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.

User-Friendly Tiltable LCD with 5.7-inch Touch Color Panel

A tiltable (30°) full-graphic LCD monitor provides easier operation for both standing and sitting operators. The adoption of the touch screen achieves ideal layout display, superior in operation and visibility.

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 Transmittance Measurement

The LM-1800PD / 1800P is able to 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 enables to recommend sunglasses with quantitative color strength based on the visible light transmittance. Additionally, this function helps to ease the vision difficulty at nighttime due to the aging of a customer using tinted Rx lenses on a daily basis.

Refractive Index Measurement Kit GO-MEISAN (optional)

The LM-1800 series have an application for measuring refractive index of eyeglass lenses which corresponds to the GO-MEISAN system made by TOKAI OPTICAL CO., LTD.
