High S/N ratio
A 24-bit A/D converter, a low-noise electrical system, a high-intensity light source, a high-performance detector, and a high-throughput optical system all contribute to a high S/N of 35,000 : 1, enabling to perform small volume samples measurement and microscopy measurement with high sensitivity.

High resolution
The maximum resolution is 0.4 cm-1 and the vibrational spectrum of gas can be measured. In addition, the automatic aperture wheel sets the optimal aperture size according to the resolution.

High wavenumber precision
The specially controlled diode laser (VCSEL) has realized a long-life time and contributes to the downsizing of the instrument. By oscillating the laser with high precision using the XLD method, the FT/lR-4X has a wavenumber precision of 0.0005 cm-1 which is equivalent to that of a He-Ne laser.
