Enabled by its rapid (20 MHz) ADC readout capability and 300 nsec/row vertical shift speed, the new
ProEM-HS:512BX3 model delivers > 60 full frames per second. Furthermore, this next-generation camera provides >1,000 fps in imaging mode and >10,000 fps utilizing special high-speed, custom readout modes. Operation is made simple by Princeton Instruments’ powerful, intuitive and user friendly LightField® software.

 

Thanks to all-metal, hermetic vacuum seal technology that comes with the industry’s only lifetime vacuum guarantee, these ProEM-HS cameras are thermoelectrically cooled to below -90°C using air and liquid for worry-free operation. Other advanced features include a built-in light source for precise electron multiplication (EM) gain calibration, as well as excellent baseline stability, hardware time-stamping, and a Gigabit Ethernet data interface.

 

“When we set out to design our next-generation ProEM cameras, we knew it would be a tall order,” reflects Ravi Guntupalli, vice president of sales and marketing at Princeton Instruments. “Yet our engineering team not only managed to make these cameras two times faster but also improved their noise performance — even at lower speeds. This is one of the best EMCCD camera offerings on the market for low-light imaging and spectroscopy applications such as single-molecule fluorescence [SMF], astronomy, Bose-Einstein condensates [BECs], and plasma studies.”

 

New ProEM-HS cameras are fully compatible with Princeton Instruments’ LightField 64-bit application software, which provides complete control of camera features via a cutting-edge graphical user interface. For researchers requiring a custom interface, toolkits for National Instruments’ LabVIEW® and MathWorks’ MATLAB® are available, as are free software development kits (SDKs). The new high-speed EMCCD cameras have also been designed for easy integration with award-winning Princeton Instruments IsoPlane® spectrographs to further leverage their excellent imaging and spectroscopic performance.

IsoPlane and PIXIS used to explore the optical properties of gold nanoparticle arrays

Princeton Instruments congratulates Prof. Jing Zhao of the University of Connecticut on the recent publication of  “Blue Shifted Narrow Localized Surface Plasmon Resonance from Dipole Coupling in Gold Nanoparticles Random Arrays” (J. Phys. Chem. C, 2014, DOI: 10.1021/jp508181g).

Dr. Zhao and her co-workers used a Princeton Instruments IsoPlane SCT-320 aberration-corrected spectrograph in conjunction with a Pixis:1024BR deep cooled CCD camera to explore the optical properties of gold nanoparticle arrays. In these self-assembled nanostructures, long-range dipole coupling is shown to profoundly influence the peak wavelength and width of the surface plasmon resonance peak. Figure 1 (below), for example, shows light scattering spectra of identical gold nanoparticles deposited on a surface, isolated as single particles, or in bulk solution. Highly specific methods for functionalizing gold NPs to bind to different molecules are now available. Hence, the sensitivity of the optical properties to the local dielectric environment, as modified by the presence of bound or adsorbed target molecules, points toward the use of functionalized gold NP arrays as exquisitely sensitive probes for chemical sensing by optical imaging and spectroscopy.

IsoPlane and NIRvana used in recent biophotonic nanotube research

Dan Heller and coworkers at Memorial Sloan-Kettering Cancer Center describe important advances in noncovalent functionalization of carbon nanotubes in a recent issue of Journal of the American Chemical Society (DOI: 10.1021/ja505529n). Carbon nanotubes are uniquely valuable biophotonic probes due to their intense, non-quenchable emission within the NIR-SWIR tissue transparency window from 900-1600 nm. Encapsulating CNTs with helical polymers enables switchable modulation of the photoluminescence intensity and excitonic energy transfer between individual CNTs, as shown in [Figure S5 from Supporting Information] . The researchers used a Princeton Instruments IsoPlane SCT-320 spectrograph and Pio-NIR (now NIRvana) imaging InGaAs detector in this work.

Monitoring of Singlet Oxygen in individual cells made simple by NIRvana: 640, Princeton Instruments 2D array InGaAs camera

Princeton Instruments is pleased to recognize the innovative work of the Optical Spectroscopy Group headed by Jan Hála within the Department of Chemical Physics and Optics at Charles University (Prague, Czech Republic). A recently published paper* in Photochemical & Photobiological Sciences details the group’s development of a new experimental setup that enables direct microspectroscopic monitoring of singlet oxygen using NIRvana: 640, a 2D-array InGaAs camera specially designed for scientific research with excellent linearity and near-infrared sensitivity (Marek Scholz, Roman Dědic, Jan Valenta, Thomas Breitenbach and Jan Hála: Real-time luminescence microspectroscopy monitoring of singlet oxygen in individual cells, Photochem. Photobiol. Sci., 2014,13, 1203-1212, DOI: 10.1039/C4PP00121D).

Singlet oxygen, the first excited state of molecular oxygen, is a highly reactive species that plays an important role in a wide range of biological processes, including cell signaling, immune response, macromolecule degradation, and elimination of neoplastic tissue during photodynamic therapy. Often, a photosensitizing process is employed to produce singlet oxygen from ground state oxygen.

The researchers at Charles University in Prague utilized two detection channels (VIS and NIR) to perform real-time imaging of the very weak near-infrared phosphorescence of singlet oxygen and photosensitizer simultaneously with visible fluorescence of the photosensitizer. Their new experimental setup enables acquisition of spectral images based on singlet oxygen and photosensitizer luminescence from individual cells, where one dimension of the image is spatial and the other is spectral, covering a spectral range from 500 to 1700 nm.

To achieve these results, a Princeton Instruments NIRvana® 640, 2D InGaAs camera was coupled to an imaging spectrograph (Acton SpectraPro® 2500i, Princeton Instruments). According to Dr. Marek Scholz, the main advantage of the near-infrared–sensitive NIRvana camera over previously utilized 1D InGaAs detectors is the NIRvana detection array’s two-dimensionality, which leads to a dramatic reduction of acquisition times and avoids some of the problems caused by photobleaching of the sample. A back-illuminated, silicon CCD camera (Spec-10:400B, Princeton Instruments) was used to detect visible light in the setup.

Scholz et al. indicate that the introduction of spectral images for such studies addresses the issue of a potential spectral overlap of singlet oxygen phosphorescence with NIR-extended luminescence of the photosensitizer and provides a powerful tool for distinguishing and separating them, which can be applied to any photosensitizer manifesting NIR luminescence.

“The large 27.6 mm x 27.6 mm imaging area of the new PI-MAX4:2048f ICCD camera is truly a compelling advantage, as it allows significantly more data collection for experiments in which time is critical and the samples themselves may have been difficult to procure,” explains Scott Young, Imaging Product Manager at Princeton Instruments. “Key application areas include shock wave physics, neutron research, combustion studies, and planar laser-induced fluorescence [PLIF]. This state-of-the-art camera will provide more publication-ready data in less time, enabling researchers to focus on science instead of their equipment.”

The highly sensitive PI-MAX4:2048f, with Gen II or Gen III filmless intensifiers, is the only ICCD camera on the market today to offer high frame rates at 6 MHz / 16-bit digitization, as well as a 1 MHz sustained gating repetition rate. An integrated programmable timing generator, SuperSynchro, built into the new camera makes it ideal for time-resolved imaging and spectroscopy applications.

Furthermore, the latest Princeton Instruments LightField® data acquisition software, available as an option, affords complete control over all PI-MAX4 hardware features via an exceptionally intuitive user interface. LightField provides precision exposure control and a host of innovative functions for easy capture and export of imaging and spectral data.
