CellView WR-1 Retinal Imaging System

CellView’s WR-1 is a retinal imaging system used by clinicians to capture widefield images of the retina, supporting screening, diagnosis, and monitoring through an optomechanical platform designed to image deep into the periphery of the eye.

The Challenge:

CellView was developing a retinal imaging system where performance depended on how optics, motion control, structural packaging, and enclosure design worked together. The challenge was not whether individual elements could perform, but whether they would remain stable and controllable once integrated.

The work began around motorized optical adjustment, but the implications extended beyond a single subsystem. Key architectural elements were still evolving, which required early decisions to remain flexible enough to support the broader system as it took shape.

As development progressed, several constraints became more defined. Optical performance relied on precise and repeatable alignment. Internal packaging needed to accommodate optics, electronics, and clinical-use geometry within a limited volume. The chassis had to maintain stability while allowing controlled adjustment where required. Assembly access also needed to reflect how the device would be built and aligned in practice.

Prototype activity made these constraints more visible. Adjustment sensitivity, access limitations, and mounting behavior began to appear together. These were expected outcomes in a system where interfaces were still being resolved.

The work shifted toward establishing greater control across these interfaces so the system could be built, tuned, and repeated more reliably.

A later phase focused more narrowly on optical and mechanical subsystems where alignment control and assembly sensitivity had the greatest impact on build consistency.

The Approach:

We approached the WR-1 by focusing on the interfaces that governed system behavior, particularly where optical performance, mechanical stability, and assembly intersected.

The initial effort defined the focus mechanism as a controlled motion system with clear positioning behavior, tolerances, and mounting strategy. This provided a more stable reference for integrating optical elements and resolving packaging decisions.

The work then expanded into system-level packaging. Optical, mechanical, and electronic components were resolved within the physical constraints of patient interaction. Layout decisions were guided by sightlines, clearances, and access for adjustment, ensuring the system could be integrated and used as intended.

As prototypes were built, attention moved to interface refinement. Adjustment features were introduced where precision was required. Mounting strategies were updated to improve stability and reduce unintended interaction between components. Access points were refined to support practical alignment and installation.

Components and subassemblies were also revised to improve installation flow and reduce variability during builds. These changes improved how the system could be assembled and tuned without introducing additional complexity.

Manufacturing considerations were addressed in parallel. Supplier inputs, component selection, and assembly sequencing were incorporated early so that prototype learning could translate into a more consistent build approach.

In a later engagement, the work concentrated on optical subsystems and supporting mechanical architecture. Alignment control was improved, adjustment mechanisms were clarified, and assembly sensitivity was reduced in areas where precision was most critical.

The focus remained consistent throughout. Increase control at the interfaces so system behavior could be maintained in practice.

The Outcome:

The WR-1 developed into a more stable and buildable retinal imaging platform, with improved control across both the core system architecture and the most sensitive optical and mechanical areas.

Key outcomes included:

A chassis and enclosure architecture better aligned with optical, electronic, and clinical-use requirements
Functional prototypes and validation units that supported testing and early-stage use
A clearer path into engineering builds, supported by BOM refinement, supplier coordination, and improved manufacturability
Multi-axis adjustment strategies that enabled more precise optical alignment and controlled tuning

A motorized focus mechanism that enabled controlled optical positioning and supported system integration
Assembly architecture improvements that reduced build friction, improved access, and lowered variability across units
Refined illumination and camera subsystem architecture designed for more consistent integration and alignment
A more defined interface structure across optics, motion, chassis, and manufacturing planning
