Quest Spectrum Platform, available through IEL

The Quest Spectrum Platform is designed and developed for open and minimally invasive image-guided surgery. Our technology enables surgeons to create contrast between biological tissues that are indistinguishable with the naked eye.

This contrast is created by using fluorescent imaging; a revolutionary method in which biological structures are visualised with fluorescent tracers. The Quest Spectrum Platform is a medical device that is able to visualise the fluorescent tracers. Due to the imaging in the near-infrared, just outside the spectrum visible for humans, the system can provide the additional information to the surgeon to improve their decision-making-process during surgery.


The Quest Spectrum Platform is the most advanced total solution for intraoperative fluorescence imaging. The key benefits of the Quest Spectrum Platform are:

  1. Simultaneously capturing (no switching) of natural coloured images and up to two fluorescent images.
  2. Usage for open and laparoscopic procedures in one medical device.
  3. Capturing High Definition (HD) images with great sensitivity due to dedicated sensors.
  4. Recording real-time videos and stills/photos.
  5. Stabilising arm provides stabilisation and positioning of the camera, without requiring assistance from other OR personnel

Benefits of the Quest Spectrum™ Camera:

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

The information captured with the Quest Spectrum Camera can be visualised in two different modes as shown on the right. In the first mode, the standard colour image is separately evaluated from the fluorescent image to clearly identify the fluorescent active tissues. In the second mode, the natural image is overlaid with one of the fluorescent images. This allows direct assessment of the location of the targeted tissue without any delay.

Quest Spectrum™ Optics


The Quest Spectrum Platform is specially designed to combine the procedures of open and laparoscopic surgery by simply switching the attachment of the Quest Spectrum Camera. When the surgeon has the urge to make the switch, this switch can be performed during surgery. The Quest Spectrum Ring Light is used for open procedures and the Quest Spectrum Laparoscope is used for laparoscopic procedures.


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 connected to the Quest Spectrum Light b Engine. This design is used to optimally illuminate the targeted area of the patient. Light reflected and emitted by the patient is projected to the Quest Spectrum Camera with minimal chromatic aberrations.

Quest Spectrum™ Light Engine


The Quest Spectrum Light Engine has been developed to generate white and near-infrared light that can be used in both operating modes of the Quest Spectrum Platform. The light generated by the Quest Spectrum Light Engine illuminates the surgical field. Illumination of the surgical field using the near-infrared part of the light excites the fluorescent tracer which in turn emits light towards the Quest Spectrum Camera. The lasers and LEDs in the Quest Spectrum Light Engine are designed in a modular fashion. This allows us to adjust the properties of the Quest Spectrum Light Engine to your applications.

The Quest Spectrum™ Platform is available through IEL in the UK and Ireland and sold by Quest.
