Product catalog summary

Introduction
The 2D-OMA V:320 from Princeton Instruments/Acton is a pioneering scientific-grade 2D InGaAs camera designed for low-light infrared (IR) imaging applications. It features a 320 x 256 format focal plane array with 30-µm x 30-µm pixels, cryogenically cooled to -100°C to minimize dark noise.

Specifications

Detector: 320 x 256 InGaAs array, ideal for NIR imaging.
Pixel Size: 30 x 30-µm for good spatial resolution.
Response Range: 0.8 to 1.7 µm with >80% peak quantum efficiency.
Cooling: Cryogenic cooling to reduce dark noise and allow extended integration times.
Frame Rate: 53 frames per second with 5 MHz readout.
Interface: C-mount or F-mount for lens compatibility; PCI interface for fast data transfer.

Features and Benefits

Low Dark Current: Extended integration times and reduced background noise.
Software Control: High and low gain modes for sensitivity or dynamic range.
Data Corrections: On-line flat field and background correction.
High Throughput: Single sapphire window in the optical path.

Applications
Infrared imaging is advantageous over traditional UV-VIS imaging due to its ability to penetrate materials that absorb visible light. It is used in applications such as nanotube fluorescence, emission, absorption, non-destructive testing, and singlet oxygen detection.

Technical Insights

InGaAs Technology: Ideal for NIR detection due to low photon energy requirements and high quantum efficiency.
Dark Current Management: Cooling is essential to reduce dark current and improve detector performance.
Data Corrections: Fixed pattern noise is managed through cooling and data correction techniques.

Conclusion
NIR imaging offers significant advantages for studying biological and chemical phenomena, making it a valuable tool for researchers worldwide.
