SID4 UHR Ultra High Resolution Wavefront Sensor for Optical Metrology

The SID4 UHR Ultra High Resolution wavefront sensor is designed for demanding optics metrology applications where dense spatial sampling, precise phase measurement, and a large analysis aperture are required. Developed for live wavefront measurement across complete optical samples, this compact instrument supports advanced characterization of lenses, objectives, aspherical optics, freeform components, optical surfaces, and laser beams. Its ultra-high-resolution phase mapping makes it especially suitable for laboratories and production environments that require accurate inspection of complex optical elements.

Unlike conventional wavefront sensing approaches that may require a compromise between field coverage, sampling density, and implementation complexity, the SID4 UHR combines high-resolution measurement capability with straightforward integration. With phase and intensity sampling of 554 x 554 points and an optional 666 x 666 configuration, it provides a highly detailed wavefront map for identifying subtle optical defects, high spatial frequency errors, surface irregularities, roughness signatures, and localized aberrations. This makes it a strong choice for optical component validation, precision alignment, quality control, and research-grade metrology workflows.

The sensor operates across a broad 400 to 1100 nm wavelength range, making it compatible with many visible and near-infrared optical systems. Its 15.29 x 15.29 mm² aperture enables direct measurement over relatively large samples or expanded laser beams, reducing the need for additional relay optics in many setups. A spatial resolution of approximately 27.6 µm supports fine-scale analysis, while the phase resolution of less than 5 nm RMS provides the sensitivity needed for high-precision wavefront metrology and surface inspection.

For laser characterization, the SID4 UHR delivers precise phase and intensity information that can be used to evaluate beam quality, wavefront distortions, optical alignment, collimation, and system aberrations. Its high-performance camera and optimized signal-to-noise performance support reliable analysis in research, development, and industrial test benches. The ability to capture instantaneous measurements over a large field is valuable for fast setup verification and repeatable optical testing.

The SID4 UHR is also well suited for the characterization of advanced optical components, including microscope objectives, imaging lenses, molded optics, precision polished elements, aspheres, and freeform surfaces. In surface inspection applications, it helps detect roughness, polishing defects, high-frequency deformation, and other surface-related issues that can affect optical performance. Its combination of compact size, USB 3.1 interface, and real-time processing capability allows it to be integrated into metrology stations, automated inspection systems, optical benches, and manufacturing quality-control platforms.

With dimensions of approximately 73 x 70.5 x 93.2 mm and a weight of about 475 g, the SID4 UHR offers high-end wavefront measurement performance in a compact footprint. For users searching for an ultra-high-resolution wavefront sensor, optical metrology sensor, laser wavefront analyzer, surface inspection instrument, or high-density phase measurement device, the SID4 UHR provides a precise and versatile solution for both research and industrial optics applications.
