Q1 : Differences in application scenarios for HCG/LCG/HDR gain modes?
HCG High Gain: Extremely low readout noise, suitable for weak fluorescence, trace UV spectroscopy, and low-light static samples; smaller full-well capacity, easily saturated by strong light.
LCG Low Gain: Super large full-well capacity, suppresses overexposure in UV lithography and high-power laser pixels, commonly used in bright-field industrial inspection.
HDR (only supported by UVISI091BU-NC/UVISI064BU-NC): Combines high and low gain, preserving details in both bright and weak light, specialized for samples with mixed brightness and interference fringe imaging.
Q2 : Difference between 11μm / 9.76μm / 6.5μm pixel options?
UVISI114BU-NC (11μm max pixel): Has the largest single-pixel photosensitive area, peak QE 95.3%, best for weak fluorescence, trace spectroscopy, and low-light signal-to-noise ratio; ideal for low-light research, but the downside is lower spatial resolution.
UVISI091BU-NC (9.76μm balanced pixel): Balances sensitivity and resolution, a good choice for general labs, standard fluorescence, or small industrial quality inspections on a budget.
UVISI064BU-NC (6.5μm small pixel): Ultra-high spatial resolution, perfect for lithography micro-defect detection, high-magnification microscopy, and precision pattern inspection; under the same lighting, its low-light signal-to-noise ratio is weaker than the two larger-pixel models.
Q3 : Choosing between a non-cooled BSI and a TEC-cooled camera?
Advantages of non-cooled: small size, light weight, low power consumption, no preheating needed when turned on, lower price, and portable/integration-friendly; suitable for short sequences (<60s) in offline experiments or small production lines.
Drawbacks of non-cooled: dark current increases with temperature, and weak light imaging is noisy for long sequences.
