Upgrades & Accessories
The wavefront instruments are characterized by a flexible design which allows for the adaption of the instruments to specific demands of an application. With the help of the following accessories and upgrades the function of the WaveMaster® systems are extended.
Illumination
Light sources with different wavelengths as well as numerical apertures are available. Switching between numerical apertures is simplified due to kinematic mounts.
Telescopes
For maximum utilization of the sensor dynamic range and thus the lateral resolution a set of telescopes is available.
Depending on sample diameter and wavefront sensor dimensions the optimum magnification has to be selected. The kinematic mount allows for easy exchange of the telescopes.
