DPM 200, 300 and 400

Digital Pocket Microscopes

The DPM instruments deliver crisp, clear color images with a resolution up to 1280 x 1024 pixels. The integrated LED illumination can be switched on/off, which allows optional external illumination for special investigations. The touch button on the DPM is pressed to capture an image. With the DPM placed directly upon a surface, the focus wheel has two positions giving different magnification levels. The DPM can also be placed on a distance above the test surface and will then view a larger area.

The DPM standard application software (included) features dimension calibration, background correction and image enhancements. Captured images are stored in a database together with comments, manual measurements (distance, area, angle and radius). Live images may be continually analyzed to provide instant results. All may be exported/imported and printed as reports. The DPM application runs under Windows operating systems XP/Vista/W7/W8 (32/64 bit).

Different modules are used to group functionality. Currently there are three modules, Paint, Print and Textile.



Paint Module Features

  • Buchholz Indentation - Is used to measure the impact of an edge pressed against a painted surface.
  • Cross Cut Adhesion - Determines how well a paint is adhered to a painted surface.
  • Byko-Cut Film Thickness (Tooke Paint Inspection Gage) - Measures the thickness of multiple coating layers.
  • Cupping Test - Determines the elasticity of a painted surface when stretched.
  • Duro-Test Hardness - Is a scratch test of a painted surface.
  • Color Mottle - Shows the spatial variation of a painted area.
  • Color Check (24-bit) - Determines the average color of a selected region.


Textile Module Advanced Features

  • Cleanliness - Determines how clean a soiled textile is after washing.
  • Stain Spreading - Determines the dynamic spreading of a liquid droplet (e.g. oil)
  • Stain Saturation - Reveals how quickly a liquid droplet penetrates through a textile.
  • Abrasion Test - Determines how a textile can withstand rubbing.
  • Color Mottle - Shows the spatial variation of a colored textile.
  • Color Bleeding - Determines the separation of two adjacent colors applied on a textile.
  • Color Check (24-bit) - Determines the average color of a selected region


Print Module Features

  • Dots - Counts dots and satellites, measures average area (mm2), standard deviation of area and percentage of total area.
  • Voids - Counts voids, measures average area (mm2), standard deviation of area. Voids are detected when a solid black area has white, unprinted spots in it.
  • Lines - Lines automatically characterize the Leading and Trailing edges of a line with respect to its Angle, Blurriness and Raggedness together with the Width (mm) and Contrast of the line according to the ISO 13660 specifications.
  • Mottling - Mottling and Graininess characterize how evenly a uniformly printed area appears to the human eye.
  • Shapes - The Shape function will automatically characterize the area (mm2), widths (mm), height (mm) and perimeter (mm) of a selected object inside the defined ROI (region of interest).
  • Missing dots - Determines the number of missing dots in a regular printed pattern.
  • Color - Displays average color in the ROI area.
  • Fusing cracks - Use Fusing cracks to determine the magnitude toner loss in a fold.
  • Color mottle - Mottling is calculated using the grayscale brightness differences of image pixels. Color mottling is calculated using color point distances in a 3D RGB color cube. The cube is dimensioned so that the grayscale running between the black and white corners of the cube is the same as for grayscale mottling.

DPM Models

DPM 200 DPM 200
For the serious precision applications the DPM 200 has a high resolution of 1.3 megapixel and an adjustable magnification of approximately 10 to 70 times as well as 200x. This model also provides the possibility to calibrate the microscope for measurements. Most used model in the industrial field.

This unit is suggested for use with the Print Module
DPM 300 DPM 300
By using a special polarization filter, the DPM 300 is the right choice when working with the high glare materials such as plastics and metals. This model is delivered with three exchangeable caps: an open cap, a closed cap and a cap with polarization filter.

This unit is suggested for use with the Paint & Print Module. The polarization filter is utilized for highly reflective substrates
DPM 400 DPM 400
The DPM 400 has two types of LED lights that are switchable between white and UV light. This model has a filter to filter out the returning UV light so that an image with natural colors can be obtained. Also available without return filter (model 4113T-VW) and in a version with 375 nm LEDs (model 4113T-FV2W).

This unit is suggested for use with the Textile Module
  The suggested modules above is what the models are most suited for, however they will work with the other modules as well.
