Nidek LM 1000P

The LM-1000P fits optometry practices, ophthalmology clinics, optical dispensaries, and lens-finishing benches. An operator places a lens on the holder,d presses the reading button, and the instrument detects the lens type, selects right or left,t and measures addition without further steps. The same holder reads single vision, bifocal, trifocal, progressive, and contact lenses.

A patient's current glasses are measured first, and the readings become the reference for the next examination. At the dispensing stage, the same readings check a finished pair against the order, and prism readings up to 20 prism diopters cover lenses that carry strong prism. The instrument measures pupillary distance automatically, with monocular and binocular values.

Progressive lenses suit the automatic mode switch. The instrument detects variations in objective refraction across the lens and automatically switches to progressive measurement. UV transmittance appears at four levels on the same screen, so a dispenser can show a patient how a lens treats ultraviolet light, and saved results can be compared across lenses. The graphic target and alignment status guide the operator through each placement, and the reading button under the lens holder records the values when the lens sits correctly.

For lens finishing work, the frame support bar holds uncut lenses for alignment and marking. The marker leaves clear dots on coated lenses, and the frame can be used to check lens mounting. The printer records each result in the patient file, and the USB and RS-232C interfaces transfer data to other systems.

108 measuring points read together

The Hartmann sensor captures 108 points in a single reading. The operator places the lens once.

Automatic lens type detection

The system recognises single vision and progressive lenses without a setting. The mode switches by itself.

Prism readable up to 20 prism diopters

The expanded prism range suits lenses with strong prism. Prism appears with the power values.

UV transmittance at four levels

The graphic shows none, low, moderate or high. Saved data can be compared across lenses.

Automatic pupillary distance

Monocular and binocular pupillary distance are measured automatically. The value joins the lens readings.

Marking dots on coated lenses

Newer ink produces clear dots on hydrophobic and water-repellent coatings. Alignment and marking sit in the same unit.

Tilting graphic LCD

The screen tilts 30° and shows values, alignment status and settings. Function keys sit around the screen.

Built-in high-speed printer

Each result prints from the instrument. The printout joins the patient file or the job.

USB and RS-232C data links

Both interfaces carry data to PCs and servers. RS-232C is the standard protocol for Nidek optometric devices.

Hartmann sensor

The sensor reads 108 measurement points. The reading drives lens type detection.

Lens type detection

The instrument automatically detects single vision and progressive lenses. The reading point direction follows for progressive lenses.

Progressive mode switch

Variations in objective refraction trigger the switch—the measurement mode changes without operator input.

Right and left selection

The instrument automatically selects the right or left lens. Additional measurements run automatically as well.

Prism up to 20 prism diopters

The expanded prism range suits lenses with strong prism. Vertex powers and prismatic effects are included.

UV transmittance graphic

Four levels appear on screen. Saved data supports comparison across lenses.

Automatic pupillary distance

The measurement covers monocular and binocular values. The result sits beside the power readings.

Fully graphic LCD

The front display unit shows measured values, alignment status and settings. A 30° tilt serves sitting and standing use.

Function keys around the screen

Keys sit around the display. Each key relates to an item on screen.

Reading button under the lens holder

The button freezes the measured values. The operator keeps the lens in place while pressing.

Lens marker with newer ink

The marker produces clear dots. It suits lenses with hydrophobic and ultra-hydrophobic coatings.

Frame support bar

The bar supports lens alignment and checking of lens mounting in a frame. Glasses without hinges can be measured.

Built-in high-speed printer

The printer prints measured results on roll paper. An ink cartridge feeds the print head.

USB and RS-232C interfaces

Both interfaces transfer data. RS-232C follows the standard protocol for Nidek optometric devices.

Fuse and cleaning supplies

Fuses are T 1 A 250 V or T 0.5 A 250 V. Cleaning uses a blower, an alcohol-moistened cloth, and lens-cleaning paper.

The LM-1000P suits optometry practices, ophthalmology clinics and dispensaries that want an auto lensmeter with UV transmittance, pupillary distance and a printer in one compact unit. The 108-point Hartmann sensor determines the working style: it detects the lens type, selects right or left, and switches to progressive mode automatically, so the operator only places the lens and presses the reading button. Prism up to 20 prism diopters, four-level UV graphics, and a marker for coated lenses extend the measurement, and USB and RS-232C interfaces transfer results. A built-in high-speed printer records each result at the instrument, and the graphic LCD tilts 30° for sitting or standing use.
