Libra 3405UC Global Shutter Color CMOS Camera, 5 MP, 65 fps, USB 3.0
Libra 3405UCDesign Tools
Plug-and-play 5 MP global shutter color camera for microscope workstations and slide scanning over USB 3.0.
The Libra 3405UC is a compact, USB-powered color camera with a 5 MP global shutter CMOS sensor (GMAX 3405). It connects directly to standard microscopes and PCs over USB 3.0 and reaches 65 fps at 8 bit at the full 2448 × 2048 resolution. ISP auto white balance and AI-based color correction give dependable color for H&E-stained sections and teaching, while the global shutter avoids motion artifacts during fast scanning.
Key Features
- Global shutter exposes all pixels simultaneously, avoiding motion blur and distortion during fast stage movement
- USB 3.0 plug-and-play connection; powered over USB at under 4 W
- ISP auto white balance and AI color correction for accurate color in H&E staining and teaching
- Acquisition and analysis software with real-time image stitching and depth-of-field fusion
- 3.4 µm pixels suited to optical systems below 40×, resolving fine detail in cell and tissue samples
- Three gain modes; readout noise down to 1.7 e⁻ in Sensitive mode (12 bit)
- Compact 45 × 45 × 60 mm passively cooled housing; C-mount or customized optical interface
Typical Applications
- Pathology slide scanning
- Fluorescence slide scanning
- Bright-field microscopy
- H&E-stained section imaging and teaching
- Industrial inspection
