Coatings in the infrared spectral range – protection of sensitive surfaces

Infrared coatings protect your surfaces and are ideal for materials with specific, complex properties. We offer a wide range of infrared optical coatings in the wavelength range from λ1.5 to 20 micrometers. They are characterized by their high quality, durability and robustness, and can easily withstand even the harshest environmental conditions. They are also completely free of radioactive materials.

Jenoptik provides the following standard coatings:

• Bandpass and narrow band filters
• Dual and triple-band filters
• Edge filters (long and short-pass)
• Multifunctional filters
• with anti-reflective coatings

In addition to the standard IR coatings, we can also provide custom solutions matching your specifications. We regularly control the quality of our coatings. We also work with an independent testing and calibration laboratory to qualify our optical components. We have extensive experience of the various test methods and will select the procedure most appropriate to your application. Testing is performed on the basis of all relevant DIN, IEC, EN and MIL standards, while the coatings themselves comply with the strict requirements of the standards MIL-C-48497 and MIL-F-48616.

The following tests – or combinations thereof – are possible:

• Optical parameter inspection: interferometric testing; aspheric testing with CGHs; transmission measurement up to temperatures of 95 K; MTF measurement in temperature range from 233 K to 333 K; wiper test for front faces with DLC coatings (based on TS1888).
• Testing for climatic stability subject to changes in temperature and humidity as well as temperature shock: determination of temperature and climate boundaries; realization of thermal stress parameters.
• Shock and vibration testing
