Analytical Functions

Rq (Root-Mean-Square (RMS))

Determines the root-mean-square value of roughness corresponding to Ra (see 

Figure 6-3

). 

Rq has the greatest value in optical applications where it is directly related to the optical 
quality of a surface.

Figure 6-3:  Rq Roughness Analytical Function

Rt (Maximum Peak to Valley)

The sum total of the maximum peak and maximum valley measurements of roughness within 
the assessment length (Rt = Rp + Rv) (see 

Figure 6-4

).

Figure 6-4:  Rt Roughness Analytical Parameters

Rv (Maximum Valley)

The lowest point, or the maximum depth of the profile roughness below the mean line, within 
the assessment length (see 

Figure 6-5

).

R

t

 = R

p

 + R

R

t

 is the sum total of the maximum valley and maximum peak of

roughness.
