Libra 3405UM Global Shutter Mono CMOS Camera, 5 MP, 65 fps, USB 3.0
Libra 3405UMDesign Tools
USB-powered 5 MP global shutter mono camera with NIR sensitivity for multi-channel fluorescence slide scanning.
The Libra 3405UM is a compact monochrome camera with a 5 MP global shutter CMOS sensor (GMAX 3405) and a plug-and-play USB 3.0 connection. Its 350–1100 nm response, with 75% QE at 540 nm and 47% at 800 nm, suits multi-channel fluorescence and near-infrared detection. Full-resolution 2448 × 2048 images are delivered at up to 65 fps (8 bit), and the camera draws its power directly from USB.
Key Features
- Global shutter exposes all pixels simultaneously, avoiding motion blur and distortion during fast stage movement
- 350–1100 nm response with 75% QE at 540 nm and 47% at 800 nm for multi-channel and near-infrared fluorescence
- USB 3.0 plug-and-play connection; powered over USB at under 4 W
- 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 1.6 e⁻ in Sensitive mode (12 bit)
- Compact 45 × 45 × 60 mm passively cooled housing, ~162.5 g; C-mount or customized optical interface
Typical Applications
- Tissue fluorescence slide scanning
- Multi-channel fluorescence imaging
- Near-infrared detection
- Microscopy imaging
