Product Description
|
The MCL-NSOM is a fully operational near field scanning optical microscope. It has been built on Mad City Labs versatile RM21™ inverted optical microscope which allows users to convert between NSOM, SPM, and fluorescence optical microscopy techniques.
The MCL-NSOM builds on our successful resonant probe SPM and incorporates common elements such as the MadPLL® phase lock loop controller. The NSOM also exploits our expertise in precision motion control by including six axes of motorized positioning, for the sample and NSOM probe, and three axes of closed loop piezo nanopositioning to provide exceptional position resolution and accuracy.
The MCL-NSOM also includes a 635nm laser excitation source, fiber launch, oil immersion objective lens (20x, 0.4 N.A.), CMOS alignment camera and avalanche photodiode detector. The microscope configurable design allows researchers to tailor the instrument for many different optical microscopy techniques including near field spectroscopy.
The MCL-NSOM is operated in aperture mode with shear force feedback. The standard 5 modes are supported: illumination, collection, illumination and collection, reflection and reflection collection. We supply a LabVIEW™ based software package which automates the motion control features.
