Q1: What advantages does this camera have for fluorescence imaging (GFP/RFP/DAPI)?
This series of cameras is suitable for fluorescence imaging (GFP/RFP/DAPI). Its main advantages include:
High sensitivity: Low readout noise (as low as 1.07 e⁻) ensures high signal-to-noise capture of weak fluorescence signals.
Wide spectral compatibility: VIS028CU3.2-NC covers 400–1000 nm, compatible with everything from DAPI (~460 nm) to near-infrared fluorescent dyes.
Fast real-time preview: High frame rates ensure real-time observation of fluorescence signals and quick focusing.
Multi-platform software support: Comes with AttosView software and SDK to meet professional fluorescence imaging acquisition needs.
Q2: How to choose between VIS0321CU3.2-NC, VIS0220CU3.2-NC, and VIS028CU3.2-NC based on the application scenario?
All three cameras are microscope cameras, but they have different pixel sizes and resolutions:
The bigger the pixel, the stronger the light sensitivity. The 2.9 µm (VIS028) and 3.3 µm (VIS0321) pixels perform better in low-light conditions.
If you need to capture fine details, VIS0321CU3.2-NC (21MP, 4/3″ sensor) and VIS0220CU3.2-NC (20MP, 1″ sensor) are recommended. These two cameras have higher resolution and make it easier to see details.
If you need a wider wavelength range, VIS028CU3.2-NC is recommended, as it has a spectral range of 400–1000 nm (the other two are 400–700 nm).
Q2: What's the advantage of this camera's USB 3.2 Gen 2 interface compared to the traditional USB 3.0?
This series of cameras uses a USB 3.2 Gen 2 interface, offering an ultra-high bandwidth of 10 Gb/s, which is 2–3 times faster than traditional USB 3.0 models. This advantage is especially noticeable in high-resolution, high-frame-rate imaging scenarios—for example, the VIS0321CU3.2-NC can reach 240 fps (8 bit) in 1760×1318 ROI mode. The high bandwidth of USB 3.2 Gen 2 ensures that massive amounts of image data are transmitted in real time without any frame drops or delays.
