Goniometric Radiometer measures holographic materials.

Press Release Summary:




Capable of making X-Y and 3D measurements without moving detector or source, Model LD8900 characterizes and confirms divergence of light passing through holographic materials, such as those used for computer display screens, smartphones, and instrument panels. Far-field profiler's 3D capability makes it possible to measure radially symmetrical divergences or angularly different types. Dynamic range is greater than 24 dB for Model LD8900 and greater than 36 dB for Model LD8900R.

Ophir Photonics Group's Goniometric Radiometer Measures Holographic Materials



Logan, UT - Ophir Photonics Group, the global leader in precision laser measurement equipment, today announced the application of the patented LD8900 Goniometric Radiometer to holographic materials measurement. With the LD8900's unique design, it can make X-Y and 3D measurements without moving either the detector or the source. This allows the far-field profiler 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 3D capability of the LD8900 makes it possible to measure both radially symmetrical divergences or angularly different types, addressing a wide range of finished materials.

"Measuring diffusion materials is a challenging application that requires testing the consistency of divergence angles across large sheets," stated Allen Cary, Sales and Marketing Manager, Ophir-Photon LLC. "The LD8900 line of goniometric radiometers provides full three-dimensional measurements of the far-field pattern in under two minutes with far better resolution than a CCD camera. Unlike other techniques, X-Y or 3D measurements can be made without having to move either the detector or the source. This makes coupling the light from the source-under-test very convenient."

The company's line of far-field profilers includes the LD8900 and LD8900R.
The LD8900 has a dynamic range of >24dB and the LD8900R has a dynamic range of >36dB, providing greater detail in the "tails" of the far-field pattern. The LDR8900R also provides real-time measurements of Mode Field Diameter (MFD) in single-mode optical fibers. The angular field of view is 144° with a resolution of 0.055°.

In addition to measuring diffusion materials, the LD8900 can be used to measure laser diodes at any stage in their manufacture, from wafer to packaged product, and to optimize gradient index (GRIN) lenses.

Pricing and Availability

The LD 8900R far-field profilers are available now. OEM pricing is available on request.
