Applications of the High-Resolution VGA-InGaAs Near-Infrared Camera NVU3VD
Dark-Field Infrared Microscopy
Combining with LED dark-field illumination enables clear transmission images of silicon with reduced surface light reflection.

Multi-Spectrum Imaging Technology
The multi-spectrum imaging system of the InGaAs Near-Infrared Camera NVU3VD captures images under different wavelength lighting conditions, allowing for precise identification of subject components. The following image shows an object illuminated with multi-color infrared LEDs and captured by the NVU3VD.
[Example]
While a liquid appears transparent in visible light, the InGaAs Near-Infrared Camera NVU3VD can capture differences in wavelengths between water and oil components, represented by shades in black and white.
Core Technologies of the High-Resolution VGA-InGaAs Near-Infrared Camera NVU3VD
Ceramic Package with Built-In Peltier Element
A compact package with a built-in electronic cooling module. Tests of the chip temperature at 5 °C and ambient temperature (25 °C) showed approximately 8 times improvement in sensitivity at 100 fW/pixel.
High Pixel Density with Internal Potential Barrier Structure
Enables high-resolution, clear images by minimizing crosstalk even with increased pixel density in the pixel array.
