Topcon NW400 — Refurbished Non-Mydriatic Fundus Camera with Windows 10
The Topcon NW400 (TRC-NW400) is a fully automated non-mydriatic fundus camera designed for fast, single-touch retinal screening — the workhorse model that put automated true-color fundus photography within reach of primary-care eye clinics and optometry practices. This refurbished topcon nw400 ships with a Windows 10 capture computer and IMAGEnet software, ready to run on day one.
The TRC-NW400 acquires fundus images through pupils as small as ø3.3 mm in small-pupil mode (ø4.0 mm at full 45° angle), with auto-alignment, autofocus, and auto-shoot driven by a single touch of the rotating panel. A low-intensity 4.0 Ws flash combined with high-sensitivity capture produces sharp, true-color images while keeping patient discomfort to a minimum.
According to a National Library of Medicine-indexed multicenter study (Int J Gen Med, 2023), non-mydriatic fundus cameras deliver high diagnostic sensitivity for referral-warranted diabetic retinopathy in primary-care settings — making the NW400 a strong fit for chronic-disease screening programs that need fast, undilated capture at the front desk or pre-test station.
Why Practices Choose the NW400
Fully automated single-touch capture — auto-alignment, autofocus, and auto-shoot mean a tech can image both eyes with one finger. Throughput stays high even with rotating staff.- Small-pupil mode (ø3.3 mm) — capture undilated eyes that would defeat older cameras. Critical for screening older patients and small-pupil clinical populations without dilation drops.
- 45° / 30° field of view — full-angle 45° captures the posterior pole; 30° digital zoom highlights the disc and macula. Standard montage workflows are supported by the 9 fixation targets.
- 9 internal fixation targets — 3 traditional positions (nasal, central, temporal) plus 6 peripheral targets for wide-angle composite imaging. Documents periphery without the patient turning their head.
- Low 4.0 Ws flash — high sensitivity capture with reduced flash intensity keeps patient discomfort low and works well on photophobic or post-cataract patients.
- 360° rotating touch panel — the operator can stand on either side of the patient or against a wall. Compact footprint fits tight pre-test rooms.
- DICOM / IMAGEnet ready — direct DICOM compliance integrates with most PACS and EMR systems. Capture computer is pre-loaded with Topcon IMAGEnet 5 for immediate use.
- Stereo photography mode — automated alignment for stereo-pair acquisition, useful for disc evaluation in glaucoma and retinal-edema follow-ups.
Clinical Applications
- Diabetic retinopathy screening — fast undilated capture for chronic-disease primary care, optometry, and tele-retinal programs.
- Glaucoma disc documentation — stereo-pair acquisition supports cup/disc ratio evaluation and progression tracking.
- Macular degeneration follow-up — true-color images document drusen, geographic atrophy, and pigmentary changes over time.
- Hypertensive retinopathy and vascular review — vessel caliber and AV nicking are clearly documented in true color.
- Pre-cataract and pre-refractive baseline — quick screening fundus before surgical referral.
- Pediatric and small-pupil patients — small-pupil mode and low flash make image capture practical without dilation.
Who This Is For
- Optometry and primary-care ophthalmology practices building or expanding a fundus-imaging workflow without committing to a $30K+ premium camera.
- Tele-retinal and diabetic-screening programs that need DICOM output and high-throughput single-touch capture.
- Multi-doctor practices replacing a legacy NW8 or NW6 with a smaller-footprint, fully-automated successor.
- Mobile and satellite clinics where the compact NW400 footprint and rotating panel save valuable space.
