can see it
in the design and quality of our entire product line.
And our new StarBright
XLT coating system is no exception.
Design – We
design and test our optical coatings with the aid of thin film
design
software
in wide use throughout
the optical, semiconductor, aerospace, and telecommunications
industries. Using this software we have improved on our multi-layer
enhanced mirror coatings, shifting the peak reflectance to
the center
of the visible spectrum. We have designed a completely new multi-layer anti-reflective coating and have introduced a new low absorption, high transmission glass for our corrector lens. This unequaled combination is standard with every StarBright XLT system.
Quality Components and
Process – Our
coating process uses state-of-the-art thin film vacuum deposition
technology.
To ensure consistent optical coatings of the highest quality
the process is tightly monitored and controlled by highly trained
coating technicians. Prior to coating, each optical element
is thoroughly cleaned and inspected to ensure proper adhesion
of the films during the coating process. The materials used
in our reflective and anti-reflective coatings including Aluminum,
Hafnium Oxide, Titanium Dioxide, Silicon Dioxide, and Magnesium
Fluoride are the purest available, exceeding 99.99%.
Quality Assurance -
Our QA process is designed to prevent any optical element from
passing if it does not meet our strict
standards of optical quality. Witness plates are included in
each coating run, and are subjected to spectrophotometric analysis
to determine if the minimum acceptable transmission or reflectance
has been achieved. |
