Ultra High Resolution Four-wave Interferometric Sensor

Compared to traditional microlens array Hartmann sensors, the BOJIONG Ultra High Definition Four-wave Interferometric Sensor not only offers more phase points, ensuring high resolution and the ability to reveal detailed features in measurements, but also has a wider adaptive bandwidth and a greater dynamic range, enabling it to meet a broader range of measurement needs and conditions.

The ultra-high definition resolution of the BOJIONG sensor reaches 512×512 (262,144 phase points), complemented by its wide spectral response from 400 to 1100 nanometers, ensuring high accuracy and reliability under various optical conditions. Moreover, it supports the display of 10 frames of full-resolution real-time 3D results, providing users with immediate, dynamic measurement outcomes, which significantly enhances work efficiency.
