Q1 : VIS091CU/MU-NC (1.7 megapixels, 9 µm large pixels) is suitable for which applications?
The VIS091CU/MU-NC comes with a Sony IMX432 sensor, offering a resolution of 1.7 million pixels (1600×1100) and a pixel size of 9.0 µm × 9.0 µm. This model has the following application highlights:
Top low-light sensitivity: The 9 µm large pixel area can collect more photons, combined with high sensitivity of 4910 mV/(lux·s) and a peak quantum efficiency of 89% @ 610 nm, making it perform excellently in low-light conditions.
High frame rate: Up to 98.6 fps at full resolution, ideal for microscopy applications that need fast preview and real-time observation.
Wide spectral coverage: 400–1000 nm wavelength range, compatible with imaging modes from visible to near-infrared.
This model is especially suitable for fluorescence imaging, live cell dynamic observation, and detecting weak-light biological samples where sensitivity and speed are key.
Q2 : 2.74μm/3.45μm/4.5μm/9μm pixel sizes corresponding to experimental needs?
9μm (VIS091): Largest single-pixel photosensitive area, best fluorescence signal-to-noise ratio; ideal for budget-limited, low-magnification brightfield/fluorescence experiments, though resolution is a bit weak.
4.5μm (VIS047): Balanced sensitivity and resolution, a versatile model for general cells, metallography, and medium to small wafers.
3.45μm (VIS0312/VIS035): Small pixels, specialized for high-magnification oil objectives, tiny lithography, and fine sectioning, offering better detail resolution.
2.74μm (VIS0220): Smallest pixels in the series, ultra-high-resolution panoramic scanning, perfect for high-density PCBs and large-area precise pathology inspections.
Q3 : How to choose between a global shutter and a rolling shutter?
This series offers both global shutter and rolling shutter versions:
Global Shutter (VIS091, VIS047, VIS0312, VIS035, VIS0220 series): All pixels are exposed at the same time, making it great for capturing fast-moving objects and avoiding motion distortion and blur.
Rolling Shutter (VIS0326 series): Exposes line by line, which results in lower noise in low-light imaging and is suitable for static or slow-moving imaging scenarios.
