ML Aplanat

High magnification and large visual field. Short reading distance.

An aplanatic system for short distance reading. Two aplanatic lenses in combination with the plano surfaces facing outward is the key to the fantastic optical quality. ML Aplanat is similar to ML A2 in its use but have a bigger lens closer to the eye. This demands a little bigger frame to mount the system in.

Because of the high power and magnification and a reading distance shorter than 10 cm, ML Aplanat is intended to use for reading with one eye only.

People with bad sight usually wish for high magnification and a wide visual field. It is not easy to fulfill this wish since high magnification normally means a distortion of the image in the periphery of the visual field. However, the ML Aplanat system solves this problem by dividing the power into two aplanatic lenses. The way in which the lenses are combined allows high magnification and minimal image distortion. As the patient's sight changes, the lenses can easily be replaced with stronger ones. ML Aplanat is a flexible system for monocular use offering high image quality and a wide visual field.

Image quality

The image quality is excellent with a sharp focus from edge to edge. This is achieved by dividing the power into two lenses and turning the plano surfaces towards the eye and the object being looked at. This facilitates reading since the letters move evenly across the retina at a steady pace.

Visual field

The visual field is an essential part of an LV device since it affects orientation, comfort and confidence. One of the main benefits of this close reading system, compared with telescopic systems, is its wide visual field, which is even wider than that of a CCTV used at a distance of 40 centimetres.

Magnification

According to the new ISO-standard, the ML A2 system is measured and marked with the equivalent power. This will give the true power for systems or lenses used on short distances. A +40 system will give a true retinal magnification of 10X for an emetropic person.

Combination of lenses

There are five different powers of lenses in High index mineral (35 mm). Each lens is inscribed with tiny identification marks indicating the power of the lens.

+12 to +36 diopter can be achieved by combining the lenses according to the table.

Corrections

This new system makes it easy to incorporate a cylinder correction. Simply insert a planocylinder lens between the two power lenses. The planocylinder lens presses into the ring without any need for glue.


Monocularly

This system is intended for short reading distances and should only be prescribed for monocular vision.

Design

Since the lenses are made of mineral High index it has been possible to reduce the depth of the ring by 30 percent. This makes it an aesthetically attractive system with enhanced visual field and image quality.

Easy to fit

Fitting an ML Aplanat could not be easier. Thanks to the mounting lens with its special mounting part, the ML Aplanat is as easy to edge as a plano lens. The system presses into the carrier lens with positional precision down to hundredths of a millimetre. No screws or other tools are needed.

Tolerance 

The large size of the ocular lens and the fact that the plano curve faces the eye means that the exact position of the system is not as critical as with other microscopic systems or lenses. The device can therefore easily be used by an elderly person without having to make painstaking adjustments. 

Multicoated 

All lenses are treated with anti reflex coating to produce superb optical quality. 

Filter 

As for all our products, it is possible to insert a filter in ML Aplanat. 

Changing the power

It is easy to put together or change the lenses in the system. To assemble the system, put the lens in position over the housing and press into place. The lens clicks into position and stays in place without the need for screws. The suction cup is used to remove and change a lens. Simply pull out the lens and press in a new one.

Convert to equivalent power

The A planatic system is measured as standard in back vertex power but could easily be converted into equivalent powers. By using the table below the printed powers on the Aplanatic system could be converted into equivalent values.
