The Stuttgart Instruments Piano is a tunable infrared source for precision spectroscopy and microscopy. It provides narrow linewidth, automated wavelength control, and repeatable spectral settings. The pump laser is integrated in the same enclosure.
- Integrated pump laser
- Integrated high-speed modulator
- Fully automated wavelength control
Configurations
Standard Piano configurations
Piano is delivered as a single selected configuration (Standard Piano or extended-range Piano MIR). In contrast to Alpha, where multiple output modules can be combined within one system, Piano is specified around one target range. Values are representative. Ask us for a configuration-specific datasheet.

Performance
Spectral accuracy
The Piano sets and holds its wavelength under automated control, with a narrow linewidth and repeatable tuning steps for high-resolution spectroscopy.
- Narrow, precisely tunable linewidth
- Repeatable, gap-free wavelength steps
- Passive long-term stability without active locking
Modulation
Integrated high-speed modulator
The Piano is equipped with a high-speed optical modulator. All outputs are modulated through a single input signal, with a fully integrated modulation architecture and full software support.
- Modulation frequency 1 kHz – 3 MHz
- Duty cycle 0 – 100%
