Visionstar SJG-800

The SJG-800 is aimed at optical practices and laboratories that want scanning, centring and edging on site, with room to grow into a linked set-up. In an independent optical practice, the scanner can sit at the dispensing desk, where a frame is traced in half a second while the customer is present, and the edger can work in the back room.

Dispensing opticians and optical technicians benefit from the scanner's real-time imaging guidance. The screen shows when the centre position has been reached, and the scanner removes the effect of lens power, prism and artificial parallax from its reading. The capacitive touch screen tilts from 20° to 100°, so it can be angled for a seated or standing operator.

Glazing staff work with pressure settings on the edger. Clamping pressure is adjustable in three steps, and grinding pressure can be varied to suit different lenses. Bevels and flat edges can both be polished, which covers full-rim frames as well as rimless and semi-rimless styles.

Optical laboratories with a growing order book can connect one scanner to two main machines and use the online function for networked operation. Two RS8000 automatic milling machines linked to one scanner form a processing centre.

Hospital eye departments and eye clinics with an on-site glazing area can use the system to complete spectacles for patients within the building, keeping the compact scanner in the clinic and the edger in a separate room.

Eyewear retailers with a central workshop can link scanners and edgers to build a small processing line around their branches.

A half-second scan

The scanner captures the frame shape in 0.5 seconds.

Centring confirmed on screen

Real-time imaging guidance shows the operator when the centre position has been reached.

Readings through prescription lenses

Lens power, prism and artificial parallax effects are removed automatically during the scan.

Pressure set for the lens

Clamping pressure adjusts in three steps, and grinding pressure can be varied for different lenses.

Polished bevels or flat edges

Both edge styles can be polished, covering full-rim, rimless and semi-rimless work.

Room to expand

One scanner connects to two main machines, and the online function supports networked operation.

A screen that angles to the user

The 7-inch capacitive screen tilts from 20° to 100°.

Compact scanner

At 240 × 180 × 130 mm, the scanner fits on a dispensing desk or counter.

Combined scanning and centring

Optical scanning and centre positioning are carried out together on the scanner.

0.5-second frame scan

The frame shape is captured in half a second.

Real-time imaging guidance

Shows when the centre position has been reached.

Automatic power and prism removal

Removes the effect of lens power, prism and artificial parallax from the scan.

7-inch capacitive touch screen

1280 × 800 true-colour resolution, tilting from 20° to 100°.

Two-machine connection

One scanner can connect to two main machines at the same time.

Lens size range

Diameters from 22 to 80 mm.

100 mm wheel

The edger grinds on a 100 mm wheel.

Three-step clamping pressure

Clamping pressure is adjustable across three settings.

Variable grinding pressure

Grinding pressure can be varied to suit different lenses.

Bevel and flat-edge polishing

Both bevels and flat edges can be polished.

Online function

Supports networked operation of the edging system.

Power consumption

Edger 550 W, scanner 60 W.

The SJG-800 (HY-800) suits an optical practice, laboratory or eye clinic that wants to scan, centre and edge lenses on site, with the option of linking machines later. Practices starting in-house glazing, laboratories planning a networked set-up and retailers with a central workshop will gain the most. Its strength is a quick, guided scan paired with pressure control at the edger. A 0.5-second frame trace with real-time imaging guidance removes lens power and prism effects, and the edger follows with three-step clamping pressure and polishing on a bevel or flat edge. One scanner can serve two main machines. The edger measures 625 × 510 × 510 mm.
