LMK mobile air

digital reflex camera for luminance photography

The application of high-quality digital cameras in the LMK-system allows an easy and fast capture of luminance images. For evaluating the images, the complete functionality of the LMK LabSoft software can also be utilized.

LMK mobile control (iOS app)

Use the LMK mobile control app for a save and comfortable control of your LMK mobile air. Thus incorrect and faulty measuring results are almost impossible.

If you are already using an iOS-device (iPad is recommended) you can directly download the app from the AppStore and start working immediatly.
