A. Telcordia Qualifications
II-VI Marlows’ thermoelectric coolers for the telecommunication industry are fully compliant with Telcordia®1 GR-468-CORE Issue 2 (Sept 2004).
Qualification tests performed at II-VI Marlow are outlined in the table below. A Telcordia qualification report for II-VI Marlows’ telecommunication coolers is available upon request.
Telcordia Qualification Tests Performed by II-VI Marlow
|Category||Test||Sampling Size||Test Details|
|Mechanical Integrity||Mechanical Shock||22||Condition A (500 g, 1.0 ms), 5 times/direction|
|Vibration||22||Condition A (20 g), 20 to 2000 to 20 Hz, 4 min/cy, 4 cy/axis|
|Non-Powered Environmental Stress||High Temperature Storage||22||85°C, 2000 hours|
|Temperature Cycling||22||-40°C/+85°C, 100 cycles|
|Powered Environmental Stress||Power Cycling (On/Off)||22||Hot-side T ≥max. op. T, 5000 cycles|
During the mechanical integrity tests, a mass is attached to the top of the TEC to simulate the laser submount. II-VI Marlow also provides qualification testing to customer-specified requirements. Please review any specific needs with the Telecom team.

B. Space Qualifications
II-VI Marlow's extensive experience in providing space qualified applications to numerous US, Canadian, and European customers makes us uniquely qualified in providing highly reliable, optimized solutions.
Our experienced engineering staff has designed one to six stage TE coolers for operating environments ranging from 85°C to -110°C that perform in high vibration and mechanical shock environments. We have provided TE coolers for:
The products are used on the Hubble Space Telescope, the Space Shuttle, the International Space Station and various defense, meteorological, atmospheric and scientific satellites.
C. Thermal Cycling
II-VI Marlow developed and sells the most robust thermal cycling modules available. These modules, the XLT series, can be put through more than a million rapid cycles with less than a 10% change in ACR.
The demand for XLT modules is dominated by an application in which the modules are used to drive a thermal cycle that results in replication of DNA (e.g., for drug discovery and crime analysis), the polymerase chain reaction technique. The PCR cycle is between 55° and 95°C, while we drive our modules between 15° and 95°C at a demanding 5°C/sec.
The performance of our XLT modules in this qualification test far exceeds the actual requirements of our customers.
D. ISO 9001 Certification
II-VI Marlow has been recognized by the independent auditing firm Bureau Veritas as having met the qualifications required to obtain ISO 9001:2008 certification. Bureau Veritas - ISO 9001:2008 REGISTRAR
