DataMan 280 Reading Distances and Field of View

This section discusses the Field of View values for 6.2 mm and 16 mm lenses.

6.2 mm lenses can be focused to 105 mm (short range) and to 190 mm (long range).

The following tables show the Field of View (FoV) widths of the 6.2 mm lens focused to 190 mm at various distances:

Working distance in mm	Horizontal values in mm	Vertical values in mm
Z1= 190	X1= 159	Y1= 119
Z2= 225	X2= 187	Y2= 140
Z3 = 375	X3 = 307	Y3 = 230
Z4 = 1000	X4 = 808	Y4 = 606

150	10	6
190	12	8
225	15	8
375	20	15
