NIR(Near Infrared) Mapping using IR Microscope

Introduction

The measurement range with an infrared (IR) microscope fitted with an MCT detector is normally 5,000 - 700cm^-1 . In order to measure spectra in the near infrared (NIR) region with an IR microscope, it is necessary to change the FTIR light source and beam splitter. Shimadzu’s new FTIR model IRPrestige-21 allows measurements in the NIR region by using the NIR kit, which includes a tungsten-iodine lamp, CaF₂ beam splitter, and InGaAs detector. Here we introduce an example of mapping in the NIR region by the transmission method, which was performed using an IR microscope and IRPrestige-21 fitted with the NIR kit.
