Our autofocus algorithms optimize focus across multiple depths and complex surfaces, supporting workflows such as stacking and depth mapping.

The standard MODI system comes with a variety of integrated lighting types (#1) and controls including ring lights, quandrant ring selection, coaxial lighting, darkfield illumination, fluorescence illumination, backlight sources, and scatter light mode. MODI has scan procedures that auto-detect glare and gradients, adjusting lighting to eliminate any bad data.

MODI scanning has a critical modality called “focus stacking” that allows a series of hundreds of photos to be taken at different depths, combining all images into a high quality fully focused image. This is particularly important for samples with heavy topology changes. Single depth results (#4) and focus stacked results (#5) are showcased below.

Along with focus stacking procedures, you can generate depth maps accurate to the Depth of Field (DoF) of the onboard digital microscope. Our Standard configuration microscope has a depth of 0.1mm, allowing depth maps of 100um in accuracy to be generated (#6).

Automatic scan routines with our digital microscope are used to raster across a sample and autofocus for each image. The result is built into a mosaic “superimage” (#1 & #2) that stitches images across the part into one large image, providing high resolution large field pictures.

Our suite of analysis software tools can be used to detect defects and measure features based on customizable morpholgy and spectral filters (#3 & #4). This can be used for example to detect and distinguish Foreign Object Debris (FOD), surface abrasion, scratches, and contamination.

Our Standard configuration includes a Multispectral Module (#1) sensitive to infrared wavelengths. This point sensor is paired with low-noise, high-speed electronics to deliver high quality data. The point is magnified with optics (#2) to provide spatially resolved measurements. Combined with our motion gantry and autofocus, an image is rastered across a sample. This principle applies to the Spectroscopy Plus configuration, using point spectrometers and generate hyperspectral imagery.

The Optical Modifier Tool Exchange uses magnetic coupling to pick up and remove different filters, lenses, diffusers, and other optical modifiers from the filter bay (#3). With bandpass filters, the spectral module can be used for quantitative applications that require discrete multispectral sensing.

To maintain high quality and consistent results, MODI includes onboard calibration targets that provide known reflectance & emissivity. Calibration is automatically measured and maintained to compensate for any dark current drift, thermal drift, and changes in sensitivity.
