The NESSIE scanning microscope by MONSTR Sense Technologies is a first-of-its-kind laser-scanning microscope. The microscope rapidly raster scans the laser input over your sample, and features an optical design that eliminates a beam offset that is typical in scanning microscopes. For those working with a cryostat or otherwise fixed sample: the objective height is variable by up to 5″, and the sample area is very large. The NESSIE microscope is a standalone microscope that may integrate just about any laser-based measurement with high resolution imaging, and it is designed to integrate well with our BIGFOOT ultrafast spectrometer,
Laser scanning with no beam offset
Typical laser-scanning microscopes use two X and Y scanning mirrors that are placed near each other to scan the laser. Because neither mirror is at an image plane of the optical system, the beam drifts as the image is scanned. The MONSTR Sense design places both the X and Y scanning mirrors at an image plane, using parabolic mirrors as a relay system between the scanning mirrors, to eliminate the beam drift at the back focal plane of the objective. Parabolic mirrors benefit you by introducing no temporal chirp and negligible loss.
Vignetting is reduction of image brightness near the image periphery. Though this effect may be great for a photo filter, in microscopy it distorts data and reduces the field of view. Laser scanning using scanning mirrors that are just mounted close together, which is common in commercial and homemade scanning microscopes, introduces substantial vignetting. Our design eliminates this effect over the entire microscope objective’s field of view.
Enables heterodyne detection
Because the beam reflected off of the sample (the output beam) propagates exactly back along the input beam path, the output beam does not drift during laser scanning. Therefore, heterodyne detection between a local oscillator beam and the signal is possible with NESSIE.
Adjustable height and large sample area
Designed to operate with commercial cryostats
Cryostats come in many sizes and shapes. Fitting these under a typical microscope requires adapter plates and unstable stages, but not any more! The NESSIE microscope will conform to your sample. The entire microscope can be raised to clear an object with a height less than 4″ to over 8″. The clearance between the center of the objective and the microscope supports and housing is 5.5″.
High stability maintained
By using separate support and lifting mechanisms, we maintain high stability and alignment of the height-adjustable microscope. This stability is essential for generating high resolution images in environments where closed loop cryostats and other equipment generate vibrations.
Merging NESSIE with our BIGFOOT Ultrafast Spectrometer
When combined with our BIGFOOT Ultrafast Spectrometer, the complete system is powerful. Acquire ultrafast movies in seconds, and zoom in on regions of interest for higher resolution scans.
On an overview image select a set of points and completely characterize the electronic and vibrational modes at each of those points with BIGFOOT’s full set of coherent techniques.
Interested in one coherent feature in particular? Measure images with one of our many functional image modes.
The NESSIE microscope is designed to handle a wide range of wavelengths and provide imaging control over the entire microscope objective’s field of view. Imaging controls include: pixel resolution, scan rate, and region of interest. When merged with the Bigfoot, NESSIE allows you to completely correlate electronic structure with spatial inhomogeneity using decay constant maps and hyperspectral images.
