SID4 Cost-Effective High Resolution Wavefront Sensor
The SID4 wavefront sensor is an entry-level yet high-resolution optical metrology instrument designed for precise wavefront measurement across the visible and near-infrared spectrum. Covering a broad 400 nm to 1100 nm wavelength range, it is well suited for laboratories and industrial environments that require reliable phase, intensity, and beam characterization without the complexity or cost of higher-end wavefront sensing platforms.
Engineered for versatility, the SID4 provides accurate optical wavefront analysis for applications in the laser industry, high-intensity laser facilities, aerospace, and defense. Its compact design and robust measurement capability make it a practical solution for laser beam diagnostics, optical alignment, adaptive optics testing, lens and optical component inspection, and general wavefront metrology. With a 5.02 x 3.75 mm² aperture, it is optimized for precise measurements of small to medium beam profiles commonly encountered in advanced photonics and optical engineering setups.
The sensor delivers a fine 27.6 µm phase spatial resolution with 182 x 136 phase and intensity sampling, enabling detailed mapping of wavefront distortions and intensity distributions. With phase resolution below 2 nm RMS and absolute accuracy of 10 nm RMS, the SID4 supports demanding optical measurement tasks where sensitivity and repeatability are essential. Its ability to capture subtle phase variations makes it especially valuable for qualifying optical systems, analyzing laser beam quality, and validating precision optical assemblies.
For dynamic measurement environments, the SID4 offers an acquisition rate of 60 fps and real-time processing up to 10 fps at full resolution when used with compatible processing software. This makes it suitable for monitoring time-dependent optical behavior, optimizing alignment procedures, and supporting live diagnostic workflows. The Gigabit Ethernet interface provides dependable data transfer and straightforward integration into laboratory benches, production test stations, and automated measurement systems.
With compact dimensions of approximately 63 x 65 x 94 mm and a lightweight body of around 400 g, the SID4 is easy to integrate into space-constrained optical setups. Its combination of high resolution, broadband visible-to-NIR operation, compact footprint, and cost-effective positioning makes it a strong choice for users seeking a reliable high-resolution wavefront sensor for laser diagnostics, optical metrology, and advanced photonics research.
