Designed for Everyday Efficiency
Busy optical practices need equipment that is both fast and dependable.
The LM-7 has been developed to provide:
- Rapid lens measurements
- Improved dispensing workflow
- Outstanding measurement accuracy
- Easy operation
- Reliable day-to-day performance
Its intelligent automation reduces operator input whilst ensuring consistent, repeatable results.
Key Features
108-Point Hartmann-Shack Sensor
At the heart of the LM-7 is NIDEK’s advanced 108-point Hartmann-Shack sensor.
Benefits include:
- Simultaneous multi-point measurement
- Exceptional measurement accuracy
- Faster readings
- Greater reliability
- Improved progressive lens analysis
Unlike traditional single-point systems, the LM-7 analyses a much larger area of the lens to deliver highly accurate results.
Automatic Lens Type Detection
Simply place the lens on the nosepiece and the LM-7 automatically identifies whether it is:
- Single vision
- Bifocal
- Progressive
The instrument then selects the correct measuring mode automatically.
Benefits include:
- Faster workflow
- Reduced operator input
- Fewer measurement errors
- Improved efficiency
This intelligent automation makes everyday dispensing quicker and easier.
Green LED Measurement System
The LM-7 uses a 540 nm green LED that closely matches the ISO reference wavelength.
Benefits include:
- Greater measurement precision
- Improved consistency
- Reduced chromatic error
- No Abbe number compensation for most lenses
This ensures highly accurate measurements across a wide range of lens materials.
5.7-Inch Colour Touchscreen
The large vertical touchscreen has been designed for speed and simplicity.
Features include:
- Touchscreen operation
- Clear graphical interface
- Excellent visibility
- Customisable display colours
- Intuitive navigation
Operators can switch between light and dark display modes depending on the colour of the marking ink.
Progressive Lens Measurement
The advanced measurement system simplifies progressive lens verification.
Benefits include:
- Automatic progressive detection
- Easy reading point identification
- Faster measurements
- Reduced repositioning
- Improved dispensing accuracy
The LM-7 quickly identifies distance and near reference points without excessive lens movement.
Prism Layout Function
The integrated Prism Layout function assists with accurate lens marking.
Benefits include:
- Easy prism verification
- Accurate blocking positions
- Simplified glazing workflow
- Improved dispensing accuracy
Operators simply follow the on-screen target for accurate prism positioning.
UV Transmittance Measurement
The LM-7 measures UV transmittance at 365 nm.
Benefits include:
- Verify UV protection
- Compare lens performance
- Support patient education
- Demonstrate lens quality
Results are displayed as a clear percentage from 0–100%.
Scale Mode for PD Measurement
The integrated Scale Mode allows easy measurement of:
- Monocular PD
- Binocular PD
- Progressive distance reference positions
This provides additional dispensing functionality without requiring separate equipment.
Flexible Connectivity
The LM-7 supports integration into modern optical practices.
Available connections include:
- USB
- RS-232C
- Optional LAN
- Optional Wireless LAN
These communication options enable seamless integration with NIDEK dispensing and practice management systems.
Compact Contemporary Design
The elegant vertical design occupies minimal bench space whilst maintaining excellent visibility.
Benefits include:
- Compact footprint
- Modern appearance
- Easy cleaning
- Comfortable operation
Its attractive design complements any dispensing area or glazing laboratory.
