TESTING FOR OPTICAL COATINGS<br />
Melles Griot has tested several standard optical<br />
coatings to ensure spectral performance under<br />
non-laboratory environmental conditions. The<br />
following list identifies optical coatings that passed<br />
environmental testing for salt- fog and humidity.<br />
The humidity testing was done per MIL-C-14806A<br />
paragraph 4.4.6. The salt-fog test was done per<br />
MIL-C-14806 paragraph 4.4.8 and MIL-STD-810C<br />
reference 1.3, method 509.1, procedure I.<br />
Humidity testing was done at 120ºF and the relative<br />
humidity was at 95-100% for 24 hours. Salt-fog<br />
testing was done at a temperature of 95ºF, pH<br />
solution of 6.5, collection rate of 1.18 ml/hr, and<br />
specific gravity of 1.034.<br />

COATING CAPABILITIES<br />
Melles Griot uses a state-of-the-art, Eddy Company,<br />
SYS/48B ion-assisted coating chamber for our highprecision<br />
reflective and antireflection coatings.<br />
This fully automatic system produces multilayer<br />
dielectric coatings with excellent thin film quality,<br />
high damage thresholds, and low loss. In addition,<br />
the automatic coating process allows us to produce<br />
coatings with higher precision, better uniformity,<br />
and greater batch-to-batch repeatability. This benefits<br />
not only our research customers but also our OEM<br />
customers. To meet your specific needs Melles Griot<br />
can produce custom coatings in high volume or in<br />
prototype quantities. Contact your local Melles Griot<br />
sales office for more information.<br />
Our coating chamber is located in a Class-10,000<br />
clean room to ensure coatings of the highest quality.<br />
If required, we can also inspect coated optics in a<br />
clean room and then package them in special cleanroom<br />
packaging so that the parts can be shipped<br />
direct to and opened in a clean room environment.<br />
