NIDEK
The NIDEK LM-1800PD/1800P automatic lensmeter delivers high-precision results using a Hartmann sensor with 108 measurement points. It ensures accurate and repeatable data even for complex multifocal lenses. The system incorporates green light transmittance measurement for optical clarity assessment and ultraviolet (UV) transmittance measurement to evaluate lens protection performance. A 5.7-inch color LCD touchscreen with tilting display provides excellent visibility and ergonomic operation. Key functions include PD (pupillary distance) measurement, a built-in Eye Care Card system, and refractive index calculation, ensuring comprehensive optical data analysis. The integrated high-speed linear printer with an automatic cutter enables instant result printing, while the enhanced user interface and optimized data processing make the LM-1800PD/1800P an advanced and efficient solution for modern optical practices.
Detailed information
Hartmann Sensor with 108 multiple measurement points
An advanced measurement principle, that incorporates simultaneous measurement of 108 data points within the nosepiece, provides greater accuracy and reliability with easier and faster measurements.
Unique lens table expanding measurement range
A unique mechanism of the lens table allows the nosepiece to partially enter into the lens table. The mechanical change enables easy measurement of near portion of progressive lens without taking the lens table off, even though the near portion is located on the edge of the frame.
Distortion check
This function shows the lens distortion of glasses used by customers. It compares the vertex power of peripheral eight portions with the power of center portion in the nosepiece aperture. The degrees of deviation from ISO standards at the peripheral eight portions are displayed by colors.
Green light / UV transmittance measurement
The LM-1800PD/1800P can measure the transmittance of visible light by using the green light source. This function digitally calculates the transmittance through tinted lenses such as sunglasses, which has been estimated only on feel until now. It can also measure UV transmittance in the range of 0 to 100% by 1 or 5% increments. The comparison of the two lenses can be easily displayed.
