This pre-owned Topcon TRC‑50DX is a premium mydriatic fundus (retinal) camera engineered for advanced ophthalmic imaging. It is part of Topcon’s flagship line of retinal imaging systems, designed to meet the demands of digital imaging, angiography, and multimodal retinal diagnostics.

Multimodal Imaging Ability
The base TRC‑50DX supports color fundus photography, red-free photography, and fluorescein angiography (FA). The Type IA version expands capabilities further, incorporating fundus autofluorescence (FAF) and indocyanine green angiography (ICG) — useful in diagnosing retinal pigment epithelium (RPE) changes, choroidal neovascularization, and vascular pathologies.
User Interface and Ergonomics
A touch-screen control panel enables quick setting changes during workflow. The design includes ergonomic knobs for alignment and focusing adjustments. Green alignment dots provide visual cues to ensure proper working distance to the lens, enhancing ease of use during image capture.
Flash and Illumination Control
The TRC‑50DX employs a Xenon flash light system, adjustable through 21 discrete intensity levels (with half-step increments). This granular control allows clinicians to optimize illumination for varied patient eye pigmentation or media conditions.

Optics / Imaging Parameters
The instrument offers fields of view (FOV) of 50°, 35°, and 20°, facilitating both wide-angle and focused retinal imaging. Photographic magnifications at zero diopter are approximately 1.84× (50°), 2.45× (35°), and 4.28× (20°).
Diopter compensation for the patient’s eye typically spans –10 D to +6 D at the zero setting; extended settings allow ranges from –23 to –9 D, +5 to +23 D, or even +22 to +41 D for anterior imaging.
The optical head can swing/tilt to facilitate comfortable alignment, and the eyepiece is designed for wide-viewing distance to ease positioning and focusing.
Software & Connectivity
The TRC‑50DX integrates with IMAGEnet 6, Topcon’s imaging software platform that supports capture, processing, storage, and display of retinal images. The camera’s filter settings and CCD modules are automatically recognized, ensuring seamless workflow integration.
Clinical Applications & Advantages
The TRC‑50DX is suited for retina clinics, ophthalmology departments, and diagnostic imaging centers performing color fundus photography and angiography. Its modular design, optional advanced modes (FAF, ICG), and ease-of-use interface make it a versatile tool for diagnosing diabetic retinopathy, macular degeneration, retinal vascular diseases, and more. Its capacity to support different camera backends (film or high‑resolution digital sensors) makes it flexible for upgrades.
Considerations / Limitations
While the TRC‑50DX provides a rich feature set, its advanced modes (FAF, ICG) may only be available in the Type IA variant; users should verify unit type. Also, optical and mechanical alignment precision is crucial to maintain image quality, so regular calibration and maintenance are recommended.
