sSNOM & AFM-IR
with APE's MID-IR Laser Carmina
Combine s-SNOM and AFM-IR with a Remarkable Mid-IR Laser
Broadly Tunable IR Laser for the Integration with Scattering SNOM and AFM-IR Microscopes
APE provides a tunable MId-IR laser spectroscopy, and for the integration with scattering SNOM and AFM-IR microscopes.
The laser sets new standards in resolution and tuning range due to its OPO/DFG architecture. The unique combination of 300 cm-1 broadband as well as 20 cm-1 narrowband emission covers the two complementary nanoscale IR techniques s-SNOM and AFM-IR.
The outstanding high output power between 5 mW and 300 mW in combination with an extremely low noise level is addressing a wider range of applications in the near-field imaging & spectroscopy field.
A pulsed mode (Burst Mode with 50 % Duty Cycle) is included for AFM-IR applications.
