Periapical X-ray
ROSON RoRay
The RoRay is a handheld portable dental X-ray engineered for the Filipino clinic. Premium diagnostic specs, no wall installation, ready in 30 minutes of unboxing.
- 0.4 mm ultra-fine focal spot
- Full-coverage lead shielding
- 2.8″ HD onboard display
- Self-cooling, no warm-up
The engineering
Four pillars of why the RoRay outperforms its price tier.
Image quality
0.4 mm Ultra-Fine Focal Spot
Premium-tier diagnostic clarity. A smaller focal spot equals sharper image detail — every periapical, every bitewing, every diagnosis.
Operator safety
Full-Coverage Lead Shielding
Lead shielding wraps the tube head on every face — not only the front. Combined with a potting-encapsulated tube assembly, leakage radiation is below standard requirements.
Workflow
Onboard HD Display, Cordless Operation
2.8-inch HD color display. No tablet companion required. Self-cooling tube — no warm-up wait, no cooldown between exposures.
Focal spot, explained
Why 0.4 mm is the difference between “image” and diagnosis.
The focal spot is the area on the X-ray tube’s anode where radiation originates. Smaller spot, sharper image. The RoRay’s 0.4 mm sits in the premium diagnostic clarity tier — every periapical lesion, every hairline crack, every accessory canal.

Double protection
5,000 holds per year. Safety isn’t a feature — it’s the foundation.
A dentist taking 20 X-rays a day, 250 days a year, will hold a handheld X-ray unit roughly 5,000 times in a single year. The RoRay is engineered for that lifetime of exposure — operator safety designed in, not retrofitted.
Layer 1 · Full-Coverage Lead Shielding
Lead wraps every face of the tube head — front, sides, rear. Independently tested leakage measures below standard requirements, even at maximum exposure settings.
Layer 2 · Solid-State Potting-Encapsulated Tube
The tube and shielding are permanently sealed together as a single solid-state assembly — eliminating the air gaps where microdoses of radiation can leak through.
The complete kit
One brand. One warranty. One service line.
The RoRay handles emission. The ROSON Rosensor handles capture. A complete digital radiography kit from a single manufacturer — no mix-and-match warranty chains, no cross-vendor finger-pointing.

From film to digital
Going digital eliminates the darkroom — and with it the daily exposure to materials that were never meant for human contact.
- Toxic developer & fixer chemistry
- Lingering chemical fumes & odor
- Daily darkroom & staff exposure

No wall mounting. No electrician. No architect. Charge unit, install driver, operational from delivery in under an afternoon.
Built for Filipino practice
Six clinic profiles where RoRay wins.
Film-era clinics going digital
Replace your darkroom and film chemistry. RoRay + Rosensor is an entry-level handheld kit, no wall installation required.
Rural and provincial clinics
No wall-mount infrastructure needed. The RoRay works anywhere a dentist can hold it — including clinics without dedicated X-ray rooms.
Multi-operatory clinics
A single handheld unit shared across chairs costs 3–5× less than wall-mounting every operatory.
Mobile and outreach services
Truly portable — fits in a bag. Perfect for medical missions, dental caravans, and barangay outreach programs.
New clinic builds
Skip the architect drawings for a shielded X-ray room. Open digital from day one with a complete kit from one supplier.
Pediatric clinics
Handheld flexibility lets you angle around squirming patients. No wall arm to fight, no rigid sensor positioning.

Common questions
Answers, before you ask.
What is the ROSON RoRay handheld dental X-ray?+
The ROSON RoRay is a handheld portable dental X-ray unit designed for intraoral periapical and bitewing imaging. It uses a high-frequency, solid-state potting-encapsulated tube with a 0.4 mm ultra-fine focal spot — premium-tier diagnostic clarity in a handheld form factor. Unlike wall-mounted X-ray systems, the RoRay requires no installation, no electrical work, and no dedicated operatory. Operated one-handed at the patient chair.
Why does a 0.4 mm focal spot matter?+
The focal spot is the area on the anode where X-rays originate. Smaller focal spot equals sharper image detail. Industry classification: 0.8–1.0 mm is large (budget/legacy), 0.6 mm is medium, 0.5 mm is small, and 0.4 mm is ultra-fine. The RoRay’s 0.4 mm focal spot sits in the premium diagnostic clarity tier — every periapical lesion, every hairline crack, every accessory canal.
How long does the RoRay tube last?+
The high-frequency X-ray tube is independently validated to 100,000 exposure cycles with less than 5 percent sharpness attenuation over the tube lifespan. For a clinic shooting 20 X-rays per day across 250 working days per year, that is approximately 20 years of use at rated specification — well beyond the realistic ownership horizon of any clinic.
Is the RoRay safe for the dentist holding it?+
Yes. The RoRay uses ROSON’s Double Protection design: 9% full-coverage lead shielding wraps the tube head on all sides (not only the front face, where many handheld competitors stop), combined with a solid-state potting-encapsulated tube assembly that permanently seals the tube and shielding together. The result is leakage radiation below standard requirements, which matters for dentists who take thousands of X-rays per year.
How long does the battery last?+
The RoRay supports 50,000+ imaging exposures per battery cycle, implying multi-day operation between charges — standard for premium handheld units. The 2.8-inch HD color display shows exposure parameters (kVp, mA, exposure time) without requiring a separate tablet companion.
Does the RoRay work with digital sensors?+
Yes. The RoRay pairs with the ROSON Rosensor (intraoral digital sensor) over USB to your existing clinic PC for a complete single-brand digital radiography kit. One supplier, one warranty chain, one service line. The Rosensor is IP68-rated with a 20 micron pixel and 14-bit imaging.
What clinics is the RoRay best suited for?+
Filipino clinics upgrading from film to digital, rural and provincial clinics without wall-mount infrastructure, multi-operatory clinics that want a single unit shared across chairs, mobile and outreach dental services, new clinic builds wanting a complete kit from one supplier, and pediatric clinics where flexible positioning matters for squirming patients.
