Ophir Photonics Group’s patented LD8900 goniometric radiometers perform holographic materials measurement and can make X-Y and 3-D measurements without moving either the detector or the source. This allows the far-field profilers to characterize and confirm the divergence of light passing through holographic materials, such as those used for computer display screens, smartphones and instrument panels. The 3-D capability makes it possible to measure radially symmetrical divergences and angularly different types, addressing a wide range of finished materials. Measuring diffusion materials requires testing the consistency of divergence angles across large sheets. The LD8900 line of goniometric radiometers provides full 3-D measurements of the far-field pattern in <2 min, with better resolution than that produced by a CCD camera, according to the company.
