The ACA1920-50GM represents a significant advancement in monochrome imaging technology. By combining a large 1/1.2″ sensor with modern CMOS architecture, it achieves exceptional light sensitivity while maintaining high frame rates. The absence of a color filter array allows each pixel to capture maximum light, resulting in superior signal-to-noise ratio compared to color cameras.
Delving into the technical specifications, the ACA1920-50GM features a monochrome CMOS sensor with a resolution of 1920 x 1200 pixels. The large 1/1.2″ format provides approximately 10.67 x 8 mm of imaging area, significantly larger than traditional industrial camera sensors, resulting in better light collection and improved dynamic range.

The monochrome configuration eliminates the need for demosaicing algorithms, resulting in truer representation of edges and finer details. This is particularly valuable for metrology applications where sub-pixel accuracy is required. The global shutter operation at 50 fps ensures distortion-free imaging of moving objects, essential for high-speed inspection lines.
When compared to Hikrobot’s monochrome cameras with similar sensor sizes, the ACA1920-50GM consistently demonstrates better linearity and lower noise characteristics. Basler’s rigorous factory calibration ensures minimal pixel-to-pixel variation, which translates to more accurate measurements and consistent performance across different lighting conditions.
Versus IDS monochrome offerings, the ACA1920-50GM benefits from Basler’s mature software ecosystem and industrial reliability. The camera’s rugged construction and extensive temperature operating range make it suitable for harsh industrial environments. Additionally, Basler’s comprehensive accessory portfolio ensures easy integration and long-term maintainability.
The ACA1920-50GM excels in precision measurement and inspection applications. In semiconductor and electronics manufacturing, it performs critical tasks such as die inspection, wire bond verification, and solder joint analysis. The monochrome sensor’s superior contrast resolution enables detection of minute defects that might be invisible to color cameras.
Another key application is in scientific imaging and microscopy. The large sensor format allows for wider field of view while maintaining high resolution, making it ideal for digital microscopy and automated cell analysis. The global shutter capability is essential for capturing fast-moving biological samples without motion artifacts.
For optimal performance, selecting appropriate lenses designed for 1/1.2″ sensors is crucial. Telecentric lenses are highly recommended for metrology applications as they provide constant magnification regardless of object distance, eliminating perspective errors. High-quality lenses with low distortion characteristics preserve measurement accuracy across the entire field of view.
The GigE interface supports Power over Ethernet (PoE), simplifying installation by delivering both data and power through a single cable. For reliable operation in industrial settings, use industrial-grade Ethernet switches with PoE+ capability and proper EMI shielding. This ensures stable camera operation even in electrically noisy environments.
The ACA1920-50GM represents the optimal balance between performance, precision, and practicality in industrial imaging. Its technical specifications are carefully selected to address the most demanding measurement and inspection challenges while maintaining Basler’s reputation for reliability and industrial robustness.
