Measuring methods for laser optics
LASEROPTIK has nearly 40 years of experience with high quality coatings. During these years we collected valuable knowledge about the properties of our optics from the best laboratories we could find: the experiences and feedbacks of our customers.
Additionally, we developed new coating techniques, measurement devices and improved coating materials in co-operation with research partners like Laser Zentrum Hannover e.V. (LZH), Fraunhofer Institute for Applied Optics and Precision Engineering (IOF) in Jena or Institut für Nanophotonik Göttingen e.V. (IFNANO, formerly LLG).
To guarantee stable high quality of our optics LASEROPTIK owns a wide range of measuring equipment:
Zeiss differential interference contrast microscope
Keyence flexible microscope
Zygo NewView 9000
Thin film stress
For many applications it is important to know exactly the thin film stress, respectively to compensate for the bending of the optics due to this stress. LASEROPTIK uses an in-situ stress measurement system and interferometric measurements for the quantification of the induced stress.
OptiSpheric 1000 AF
Zygo Verifire MST
Interferometer for smaller optics
Custom-built white-light interferometer
Cavity ring-down setup
Climate chamber and abrasion-test-set
Forward and backward scattering can be detected in the wavelength range from 190–800 nm by a custom-made measuring device based on a Coblentz sphere. We also offer external qualifications at the IOF or LZH.
To produce high power optics you have to consider the different mechanisms of laser induced damages and the influences of the substrates and coating materials. Therefore we would like to provide some background information on topic Laser Induced Damage Threshold (LIDT).
Customized product qualification
We develop and offer customized solutions for the verification of product specifications and further demands.
