Welcome!
ACTOPROBE LLC designs, manufactures, and sells custom optical Spectroscopy/Microscopy Instruments and AFM Probes for conventional AFM to do single molecular spectroscopy of biomedical specimens and compound semiconductor material & devices. The company was founded in March 2009.
We provide you with an accessory to your existing AFM to do optical microscopy and spectroscopy on a single molecular level. Also, we offer you the most affordable AFM if you need one.

Publications
Novel near field active optical probe with ultra fast short pulses
Novel semiconductor-laser-integrated active AFM optical probe with ultrashort pulses and nanoscale aperture is demonstrated with 3.5 ps pulse width and 11.4 GHz repetition rate.
Novel semiconductor-laser-integrated active AFM optical probe with ultrashort pulses and nanoscale aperture
We have demonstrated a novel type of AFM probe – Ultra-Fast AFM Active Optical Probe (UFP AAOP) by monolithically integrating a mode-locked diode laser and AFM tip.
Tip-enhanced stimulated Raman scattering with ultra-high-aspectratio tips and confocal polarization Raman spectroscopy for evaluation of sidewalls in Type II superlattices FPAs
Actoprobe team had developed custom Tip Enhancement Raman Spectroscopy System (TERS) with specially developed Ultra High Aspect Ratio probes for AFM and TERS measurements for small pixel infrared FPA sidewall haracterization.
Confocal Raman Spectroscopy and AFM for Evaluation of Sidewalls in Type II Superlattice FPAs
We propose to utilize confocal Raman spectroscopy combined with high-resolution atomic force microscopy (AFM) for nondestructive characterization of the sidewalls of etched and passivated small pixel focal plane arrays (FPA) fabricated using LW/LWIR InAs/GaSb type-II strained-layer superlattice (T2SL) detector material.
