DPM 100

Dig­i­tal Pocket Micro­s­cope

The NEW DPM 100 Dig­i­tal Pocket Micro­s­cope offers vary­ing mag­ni­fi­ca­tion up to 200x suit­able for most qual­ity inspec­tion work. The micro­s­cope fea­tures inte­grated LED illu­mi­na­tion which can be turned on and off depend­ing on the appli­ca­tion. The DPM con­tains a high-res­o­lu­tion color cam­era which pro­vides crisp, clear images. To cap­ture an image sim­ply press the red but­ton on the micro­s­cope. The micro­s­cope can be used for many appli­ca­tions, such as print qual­ity, paper struc­ture, coat­ings, tex­tiles, plas­tics, etc.

Typ­i­cal Appli­ca­tion

Print and Paper Indus­try

Dots & Satel­lites
The "Dot" func­tion deter­mines the num­ber of dots, aver­age area size (mm²) and their cov­ered area (%) together with the cor­re­spond­ing data for detected satel­lites inside the defined region.

Lines
The "Line" func­tion will auto­mat­i­cally char­ac­ter­ize the lead­ing and trail­ing edges of the line with respect to the angle, blur­ri­ness, ragged­ness together with the width (mm) and con­trast of the line accord­ing to the ISO 13660 spe­c­i­fi­ca­tions.

Shapes
The "Shape" func­tion will auto­mat­i­cally char­ac­ter­ize the area (mm²), width (mm), height (mm) and perime­ter (mm) of the selected object inside the defined region.

Voids
"Voids" are detected when a solid black area has white, unprinted spots in it. The voids must be within the size lim­its defined by the voids param­e­ter. The DPM soft­ware will count the num­ber of detected voids inside the selected area.

Mottling & Graini­ness
This func­tion char­ac­ter­izes how evenly a uni­form printed area appears to the human eye.
For "Graini­ness", the high fre­quency vari­a­tions are char­ac­ter­ized from sub-images (tiles) of dif­fer­ent sizes from 0.042 mm (0.0018 mm²) up to 1.02 mm where the smaller tiles will divide the defined region into more sub-images (counts). The vari­a­tion between the sub-images of a par­tic­u­lar grid size (Grid) is then cal­cu­lated as the stan­dard devi­a­tion (S.D). Finally the dif­fer­ent stan­dard devi­a­tions are aver­aged into one sin­gle "Total" num­ber.

The "Mottling" describes the low fre­quency pat­tern and here only a sin­gle grid size of 1.27 mm is used to cal­cu­late the vari­a­tion. Accord­ing to ISO 13660, the region must be at least 161 mm² (12.7 mm x 12.7 mm) in which case the DPM instru­ment must be ins­talled on a stand to obtain 100 tiles for mottling.

Paint and Coat­ing Indus­try

Destruc­tive Film Thick­ness
The V-shaped cut from the byko-cut can be eas­ily stored as an image with film thick­ness info in mm. Also the width from the cut can be detected and recal­cu­lated to the film thick­ness of the coat­ing depend­ing on the cut-Angle.

Adh­e­sion Test
Eval­u­a­tion of the adh­e­sion of a coat­ing. Store the image into the DPM Soft­ware database and view the cross-cut on the screen and eval­u­ate the edges, lines, shapes and defects of the cross-cut image.

Buch­holz Inden­ta­tion
The inden­ta­tion test as per Buch­holz is a reli­able test method for eval­u­a­tion of inden­ta­tion resis­tance of plas­tic deformable coat­ings. Eval­u­ate the length after the test with the func­tion "Dis­tance Tool" and con­vert the val­ues with the "Buch­holz Inden­ta­tion Table".
