Hard-core strength foresight
Simple design | Laser measurement system | Ultra-high resolution
It combines industrial aesthetics, innovative design and flagship performance, breaking through the industry’s inherent impression of ophthalmometers, creating an objective ophthalmometer solution with advanced concepts and comprehensive functions, making the measurement results more accurate and stable.
Features:
Near-infrared laser measurement technology
The near-infrared laser light source is used for measurement, which has concentrated energy and can produce a stable projected image, and can easily cope with human eye measurement under various complex conditions.
NIR band enhanced sensor
Equipped with SONYONIR band enhanced sensor, it can provide >90% QE in the range of 700-850nm, and improve the overall signal-to-noise ratio by reducing transient noise, thereby improving the accuracy and repeatability of measurement.
Imported high performance stepper motor
It adopts open-loop subdivision control of a two-phase hybrid stepping motor, with low motion resistance and high positioning accuracy. After 320,000 endurance operation tests, the movement is still smooth.
7-inch fully laminated touch screen
1024×600 resolution, supports 5°–80° tilt adjustment, and is equipped with a full lamination process to reduce the thickness of the air layer between the display and the touch layer, eliminate reflection and scattering, reduce image distortion, and have obvious advantages in brightness adaptability, contrast, life and maintainability.
Supports corneal peripheral curvature and eccentricity measurement
Eccentricity is the rate at which the refractive power of the cornea flattens from the center to the periphery. This indicator is used to describe the degree of asphericity of the corneal surface. Measuring eccentricity can help doctors quickly assess the health of the cornea, especially for some corneal diseases such as corneal deformity and corneal degeneration.
Global Image Stack Technology
The entire imaging area has an excellent resolution of more than 20LP/mm, presenting clear and sharp images from the center to the edge of the picture. It combines WDR wide dynamic technology and multi-frame fusion imaging to create excellent image quality, with deep and sharp transitions between light and dark, and every detail of the cornea is clearly visible.
Real-time eye height indicator
The progress bars on both sides of the measurement interface respectively indicate the total stroke of the jaw rest/Z-axis motor and the current dwell position. When the human eye is not within the field of view, the progress bar can be used to intuitively determine the direction in which the jaw rest and measurement window need to be adjusted, which is convenient and quick.
Optometry room hub linkage strategy
Through the USB and RS-232 interfaces, it can be networked with the YPA-2100 automatic optometry head control terminal in wired or external wireless mode. The configuration and data of sub-devices can be centrally managed through the tablet, realizing intelligent linkage between products and cross-device operation, and completing the optometry process quickly and efficiently.
