The term “nanotechnology” encompasses a variety of advanced research methods for investigating characteristic dimensions that are less than ~100 nanometers. Nanotechnology helps scientists and engineers develop faster electronics as well as ultrastrong and extremely light structural materials.
Of particular interest are nanotubes, which are created when carbon atoms bond to one another and form ubiquitous planar hexagonal rings (as in graphite or the benzene molecule). Researchers are investigating the formation of nanotubes in order to improve manufacturing processes and facilitate early detection of disease in medical science. When manufactured on a perfect molecular level, these fullerene tubes offer revolutionary electrical, thermal, and mechanical properties at the nanoscale.
There is also great interest in the optical properties of nanotubes, given their potential use as fluorescent tags in chemical and biological systems. For example, the development of next-generation in vivo optical imaging systems for disease screening and image-guided surgical interventions requires the use of brightly emitting, tissue-specific materials that optically transmit through living tissue1. Research being performed by scientists around the world has begun to demonstrate that fluorescence imaging in the NIR-II / SWIR range utilizing advanced materials such as single-walled carbon nanotubes (SWNTs) can provide superior in vivo sensitivity compared to fluorescence imaging in the NIR-I region.
Our novel NIRvana:640 InGaAs detectors use a 640 x 512 focal plane array to allow the capture of low-light fluorescence from advanced nanomaterials in the NIR-II / SWIR spectral region. These deep-cooled cameras, which provide sensitivity from 0.9 to 1.7 μm, have the ability to expose for as short as 2 μsec (up to many minutes). Ultra-low-noise readout electronics help ensure good signal-to-noise ratios even when the cameras are operated at their maximum rate of 110 full frames per second. Furthermore, excellent camera linearity means that they are highly reliable for scientific research.For nanotechnology imaging and spectroscopy applications in the spectral region from 200 to 900 nm, our PI-MAX4 family of ICCD cameras offers readout ranging from video rates to thousands of frames per second for capturing dynamics, while a sustained gating repetition rate of 1 MHz (2x better than most research-grade ICCD cameras available on the market today) allows these cameras to keep up with the ever-increasing repetition rates of lasers. These state-of-the-art ICCD cameras are also equipped with SuperSynchro and SuperHV technologies, which provide ultimate gating control in an easy-to-use configuration. Picosecond gating capabilities (<500 psec gating) are offered as well.
In addition, our 64-bit LightField software (available as an option for all of the cameras recommended above) provides a powerful yet easy-to-use interface that puts real-time online processing capabilities at the researcher’s fingertips.
