2048L Linescan Camera

The high-resolution Sensors Unlimited 2048L high-resolution Linescan camera offers two pixel configurations: square pixels (10 x 10 μm) designed for machine vision and tall pixels (10 x 210 μm) optimized for easy alignment with spectrometers. These cameras feature Base Camera Link® interfaces, providing flexible line rates from 100 to >76,000 per second. The 2048L models ensure high resolution, stability and reliability, making them ideal for applications such as optical coherence tomography (OCT) and industrial machine vision (MV). These cameras provide high uniformity and sensitivity across the short-wave infrared (SWIR) wavelengths from 0.98 to 1.65 μm. Their simultaneous acquisition capability across all pixels ensures superior repeatability and long operating life, meeting the stringent requirements of both medical and industrial MV applications.
