Upon initialization the AL-200 will display the Reichert logo screen and perform a brief calibration check. After the calibration is complete, press any button to enter Single Vision Auto Measurement mode.

Note: Do not place any lenses or obstructions in front of the aperture during calibration.

 

 

 

 

The AL-200’s default measurement mode is Single Vision, Automatic. This mode is used for fast, easy measurement of a pair of single vision spectacle lenses. The instrument is now ready to measure the right lens, indicated by the highlighted R on the upper left side of the screen.

 

 

 

 

Place the spectacles on the lens table and secure the right lens with the lens holder. Using the table base levers and your hand, move the lens until the large cross is positioned directly over the small cross in the middle of the centering target. If the operator inserts a progressive lens in single vision mode, the progressive icon may flash to indicate that the mode should be changed.

 

 

 

When optical center has been located, the AL-200 tone will sound and the measurements will be locked on the screen. Upon removal of the lens the AL-200 will automatically switch to the left lens, indicated by the highlighted L on the upper right side of the screen. Repeat the measurement process for the left lens. All measurements will remain on the screen until the operator chooses to print or clear the data.

 

Upon initialization the AL-200 will display the Reichert logo screen and perform a brief calibration check. After the calibration is complete, press any button to continue.

Note: Do not place any lenses or obstruc- tions in front of the aperture during calibration.

To switch to Auto Progressive mode, simply press the lens type button once.

 

 

 

 

Once in Auto Progressive mode the AL-200 is ready to measure the right lens of a pair of progressive spectacles, indicated by the highlighted R in the upper left corner of the screen.

 

 

 

 

To measure the distance segment of the lens, place the spectacles on the lens table and secure the right lens with the lens holder. Using the table base levers and your hand, move the lens until the large cross is positioned directly over the small cross in the middle of the centering target.

 

 

 

When the lens has been properly positioned, the AL-200 tone will sound and the distance measurement will be locked on the screen. An arrow will appear on the screen instructing the operator to move the lens upward to begin measuring the progressive zone (add).

Note: The design of certain progressive lenses may prohibit auto distance measurement. In these cases operators must press the hold button to lock the distance value on the screen.

 

 

As the lens is moved through the add zone, black lines will fill the progressive area on the screen indicating the amount of add being detected. In addition, the add power (in diopters) is displayed at the bottom corner of the screen.

 

 

 

 

Arrows to the right and left of the add zone will indicate if the operator is moving outside the progressive zone. Continue following the direction of the arrows until the maximum add power is reached.

Note: The black lines may not completely fill the progressive area.

 

 

 

To lock the add power on the screen the oper- ator simply presses the hold button on the top of the AL200. The tone will sound and all right lens measurement values will be locked on the screen. Upon removal of the lens the AL200 will automatically switch to the left lens, indi- cated by the highlighted L on the upper right side of the screen. Repeat the measurement process for the left lens. All measurements will remain on the screen until the operator chooses to print or clear the data.

Upon initialization the AL-200 will display the Reichert logo screen and perform a brief calibration check. After the calibration is com- plete, press any button to continue.

Note: Do not place any lenses or obstruc- tions in front of the aperture during calibration.

To switch to Auto Bifocal mode, simply press the lens type button twice.

 

 

 

Once in Auto Bifocal mode the AL-200 is ready to measure the right lens of a pair of bifocal spectacles, indicated by the highlighted R in the upper left corner of the screen.

 

 

 

 

To measure the distance segment of the lens, place the spectacles on the lens table and secure the right lens with the lens holder. Using the table base levers and your hand, move the lens until the large cross is positioned directly over the small cross in the middle of the centering target.

 

 

 

 

When the lens is properly positioned, the AL-200 tone will sound and the distance measurements will be locked on the screen. An arrow will appear on the screen instructing the operator to move the lens to measure the add power.

 

 

 

 

Move the lens to position the add power segment over the aperture. The AL-200 will automatically detect the add power and lock the value on the screen. Upon removal of the lens the AL200 will automatically switch to the left lens, indicated by the highlighted L on the upper right side of the screen. Repeat the measurement process for the left lens. All measurements will remain on the screen until the operator chooses to print or clear the data.

Upon initialization the AL-200 will display the Reichert logo screen and perform a brief calibration check. After the calibration is complete, press any button to continue.

Note: Do not place any lenses or obstructions in front of the aperture during calibration.

To switch to Single Vision Manual mode, simply press the Auto/Manual button.

 

 

 

Once in Single Vision Manual mode the AL-200 is ready to measure the right lens of a pair of single vision spectacles, indicated by the highlighted R in the upper left corner of the screen. If preferred, the left lens can be measured firstby pressing the Right/Left lens button.

 

 

 

 

Place the spectacles on the lens table and secure the right lens with the lens holder. Using the table base levers and your hand, move the lens until the large cross is positioned directly over the small cross in the middle of the centering target. If the operator inserts a progressive lens in single vision mode, the progressive icon may flash to indicate that the mode should be changed.

 

 

 

Press the hold button when the desired positioning has been reached. The AL-200 tone will sound and measurements will be locked on the screen. Remove the lens and press the Right/Left lens button to measure the next lens. Repeat the measurement process for the left lens. All measurements will remain on the screen until the operator chooses to print or clear the data.

Upon initialization the AL-200 will display the Reichert logo screen and perform a brief calibration check. After the calibration is complete, press any button to continue.

Note: Do not place any lenses or obstructions in front of the aperture during calibration.

To switch to Progressive mode, simply press the lens type button once, then press the A/M button to enter manual mode

 

 

 

Once in Progressive Manual mode the AL-200 is ready to measure the right lens of a pair of progressive spectacles, indicated by the highlighted R on the upper left side of the screen. If preferred, the left lens can be measured first by pressing the Right /Left lens button.

Marked Lens

Prism measurements for a marked lens are obtained by measuring at the indicated measurement point on the lens.

Unmarked Lens

Prism measurements in an unmarked lens are obtained by:
• First applying a non-permanent ink dot on the lens where the patient’s distance vision is focused (aligned with the center of the pupil). If an add segment is present, a second dot may be applied to facilitate the add reading
• Prism (and Sphere, Cylinder, and Axis) measurements are obtained by measuring at the ink dot on the lens.

Note: Measurements for prism are displayed in either the x-y (x, y displacement in mm), or P-b (prism in diopters) as indicated in the SETUP mode (Prism option).

Note: If a lens is not marked with the optical center, an inaccurate prism measure- ment may be displayed.
