High resolution powered VGA-InGaAs NIR Camera
Equipped with an imaging module, manufactured combining photodiode arrays with high pixel separation technology (high resolution) and the integration of logarithmic readout and ultrafine gold bump, it is one of our most reliable near-infrared cameras.
Features:
- Dynamic range
- Having a logarithmic mode and linear mode, a dynamic range of 8 digits or more can be obtained. Hardly developing halations like the case in conventional charge amplifier type infrared cameras, it is also suited for infrared transmission images with greater contrasts.
- High-res
- Due to its original pixel isolation structure, it brings high resolution while maintaining excellent isolation between pixels. And by not having a groove separation structure but a planar element one, characteristic deterioration hardly occurs.
- High speed
- USB3.0 provides a 16 bit, 60 frames/second interface for speedy transfer of large amounts of pixel data.
- Built-in Peltier cooling system
- According to the newly developed Peltier built-in type package, when cooling chip efficiently with low power, it keeps the element at low temperature and maintains high sensitivity without being influenced by environmental temperature.
- Image data accuracy
- Thanks to the DC amplification method, absolute level image data can be obtained, instead of displaying only the contrast and AC coupled type suited for the human eye like the average camera.
- Built-in image processing chip
(FPGA) - It can acquire and correct data on a pixel-by-pixel basis in real time, and high-speed advanced data processing such as absolute sensitivity correction is possible as well.
- Image data acquisition /
measurement software - We offer a Windows based viewer App.
Option: LabVIEW Application - Compatibility
- In compliance with USB3 Vision, which is becoming the norm for industrial cameras, it is possible to mix multiple cameras including a visible camera in the same hub as well.
