Key advantages

Ultra-high spectral resolution

Down to 1.8 cm⁻¹ depending on model and slit configuration — confident separation of closely spaced peaks and analysis of fine crystal structure.

Deep detector cooling

Thermoelectric cooling minimises detector thermal noise — critical for very weak signals and long integration times.

Maximum optical throughput

Up to 85% transmission efficiency gives a signal-to-noise ratio of up to 5000:1 and beyond.

Patented calibration

The built-in reference channel continuously compensates laser drift — absolute wavenumber accuracy measurement after measurement.

Broad spectral range

Covers both the low-frequency region from 70 cm⁻¹ and high-frequency modes up to 3700 cm⁻¹.
