LM-1800P Auto Lensmeter: Advanced Hartmann Sensor, Accurate Lens Measurement, and Enhanced Usability Features
The LM-1800P Auto Lensmeter is an advanced lens measurement tool that uses the Hartmann sensor with 108 multiple measurement points. This innovative measurement principle allows simultaneous data collection from 108 points within the nosepiece, providing greater accuracy and reliability. This advanced method facilitates and speeds up measurements, making the process more efficient and less prone to errors.
One of the highlighted features of the LM-1800P Auto Lensmeter is distortion check. This function shows the lens distortion of glasses used by customers, comparing the vertex power of eight peripheral portions with the power of the central portion in the nosepiece aperture. Deviations from ISO standards in the peripheral portions are displayed in colors, allowing a clear visualization of discrepancies. It is important to note that the results serve only as a guide since the entire lens distortion distribution cannot be measured.
Another important feature of the LM-1800P is the ability to measure visible light transmittance using a green light source. This function digitally calculates the transmittance through tinted lenses, such as sunglasses, which previously were estimated only visually. This enables recommending sunglasses with quantitative color strength based on visible light transmittance. It is important to note that the results of green light transmittance measurements should be used only as a reference, as in-house data showed a correlation between these results and luminous transmittance.
Placing the lens on the nosepiece activates the auto lens detection function, automatically determining the lens type and switching to the correct measuring mode. This functionality not only simplifies the measurement process but also ensures that measurements are performed correctly, regardless of the lens type.
The use of green measurement light, which is close to the ISO standard, results in more precise measurement values without the need for Abbe number compensation. This means that the measurement results are more reliable and better reflect the actual properties of the lenses, providing greater confidence in the obtained data.
The LM-1800P Auto Lensmeter also boasts a unique lens table mechanism that expands the measurement range. This innovative design allows the nosepiece to partially enter the lens table, enabling the easy measurement of the near portion of progressive lenses without having to remove the lens table, even if the near portion is located on the edge of the frame. This feature simplifies the process and enhances the versatility of the device.
Additionally, the prism layout function allows for easy marking of lenses at the prism prescription position. By entering the prism prescription value in advance, users can simply follow the target displayed on the screen to accurately mark the lenses, streamlining the workflow and improving precision.
The device includes improved marking ink, which provides clear dots even on lenses with a water repellent coating or finish. This enhancement ensures that markings are visible and durable, regardless of the lens surface treatment.
Moreover, the LM-1800P Auto Lensmeter features UV measurements with a visually enhanced display. This function shows UV transmittance in the range of 0 to 100%, with increments of 1% or 5%. This allows for easy comparison of UV protection between two lenses, offering a comprehensive understanding of their performance.
The device is also equipped with a high-speed printer that produces easy-to-read printouts. Measurement data is presented in a clear and logical manner, facilitating straightforward explanations to customers. This combination of advanced features makes the LM-1800P Auto Lensmeter an invaluable tool for professionals seeking accurate, efficient, and comprehensive lens measurements.
The LM-1800P Auto Lensmeter features a 5.7-inch color LCD touch screen, which enhances the user experience with its ideal layout display. This touch screen is superior in both operation and visibility, making it easier for users to navigate and perform measurements efficiently.
To further improve usability, the lensmeter includes a tiltable (30º) full-graphic LCD monitor. This design provides easier operation for both standing and sitting operators, ensuring comfort and convenience regardless of the working position.
The device also incorporates a card slot for the Eye Care card system, allowing for quick and easy wireless data transfer with auto refractometers and digital refractors. This feature streamlines the workflow by facilitating seamless integration with other eye care devices.
In terms of connectivity, the LM-1800P Auto Lensmeter comes with a standard LAN connection, in addition to conventional RS-232C and USB connections. This enables direct access to auto refractometers, digital refractors, and computers, ensuring versatile and reliable data management across various devices.
These features collectively make the LM-1800P Auto Lensmeter a user-friendly, efficient, and highly integrated tool for eye care professionals, providing advanced functionalities to support precise and comprehensive lens measurements.
