NSOM - Near Field Scanning Optical Microscope System
Near Field Scanning Optical Microscope System
Mad City Labs NSOM
The MCL-NSOM is a near field scanning optical microscope, based on the Mad City Labs versatile RM21™ microscope platform, that offers NSOM, SPM, and fluorescence optical microscopy techniques in a single package.
The MCL-NSOM combines Mad City Labs' successful SPM resonant probe, the MadPLL® phase lock loop controller, and several of the company's precision positioning elements. For example, the NSOM includes six axes of motorised positioning for the sample and NSOM probe, and three axes of closed loop nanopositioning for exceptional position resolution and accuracy.
Other key items supplied are: a 635 nm laser excitation source with fibre launch, a 100x 1.25 N.A. oil immersion objective lens, an avalanche photodiode detector, a CMOS alignment camera, and various tuning fork probes (image right).
The microscope's versatile design allows researchers to configure the instrument for many different optical microscopy techniques such as:
Resonant probe AFM
Near field spectroscopy
Fluorescence & epifluorescence microscopy
The MCL-NSOM operates in aperture mode, supporting illumination; collection; illumination and collection; reflection and reflection collection, with shear force feedback. Mad City Labs supply a LabVIEW™ based software package which automates the motion control features.
