Enhanced resolution

How does it work?

Visualize structures down to 120nm. Switching Laser Mode imaging (SLAM) is based upon the emission differential between Gaussian and annular laser excitation modes and raises the lateral resolution by a factor of two of any laser-scanning microscope. SLAM operates in both visible and infra-red excitations.


Greater performance

Turn on SLAM and acquire high resolution images rapidly from any sample

When installed in the VMS, SLAM can perform at a speed of 15 FPS (1024 X 512). It works brilliantly with live, fixed and cleared samples and can be used on living animals.

Rapid and versatile

Achieve higher resolution with less excitation

SLAM’s patented technology is not a depletion based approach and therefore is more gentle to the sample and functions with convential fluorescent dyes. SLAM can also be used on label-free techniques such as CARS, SHG/THG, FLIM and PLIM among others.

Compact and modular

Install SLAM on commercial and homemade confocal and multiphoton systems

The SLAM add-on is a small and compact module that augments your system’s current features, without any interference. SLAM works at the excitation level and is thus compatible with descanned and non-descanned detection systems.
