SIENA NIR compact spectrometers extend affordable near infrared measurement into the 800–2100 nm range with an uncooled InGaAs sensor, making them practical for embedded sensors, portable analyzers, and industrial process control. Strong dynamic range, low stray light, and configurable wavelength options make SIENA a valuable solution for accurate NIR analysis without the size, cost, or complexity of cooled systems.

NYLIS high-resolution compact spectrometers are designed for applications that demand fine spectral detail in a small footprint. With resolution down to 0.06 nm FWHM, customizable wavelength ranges, and a 4096 pixel CMOS sensor, NYLIS is well suited for laser measurement, precision spectral analysis, and research tasks where narrow wavelength windows and exceptional compact-spectrometer resolution are the priority.
