    Except the stage which is supply of OEM, they are imitation products, such as products made in foreign countries.
    Please beware of imitations. Purchasing imitations of our product by mistake, may cause the problem that quality, accuracy, and durability are inferior.

  • What’s fine tuning of the sliding action by pre-load adjustment screws?

    Pre-load adjustment screws are the parts with groove on the opposite side of Rack and pinion handle. With using screwdriver, rotates clockwise (right‐handed) to get the gentle sliding action and levorotation (leftt‐handed) gives you quick and smooth sliding action.
    MIRUC’s traditional pre-load adjustment functionality allows fine tuning of the sliding action.

Measure Scope

  • What’s the characteristic and principal use of Measure Scope?

    By simply replacing the eyepiece micrometer (scale glass), the equipment can be applied to a range of uses, such as measurement, inspection, alignment and positioning, etc. Measure scope can be arranged by optical system・sliding holder・stands・illumination devices, etc.
    Featuring a variety of lens types and eyepiece micrometers, can be used as a non-contact measuring microscope. Images can be photographed and stored using commercially available compact digital cameras.

  • Do you manufacture special order Micrometers?

    Yes. MIRUC has already produced over 1,000types of custom ordered micrometers. Micrometers can be custom-produced to the customer’s individual specifications. Please send us drawing or figures. We will do the quotes for that.

  • What’s the difference between scope unit and Lens barrel optics?

    It is the difference in whether the slider moves up and down for swift focus with handle, attached as standard.
    The microscope unit is equipped with a slider as standard. Lens barrel optics unit features only the microscope optical system.
    Please choose depending on your attachment environment, or stands you own.

    ※Attachment and use of a single-lens reflex camera etc. cannot be performed.

  • Do you have long-focus microscope which can be used from the long distance?

    Yes, we have WL-1 type which can observe more than 300mm from the long distance position.
    WL-1 can be focused to a working distance from 300 mm (17.5×). infinity (8×), and its crosshair scale markings are very useful for positioning.
    Combination set WL-1-FR is also very popular.

    Long-focus microscopes

  • Since the measure scope was used around the machines, it got greasy. Would you overhaul the measure scope?

    Yes. Please send your measure scope to us. Then we’ll estimate.
    According to the state and damage condition of the oil immersion of measure scope, expense changes whether replacement parts are required.

  • Why measure scope is the form of the monocular type?

    The monocular type microscope like a measure scope can observe a work superficially. For the measurement, inspection, alignment and positioning with use of eyepiece micrometer (scale glass) can be work exactly without the image of overlapping or blurring.
    Since the binocular microscope can observe a work in three dimensions, it is suitable for the visual examination, but it is unsuitable for the use incorporating an eyepiece micrometer.
    Therefore, measure scope is the monocular type.

  • Image Recognition Lens

    • What’s the characteristic of Image Recognition Lens?

      As a machinery vision lens for device mounting and site image observation, Image Recognition Lens can be used as a system for production lines and inspection. We provide the Image Recognition lens group as 3 phases of quality and price ranges.
      The feature is that you can choose the lens according to specifications and the budget which you needs.

    • What’s the characteristic of Telecentric Lens?

      A special feature of the telecentric lens is that, even if the workpiece is raised or lowered during focus adjustment, the size (magnification) of the image does not change, and the whole of the work face can be photographed from directly in front.
      MIRUC’s MRC series are optimal lens group for the device mounting lenses, ideal for high precision positioning and size measurement, and delivering high resolution with low distortion.
      There are straight and coaxial incident light types for magnification and WD each.

    • What’s the characteristic of TV Macro Lens?

      MIRUC’s TV macro lens product lineup covers 122 models, including lenses for C mounts, thumb cameras, straight and coaxial incident light types.
      Based on the concept of simple and inexpensive, these products can be used as a versatile positioning and visual inspection.

    • What’s the characteristic of Simple image observation lenses?

      By connecting a special C-mount close-up ring adapter (fixed and variable types) to a measure scope objective lens, it can be used as a low cost image observation lens.
      This is an optical product that is ideally suited to operations such as external inspection and process condition supervision, etc., which require reasonable cost more than high precision.

    • Is it possible to attach to every manufacturer’s CCD cameras and USB cameras

      Yes, C-mount cameras or thumb cameras can be attached to any manufacture’s products.

    • How much is the diameter of the lightning insert size (φ) of the coaxial incident light types?

      Lighting insert standard diameter is φ8. For TV Macro Lens, Spec. can be changed to old φ12 as your demand.

    • Air Pit

      • What’s the difference between P type and N/O type?

        P type : Suction when pressed, blocked when released.
        N/O type : Suction when released, blocked when pressed

      • What kind of usage is the short type convenient for?

        The short type fits into the palm of the hand and is ideal for operations where the shutter button is operated by the thumb.
        Moreover, a person with small hands, such as a female operative, prefers it’s “easy-to-use”.

      • Is it necessarily to have DAP- S Vaccume pump set?

        DAP-12S is not necessarily required. Most users provide an air from the piping in a factory.
        In addition, you can use any vacuum pump if you can connect the hose attached to the air pit so that there is no air leakage.
        DAP-12S set is the product with the equipment attached. If you do not have a vacuum pump or a suction source, we recommend to use DAP- S Vaccume pump set.

      • What kind of effect does air volume control screw have?

        For example, suction and release can be made very smooth indeed.
        You can change the air flow rate using the airflow adjustment screw according to the object’s weight and size.
        When you are handling a verylight and very small object, completely loosen the screw to smoothlyrelease the object. When you handle a heavy object, tighten thescrew to increase the suction force of the air pit.

      • Which attachment is best for glass, precious metals, etc, which should not be scratched during adsorption?

        We recommend Teflon standard tip attachments of soft resin material. If the workpiece is larger plane size, a conductive rubber pad type attachment is also recommended.

      • What kind of attachment is optimal for the usage of adsorption / transport of micro electronic components?

        We recommend resin PEEK conductive standard tip attachments which compounded carbon to enhance conductivity.

      • What is the optimal attachment for the usage of heavy and/or wider workpiece?

        We recommend conductive rubber pad attachments or spatula-type attachments.

      • Can we use Air pit for the suction of the work piece to which water or oil adhered?

        When it is not inhalation of a lot of water and oil, it can be used by AP-DLS of “Dust and liquid stocker”
        Since it will become a cause of failure if water and oil enter to a vacuum pump or the source of suction, it is effective, if it stores with dust and liquid stocker and throws away moderately.
        More details can be found here.

        AP-DLS Dust and liquid stockert

      • Is it possible to use multiple air pits by a single DAP- S Vaccume pump, efficiently?

        Yes. Use JT- multi-hose joint, air hoses can be inserted into every port of the vacuum pump and air pit, and up to 5 air pits can be operated simultaneously.
        More details can be found here.


      • Are there any application examples other than industrial use?

        For example, there are used in Pharmaceutical-related companies, a food factory, nailarium, etc.
