3D Optical Profiler, Laser Confocal Microscopes
OLS5500

3D Optical Profiler

Exceptional measurement accuracy and Optical performance
OLS5500 hybrid 3D optical profilometer unites laser scanning microscopy (LSM), white light interferometry (WLI), and focus variation microscopy (FVM) in one powerful platform.

Designed for R&D, QA, and QC teams, it delivers precise surface detail, traceable accuracy for confident measurements, and an intuitive user experience to streamline workflows.

Trusted data—powered by precision optics, verifiable calibration, and smart automation—helps labs move seamlessly from first discovery to final decision.
The Complete Solution - FVM, WLI, LSM

Infinite Surfaces, Trusted Results

The award-winning LEXT™ OLS5500 enables you to identify subtle features and surface variations with unparalleled clarity—use LSM, WLI, and FVM to detect defects, confirm designs, and make confident decisions
WLI interferometric lens

White Light Interferometric Objectives

Ideal for smooth and sloped surfaces, the system measures nanometer-scale steps with reliable constant-height performance at any objective magnification.

Laser DIC Clarity

Clarity on Challenging Samples

4K imaging, a top-surface detection filter, laser DIC, dual pinhole optics, and a high-sensitivity sensor work together to deliver exceptional clarity, contrast, and color fidelity—even on the most challenging samples.

Maximized Throughput

WLI improves throughput up to 42×

The OLS5500’s WLI improves throughput by up to 42 times compared to
conventional LSM. Measure nanometer-scale surface textures—traditionally
visible only at the high magnifications of an LSM—without being limited by
objective magnification.

Guaranteed Measurement Accuracy

LEXT microscope objectives deliver highly accurate measurement data. Paired with the Smart Lens Advisor, you can acquire accurate data you can be confident in.

  • Guaranteed measurement accuracy
  • 10x to 100x objectives that reduce aberrations at 405 nm to capture the correct shape of your sample throughout the entire field of view
  • Smart Lens Advisor helps you choose the right objective lens for your roughness measurement

    Laser Confocal Optics

    The laser confocal optical system receives only the light focused through the circular pinhole, rather than capturing all the light reflected and scattered from the sample. This helps eliminate blur, making it possible to acquire an image with higher contrast than can be obtained with an ordinary microscope.

    405 nm Laser Light Source

    A laser microscope using a short-wavelength laser has better lateral resolution than a traditional microscope using visible laser light (peak value 550 nm). The OLS5100 microscope’s 405 nm laser diode offers exceptional lateral resolution.

    Non-contact, nondestructive, and fast
    No sample preparation required—simply place the sample on the stage and you're ready to measure.
    Sub-micron 3D observation/measurement

    Observe steps in the nanometer range and measure height differences at the sub-micron level.

    ISO25178-compliant surface roughness measurement
    Measure surface roughness from linear to planar
    Smart Automation

    Smart Automation for Effortless Precision

    The OLS5500’s smart automation and workflow tools are designed to make surface analysis easier and faster for users of all levels. With Tilt Adjustment Assistance, tilt correction becomes simple. With one click, the software indicates the exact amount of adjustment needed to level the sample surface.

    Smart Data

    Smart Data Detection

    Smart Judge automatically detects only reliable data, delivering accurate measurements without losing fine height irregularity data.
