Equipment highlights

Beyond the conventional microscope

Captures one image per wavelength, from ultraviolet to near-infrared, in a single instrument.

Configurable

Choose the standard model or only the spectral ranges your application needs. Later upgrades are possible.

Three-axis automation

Integrated with a high-precision CNC system, it handles spectral mapping by area and focus by depth.

BUILD

Enclosed cabinet, integrated electronics

Aluminum-profile structure with smoked glass that isolates the sample from ambient light. Optical column, power supply, LED controller and ventilation sit inside the cabinet, with external connectors for camera, lighting and automation.

HOW IT WORKS

From sample to result in four steps

Three-axis automation platform of the multispectral microscope
  1. Step 1

    Position

    The sample is positioned and autofocus finds the ideal plane.

  2. Step 2

    Capture

    The LEDs light up in sequence and the camera records one image per band.

  3. Step 3

    Map

    The system scans the area in X and Y and assembles the full spectral cube.

  4. Step 4

    Analyze

    Segmentation, intensity maps and export to your own models.

A spectrum in every pixel, and every pixel in focus.

A spectrometer measures the average of the sample. OpenScience’s multispectral microscope measures the chemical response of every point, from ultraviolet to near-infrared, and shows where each difference is.

The problem

Each wavelength focuses at a different height

In a single plane, part of the sample is out of focus and each pixel mixes the signal of its neighbors. The resulting spectrum is not the sample’s.

The solution

Acquisition at several depths

Controlled illumination and a Z sweep. For each pixel, the spectrum is built only from the bands in focus.

The result

Real spectrum and topography in the same image

Hardware and software developed by OpenScience, with integrated chemometrics to classify and quantify.
