Computation: Micrometry

Question 1

ONLY if micrometers are NOT FULLY seen in the FOV

Answer 1

FORMULA 1

Question 2

ONLY if micrometers are FULLY seen in the FOV

Answer 2

FORMULA 2

Question 3

Solve CF: Not fully seen

Stage units: 16
Ocular units: 20

Answer 3

CF = 8 um

Question 4

Unit is the number of S____?

Answer 4

spaces

Question 5

Solve AS: Fully seen

CF: 8 um
Units: 74

Answer 5

AS = 592

(CF x Units) > (8x74)

Question 6

Solve AS

CF: 12. 6 um
Units: 9

Answer 6

AS = 113.4 um

Question 7

Solve AS not fully seen

OM: 8
SM: 10
Units: 48-15

Answer 7

1.CF: sm x 10 / om
= 10(10) / 8
= 12.5 um

2. CF x Units
   Units: 48-15 = 33
   = 12.5 x 33
   = 412.5 um

Question 8

Step 1 : Calculate for the CALIBRATION FACTOR (CF)

Formula 1: not fully seen
Formula 2: fully seen

Answer 8

1. AS = sm x 10 um / om
2. AS = CF x Units

Question 9

Solve AS fully seen

OM: 8
Units: 16

Answer 9

CF = 1000 um / 8
AS = 125 X 8
AS = 1000
