Every day, Princeton Instruments NIRvana systems facilitate revolutionary research in leading labs around the world. These compact cameras possess all the essential features for tackling demanding, low-light-level NIR / SWIR imaging and spectroscopy applications.

Widely recognized as a no-compromise camera platform, high-performance NIRvana systems are engineered for applications such as those involving NIR astronomy or photon-starved nanotube / quantum dot fluorescence.

Read the Case Study with Dr. Han Htoon from Los Alamos National Lab titled, "Measuring Spectra of Single Quantum Dot Nanocrystals Emitting in SWIR."

"The unprecedented long integration times and low dark counts [of the NIRvana:640LN] enabled single-nanocrystal spectral experiments, which cannot be achieved with conventional InGaAsdetectors for these dots."

–Dr. Han Htoon,
Center for Integrated Nanotechnologies (MPACINT)r,

NIRvana has received praise from many customers.

"The new InGaAs focal plane array detector has allowed our research group to easily extend our imaging spectroscopy techniques into the near-infrared regime. Combining a NIRvana with an eXcelon ProEM camera has enabled us to rapidly acquire 2D images from 400nm-1700nm on the same SP2300i spectrograph. Unlike other InGaAs 2D detectors we tested, the TE cooling and background subtraction features have allowed us to easily acquire long exposures to resolve photoluminescence from very dilute emitter samples."

Small Animal Imaging
For small-animal imaging in the NIR II / SWIR range, Princeton Instruments recommends the NIRvana:640 camera. We designed this 16-bit camera specifically for scientific research applications that require superb linearity and excellent near-infrared sensitivity.

Astronomical Imaging
Astronomical imaging can be broadly divided into two categories: (1) steady-state imaging, in which long exposures are required to capture ultra-low-light-level objects, and (2) time-resolved photometry, in which integration times range from milliseconds to a few seconds.


Singlet Oxygen Imaging
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.

Nanotechnology helps scientists and engineers create faster electronics as well as ultrastrong and extremely light structural materials.
