The Quest Spectrum Fluorescence Camera is the core compartment of the QUEST SPECTRUM®. This camera possesses a unique prism technology that simultaneously captures information from visible and near-infrared light sources in high definition (HD). By combining 3 sensors this technology allows for real-time visualization of the “visible” natural image and up to 2 “invisible” fluorescent images.

The information captured with the Quest Spectrum Camera can be visualized within several different fluorescence formats. Selecting the right image configuration is key for the surgeon to assess the information the system provides. The surgical screen consists of 2 modes. A full screen mode displaying one selected image view or an expanded mode showing 4 images on the screen. In the expanded mode 3 smaller images are displayed on the left side of the screen plus one larger image in the center. This mode allows the surgeon to quickly see all the information imaged by the camera. The surgeon can then select any of these images to be enabled in the center as the larger image.

The Quest Spectrum Ring Light

The Quest Spectrum Ring Light is attached to the Quest Spectrum Camera during open surgeries. The Quest Spectrum Ring Light is a sophisticated lens surrounded by an eight-piece Ring Light. The eight-piece Ring Light has an integrated light cable which connects to the Quest Spectrum Light Engine. This design is used to optimally illuminate the targeted area of the patient. Light reflected and emitted by the target area is projected to the Quest Spectrum Camera with minimal chromatic aberrations.

Quest Spectrum works with several Fluorescent Tracers

Depending on the specific surgery, different fluorescent tracers may be appropriate for visualization of the targeted tissue. The Quest Spectrum Light Engine and Fluorescence Camera can be tailored to activate fluorescence and capture images from several tracers. Customized configurations have been prepared for visualization of the following fluorescent tracers:


For research purposes only, not for clinical use

Indocyanine green (ICG):
 Methylene Blue

Cyanine 5 and 5.5 and 7: CW800

Fluorescein: ZW800

The Quest Spectrum is not limited to visualization of these fluorescent tracers. If you are not sure of the best available fluorescent label for your application, or if you wish to use a different fluorescent label, please contact us.
