InGaAs Array

Product catalog summary

Introduction
The IGA-3000 Array Detectors by Jobin Yvon are designed for advanced applications in the NIR region, particularly in the semiconductor and telecommunications industries. These detectors are optimized for spectroscopic measurements, offering high sensitivity and low noise performance.

Features and Benefits
The IGA-3000 series features spectroscopic-grade InGaAs linear arrays with pixel sizes of 25 x 500 microns or 50 x 500 microns. Key benefits include:

High sensitivity and dynamic range
Excellent signal-to-noise performance
Stability for NIR applications
Multiplexing advantage without optical chopper
Quantum efficiency up to 85%

These detectors are suitable for applications such as NIR Raman spectroscopy, photoluminescence measurements, plasma diagnostics, and more.

Technical Specifications
The detectors cover a wavelength range of 800 – 1700 nm and offer pixel formats of 256x1 or 512x1. They provide cooling options of 2-stage TE or LN2, with a full well capacity of up to 130,000,000 e- in HiD mode. The detectors are controlled via a 16-bit controller and offer two acquisition modes: HiS (High Sensitivity) and HiD (High Dynamic Range).

Noise Management
The document details the noise sources affecting InGaAs arrays, including fixed pattern noise, read noise, and dark signal. Techniques such as thermoelectric or liquid nitrogen cooling can reduce noise, and dark acquisition can help eliminate fixed pattern response.

Conclusion
The IGA-3000 Array Detectors are versatile and compatible with most spectrographs, offering high performance for demanding spectroscopic applications. They are fully automated with SpectraMax software or customizable with LabVIEW.

Catalog excerpts

The new IGA-3000 series detectors feature spectroscopic-grade InGaAs (Indium-Galium-Arsenide) linear arrays with 25 x 500 micron or 50 x 500 micron pixel elements. IGA-3000 array detectors offer extremely high sensitivity, dynamic range, signal-to-noise performance and stability for NIR applications. They provide a tremendous multiplexing advantage over single channel NIR detectors, without the need for an optical chopper . The small pixels and a maximum of 85% quantum efficiency make them ideal for spectroscopic analysis: the signal produced from the spectrograph is detected without loss of the spectral information. IGA-3000 detectors are ideal for many demanding, low light level, multi-channel spectroscopic applications including: Large choice of formats Օ 50 or 25 micron pixel widths > NIR Raman spectroscopy High sensitivity and Ultra Low noise Photoluminescence measurements > Օ Two acquisition modes: HiS Plasma diagnostics An array for your requirement Emission spectroscopy Characterization of NIR laser diodes, optical filters and light sources Օ Choice for the best spectroscopic results Provides the best Signal/Noise results Fiber Optics Transmission measurements in the telecommunications industry These versatile array detectors are available in liquid nitrogen (LN > (High Sensitivity) and HiD > (High Dynamic Range) Օ Low noise or High speed operation TE or LN > 2 cooling option Օ Optimized to match applications > 2 ) and compact thermo-electrically cooled (TE) packages and are completely controlled by our compact IEEE488 based controller.
