The Imaging Chain
The sequence of events goes something like this:
- Light is generated by the Light source
- Light bounces off the target object and enters the scope
- Scope optics carry the image
- An imaging sensor captures the incident image
- A processor (CCU) shapes the image
- A monitor displays the image
- A recorder documents it.
If any link is weak, the final image can feel unstable, artificial, noisy, or fatiguing; especially in real cases with glare, fluid, blood, smoke, cautery haze, and rapid motion.
Introducing the Lucerna™ Premium HD (PHD) and Lucerna™ 4K Endoscopic Imaging Systems
The Lucerna™ platform was built around one simple idea: Give surgeons a view that feels believable and calm; so they can make confident decisions, reduce time spent making adjustments to the setup, and stay focused on the surgical procedure instead of having to spend time managing the endoscopic setup.
Lucerna’s goal is simple: Make the image behave — so the surgeon doesn’t have to.
That’s why we don’t describe Lucerna™ as “just a camera.” We describe it as an end-to-end imaging system designed to close the gap between what cameras typically show and what the human eye naturally distinguishes. Engineered to deliver a consistent surgical view and an OR workflow that teams can rely on case after case.
The real problem with endoscopic imaging today
Many systems can look sharp in perfect demo conditions. The real test is whether the image stays readable and trustworthy when the case gets messy:
- Bright reflections from wet tissue (glare)
- Dark pockets (shadow)
- Smoke, fog, haze during cautery or irrigation
- Fine mesh patterns that produce moiré artifacts
- Color drift that makes the tissue look unnatural
- Constant adjustments that break the surgeon’s rhythm
- Switching between rooms, scopes, and teams
When an imaging system forces the surgeon to manage the image, it steals attention from what matters most: the procedure.
The Endoscopic Imaging Chain
1) The scope: where the view begins
The scope is the optical “tunnel” inserted inside the patient. It defines the angle, field of view, and depth of field; basically, what kind of scene reaches the camera in the first place. Lucerna™ systems are designed to work with rigid and semi-rigid reusable scopes of all diameters and with a wide effective depth of field that supports smoother work with fewer refocus events.
2) The light source + light cable: your visual “fuel”
Without stable and correct illumination, even the best sensor will struggle. This is where our revolutionary light source platform Envolite comes into the picture. In real surgery, lighting changes constantly; scope movement, reflective tissue, fluid, and instruments all shift the scene brightness. Lucerna™’s platform’s algorithmic approach focuses on maintaining usable visibility under rapidly changing illumination conditions.
3) The coupler: the bridge between scope and camera head
The coupler is the optical adapter that transfers the scope image onto the sensor. If focus breaks when you zoom or move, the surgeon ends up “fighting the system.” That’s why the Lucerna™ platform endoscopic coupler emphasizes Focus and Forget™: set distance → focus once → zoom comfortably without constantly refocusing. Planes in the image stay sharp when the surgeon zooms in or zooms out.
4) The camera head: workflow in the surgeon’s hand
In the OR, control placement matters. Lucerna™ camera heads are designed for “eyes-up” operation. Key actions like white balance, capture, record, and freeze are available on the head, with programmable buttons to match surgeon preferences.
- Both PHD and 4K camera heads are specified with IPX7 protection and a flexible 3.0 m cable.
- Heating has been reduced to negligible levels even after 24 hours of continuous operation.
- The camera head has the lowest weight in the market to reduce fatigue.
5) The sensor: where clarity and confidence truly start
The next-gen TrueChip™ sensor significantly enhances the current 3-chip state-of-the-art by adding three more CMOS sensors to the RGB sensors (+ OCV – Orange, Cyan, Violet), realizing a 6-chip integrated CMOS to convert light into signal.
- This eliminates teething issues like heat and recurring service needs.
- The Lucerna™ 4K system specifies a 10 MP sensor feeding a native UHD pipeline.
6) The CCU: the brain that makes the image “surgical”
The CCU (Camera Control Unit) processes the sensor output into a stable, controllable, OR-ready image. Lucerna™ CCUs are built around real surgical controls like:
- White balance modes (AWB/ATW)
- Dark-zone improvement and highlight suppression
- Noise reduction and de-moiré modes
- Surgical scene presets and calibrated specialty modes
7) The monitor: what the whole team trusts
A surgical monitor must match the system’s output and color handling.
- Lucerna™ 4K recommends UHD monitors with HDMI 2.0 and color modes like BT.709 and BT.2020.
- Lucerna™ PHD supports medical monitor compatibility for 1080p workflows.
8) The trolley/workstation: standardization and repeatability
Lucerna™’s positioning includes a clean mobile stack and standardized workflow to reduce clutter and setup errors, providing a repeatable setup across rooms and specialties.
One platform. Multiple configurations.
Lucerna™ is a series designed to scale across different OR needs while maintaining a consistent “Lucerna™ look and feel.”
- Lucerna™ Premium HD (PHD) — designed as the dependable workhorse for premium HD clarity and stable workflow.
- Lucerna™ 4K — designed for teams that want maximum detail and next-level visibility tools in 4K environments.
