Product Overview
  • Key Features

    • Higher loads and wider applications make iMicro the only choice for serious research labs around the world.
    • Allows for a wide range of tests including, but not limited to frequency specific experiments, storage and loss modulus, modulus and hardness (Oliver and Pharr) and constant strain rate.
    • Mulitple actuator options available for testing any material from ultra soft gels to hard coatings.
    • Available scratch option featuring a maximum normal load of 50 mN, maximum scratch distance of 2.5mm and a maximum scratch speed of 500 µm/s.

    Product Description

    Electromagnetic actuators are used in all systems produced by KLA, including the iMicro. These actuators are robust linear devices that inherently decouple force and displacement. They offer a maximum force of 1N, resolution of 6 nN and ultra low noise floors of less < 200 nN.

    With a time constant of 20 micro seconds, the iMicro is the only commercial nanoindenter to simultaneously meet specs for a maximum indenter travel of 80 µm, a noise floor of < 0.1 nm, a digital resolution of 0.04 nm and drift rates of < 0.05 nm/s.

    To ensure the widest range and most reliable data in the industry, iMicro is capable of dynamic excitation frequencies from 0.1 Hz to 1 kHz.

    iMicro includes InView software, which offers an extremely powerful and intuitive experiment-scripting platform that can be used for designing novel experiments. Experienced users can set up and perform virtually any small-scale mechanical test with the iMicro.

    Sample stage movement of 25 mm in the Z axis, 100 mm in the X, and 100 mm in the Y axis allows testing of a wide range of sample heights, and over a large sample area.

    Load-frame stiffness > 3,500,000 N/m

    Unique tip-calibration system integrated into the software that allows for fast, accurate and automated tip calibration

    Optional NanoBlitz Topography and Tomography Software to perform 3D and 4D mapping of materials.
