Chromatic confocal Microscopy (Diavite Optic)

Here we show different application examples of our chromatic-confocal measuring head RB-400-90°, integrated in the Diavite Optic measuring station.

Diavite Optic

An optical RB-400-90°.1 measuring head is integrated in the Diavite Optic measuring system. In addition, tactile comparison measurements can also be performed.

Measurements on the reference standard RUGOTEST 1

RUGO-N8A (Ra 3,2 µm), RUGO-N9A (Ra 6,3 µm), RUGO-N10A (Ra 12,5 µm)

Roll-milled surfaces are primarily one-dimensionally rough and can therefore be compared well via profile sections.

Comparison of optical measurements (blue profiles) and tactile comparison measurements (green profiles) on three roll-milled surfaces.


RUGO-N6B (Ra 0,8 µm)

Face-milled surfaces tend to be two-dimensionally rough and therefore require an areal measurement (left image).

In the right image, two optical profiles P1 (blue) and P2 (black) are extracted from the areal measurement. For comparison, a tactile profile T (green) is also shown.


RUGO-N7B (Ra 1,6 µm)

Face-milled surfaces tend to be two-dimensionally rough and therefore require an areal measurement (left image).

In the right image, two optical profiles P1 (blue) and P2 (black) are extracted from the areal measurement. For comparison, a tactile profile T (green) is also shown.


RUGO-N8B (Ra 3,2 µm)

Face-milled surfaces tend to be two-dimensionally rough and therefore require an areal measurement (left image).

In the right image, two optical profiles P1 (blue) and P2 (black) are extracted from the areal measurement. For comparison, a tactile profile T (green) is also shown.


RUGO-N9B (Ra 6,3 µm)

Face-milled surfaces tend to be two-dimensionally rough and therefore require an areal measurement (left image).

In the right image, two optical profiles P1 (blue) and P2 (black) are extracted from the areal measurement. For comparison, a tactile profile T (green) is also shown.


RUGO-N10B (Ra 12,5 µm)

Face-milled surfaces tend to be two-dimensionally rough and therefore require an areal measurement (left image).

In the right image, two optical profiles P1 (blue) and P2 (black) are extracted from the areal measurement. For comparison, a tactile profile T (green) is also shown.


RUGO-N6C (Ra 0,8 µm), RUGO-N7C (Ra 1,6 µm), RUGO-N8C (Ra 3,2 µm)

Planed / turned surfaces are primarily one-dimensional rough and can therefore be compared well via profile sections.

RUGO-N9C (Ra 6,3 µm), RUGO-N10C (Ra 12,5 µm)

Planed / turned surfaces are primarily one-dimensional rough and can therefore be compared well via profile sections.

Comparison of optical measurements (blue profiles) and tactile comparison measurements (green profiles) on two planed / turned surfaces.


RUGO-N6A (Ra 0,8 µm), RUGO-N7A (Ra 1,6 µm)

Although ground surfaces are rough in two dimensions, they usually do not show any superimposed texture. Therefore, they can be compared well via profile sections.
