LMK special imaging
FishEye / Hemispheric lens
The hemispheric lens (FishEye) enables the user to cover an object field at a field angle of ± 92°. Thus this lens can be used for capturing wide lighting scenarios. For example the measuring and determination of artifical indooe lighting and the afterwards assessment of the UGR analyzing the luminance distribution
For measuring and analysis of an angular depending luminance distribution of very small objects, for example determining the angular spread of display contrasts, a conoscopic lens (hypercentric lens) is offered. Thus luminances for many viewing angles ± 60° (circular) can be recorded in one image.
For the evaluation of luminance images captured with the conoscopic lens a LMK LabSoft AddOn is available.
With this the allocation of luminances and derived measuring values to angular coordinates of the lens or transformed spherical coordinates is easily possible.
For small object fields or tasks that does need a high magnifying a set of Macroscopic lenses offering various small measuring fields at certain measuring distances are available.
Using a modular lens construction system,TechnoTeam is able to build customized Macroscopic lenses according to customers needs.
