Shin Nippon DR 900

An interface Desigh Realizing Smooth Communication and Superb Operability

Speedy, Smooth & Silent
High quality and ultra-reliable optical parts allow faster, smoother and quieter measurement through the high-precision mechanism design, featuring a sequential-control lens rotating unit. This refractor is based on a human-interface design, prioritizing user-friendliness e.g. by focusing on operation "noise".

Smart & Slim
The head unit incorporates all required optical functions as well as enabling a smart, slim and compact design. Smooth and comfortable measurement is possible without exposing patients to any feeling of pressure.
High-speed Silent Head
With a high-precision optical mechanism installed in the head unit. Achieving unrivalled speed and smooth and noiseless motion, lets you measure patients instantly without tiring them out.
Hi-Speed UV measurement
Wide Field of View
The head unit was designed to be as slim as possible,
based on the layout and tuning of the lens unit
and retaining the lens diameter. This achieves abrighter
and wider field of view (40°).
Hi-Speed UV measurement
Sophisticated detail and quality. A stylish form and color that match
various spaces.Classy two-tone metallic & pearl coating, combined
with a sharp design, which also features smooth curves, reflects
its high quality and reliability for users.

Simply & Easy Operation
facilitate “intuitive” use for the operator and offer various measurement methods,
the touch panel input and jog dial/button (keyboard) input are divided.
Flexible and free operation via parallel input is also available.
A large touch panel with good visibility and simple, easily selectable touch buttons
allow easy and "intuitive" operation without a manual by adding operating "sounds".
Hi-Speed UV measurement
Jog Dial/Operation Buttons
A jog dial integrating a dial and Enter key allows the direct
selection of "Select", "Adjust" and "Enter" functions.
The jog dial/buttons have shapes and touch that enable touch typing
and focus on the operational feeling in every detail.

Compact Body/Printer with an automatic cutter
The printer is placed on a rear surface to enable a compact and space-saving design. Paper is easily replaced by inserting new rolls into the printer.
Hi-Speed UV measurement
Free measurement position
The touch panel can be tiltted up to 80 degrees.
You can measure comfortably whether standing
or sitting. The keyboard panel is designed to be slim to avoid interfering with operation.
Hi-Speed UV measurement
Multi Interface Design
The operation screen of the LCD touch panel has a user-friendly layout and color plan and designed to divide the screen into three display areas to organize information. A series of operations from "Setup" → "Measure" → "Display" check can be implemented "intuitively" and "sensuously".
