        Buying dioptrimeters for optical laboratory

        No modern ophthalmic consulting-room, optical lab or salon can function without special equipment. A dioptrimeter is one of the necessary ophthalmology devices. The efficiency of service provided by medical establishments depends on the competent choice of this device in many ways.

        Structural peculiarities and intended use

        The device is indispensable for measurements of the main optical parameters and characteristics of spectacle lenses. It also helps to detect the position of the principal meridian of the astigmatic lenses. This is necessary for determining and fixing of its optical center.

        Simply put, the ocular device is used by ophthalmologists to determine the level of vision defects (nearsightedness or farsightedness). The lensometer evaluates the refracting power of spectacle lenses in definite measure units, namely in diopters. The devices help to measure the operating characteristics and the features of bifocal, trifocal, unitary and progressive lenses.

        The optical instrument consists of the following parts:

        1. A microscope.
        2. A cantilever. The lens, which is being checked, is placed on its surface.
        3. A collimator. A device helps to “catch” the light beams.
        4. A telescope.

        Classification

        Ophthalmological devices differ in many parameters, including the prices. Speaking about the method of data output, there exist the following types of devices:

        • projecting;
        • ocular (may be supplemented with internal or external scale of refraction values).

        The lensometers are also subdivided depending on the control methods:

        1. Manual. They help to determine the nominal and optical centers of the lenses; the “base-apex” line of decentralized and prismatic spectacle lenses and the directions of the main sections of astigmatic lenses. Ophthalmologists use this type of equipment to measure the optical parameters of the produced spectacles.
        2. Digital. The instruments round up the measured values to the optimal ratio. They are perfect for control of negative and positive lenses. It is convenient that the specialists do not have to take an active part in the measurement of progressive spectacle lenses characteristics.

        Right choice

        When buying a dioptrimeter one should go by the budget of the medical establishment. The analogue models are cheaper but they are suitable for more experienced optometrists. The automated versions, although more expensive, considerably facilitate the task for the workers as almost all the processes are computerized.

        One more important piece of advice is to focus the models that allow measuring of the lenses, the diameter of which is at least 0.8 cm and the thickness is no less than 0.2 cm.

        Favorable purchase conditions

        When equipping an ophthalmic consulting-room or a laboratory one may consider not only the primary market, but also a purchase of a used device. BiMedis portal presents interesting variants for sale. The sellers, as well as the buyers, can place offers there. We will help to find and buy a functional manual or autodioptrimeter with all the documentation and a warranty, which will pay off in no time.
