APPENDIX A: OPTICAL

HOW TO READ THE OPTICAL CHARTS

The optical charts indicate the nominal target spot diameter at various distances from

the sensing head. Information on the top line of each chart shows the different spot

diameters at the distances from the sensor given on the bottom line (see Figure A-1).

All measurements are in millimeters or meters and inches.

Model

Type

Focus Point D:S = Distance to spot divided by spot diameter at the focus point

Far Field D:S = Ratio at distances greater than 10x the focus distance

How to calculate spot sizes

To calculate a spot size between two

known points on an optical chart, use

the following formula:

Sx = Sn + x (Sf - Sn)

Sx = Unknown spot size

Sn = Smaller known spot size

Sf = Larger known spot size

Dx = Distance to unknown spot

Dn = Distance to smaller known spot

Df = Distance to larger known spot

(Dx - Dn)

(Df - Dn)
