New Software ELWICenter


With the new software ELWICenter from Hofbauer-Optik Mess- &Pr├╝ftechnik, optical systems such as complex lenses, lens assemblies, triplets and achromatic lenses can be easily adjusted and measured after assembly. The software includes an input mode that records the design data of the test object such as lens radii, thicknesses, distances and refractive indices of the glasses and calculates all relevant measured values ​​of the individual surfaces with the appropriate algorithms backwards on the actual deviations and issues. The result data can be presented in tabular or graphical form. Of course, as surface tilt angle (Sigma and Azimuth Phi) or as distance values ​​(lateral offset L and Azimuth Phi). A report with PDF representation is mandatory. The data can be output as a media break-proof document via a CSV file. All that is required is a rotary bearing, our ELWIMAT-AKF / ELWIMAT-VFS and an anxilliary lens.

Existing centering devices can usually be easily retrofitted. Please ask our specialists. See our new Video of a measuring procedure on achromat (3 surfaces):

We would like to organize our seminars as online webinars in the future. This is how we support you in the Corona crisis and can continue to improve our knowledge despite restrictions. In addition, in the course of environmental protection, we see the idea of ​​minimizing future travel to seminars. In addition to saving you time, this also reduces your costs: You can connect directly from your workplaceand the webinars are cheaper than full day events!

In order to be able to better adapt to the specific wishes and needs, we have prepared a survey that you can simply open with the link below and answer directly. The survey usually takes less than two minutes.


We are giving away three vouchers for an online webinar among all senders - the deadline for entries is September 30, 2020.

Thank you for your cooperation!
