Patent ID: 6948825

Claim:
A measuring device, comprising: an illumination arrangement for illuminating an object to be measured comprising several light sources ( 18 , 20 , 22 , 24 , 26 , 28 , 30 , 32 , 34 , 36 , 60 , 62 , 64 , 66 , 68 ) going out from a support ( 16 , 70 ) as well as an optic by means of which the object can be measured or imaged, where the light sources are arranged such in the support ( 16 , 70 ), that incidence angles (α, β, γ, δ, κ) intersect the optical axis of the optic in different areas ( 48 , 50 , 52 , 54 , 56 ), wherein the optic ( 48 , 50 , 52 , 54 , 56 ) of the measuring device designed as coordinate measuring device is a zoom optic with variable working distance, that the incidence angles (α, β, γ, δ, κ) of the light sources ( 18 , 20 , 22 , 24 , 26 , 28 , 30 , 32 , 34 , 36 , 60 , 62 , 64 , 66 , 68 ) are arranged such that incidence angles of light sources intersect the optical axis ( 14 ) in each adjusted working distance regions of the optic, or that the optic has a constant working distance and the object ( 72 ) is illuminable by moving the support ( 70 ) along the optical axis ( 14 ) relatively to the optic under different angles of incident light.
