00:00:10,156 --> 00:00:12,886
The Olympus STM7 microscope

2
00:00:12,888 --> 00:00:15,480
is designed for
high-accuracy metrology

3
00:00:15,481 --> 00:00:19,505
and precise measurements
in material science.

4
00:00:19,506 --> 00:00:21,286
With a basic configuration,

5
00:00:21,288 --> 00:00:23,915
often known as a
tool maker’s microscope,

6
00:00:23,916 --> 00:00:26,100
an operator can
quickly take measurements

7
00:00:26,101 --> 00:00:30,018
to see variations in
production or tooling wear.

8
00:00:30,020 --> 00:00:33,265
STM7 measuring software can be added

9
00:00:33,266 --> 00:00:36,491
enabling operators to take
complex measurements,

10
00:00:36,493 --> 00:00:38,285
create testing routines,

11
00:00:38,286 --> 00:00:40,833
and efficiently deliver
pass / fail results

12
00:00:40,835 --> 00:00:45,215
for components such as
printed circuit boards and wafers.

13
00:00:45,216 --> 00:00:48,740
The STM7 has a modular design.

14
00:00:48,741 --> 00:00:51,385
Customization for sample size,
lighting,

15
00:00:51,386 --> 00:00:56,780
and motorization can be addressed by
a wide variety of available options.

16
00:00:56,781 --> 00:00:58,916
In a tool maker’s configuration,

17
00:00:58,918 --> 00:01:03,033
operators simply place their
sample on the STM7’s stage

18
00:01:03,035 --> 00:01:06,098
and locate the feature
they wish to measure.

19
00:01:06,100 --> 00:01:08,810
Moving across the feature
to an end point,

20
00:01:08,811 --> 00:01:13,081
the display shows the distance
measured in all 3 axes.

21
00:01:13,083 --> 00:01:15,366
Olympus offers software to enhance

22
00:01:15,368 --> 00:01:18,830
the microscope’s
measuring capabilities.

23
00:01:18,831 --> 00:01:21,563
Using the software’s
edge detection function

24
00:01:21,565 --> 00:01:24,771
can simplify and
speed up measurements.

25
00:01:24,773 --> 00:01:28,126
In this example, the software
detects five points

26
00:01:28,128 --> 00:01:29,951
while the user quickly moves around

27
00:01:29,953 --> 00:01:33,770
the sides of the rectangle
and obtains results.

28
00:01:33,771 --> 00:01:36,498
Additional edge detection
tools are available

29
00:01:36,500 --> 00:01:39,468
including circle edge detection,
which provides

30
00:01:39,470 --> 00:01:44,181
up to 99 data points for
better measurement accuracy.

31
00:01:44,183 --> 00:01:48,473
Manufacturers often create
hundreds of components an hour.

32
00:01:48,475 --> 00:01:51,430
Periodic sample testing
must be regularly performed

33
00:01:51,431 --> 00:01:57,370
to ensure quality.

34
00:01:57,371 --> 00:02:00,213
The software guides users
to each measurement point

35
00:02:00,215 --> 00:02:05,508
to ensure the correct
measurements are taken.

36
00:02:05,510 --> 00:02:07,748
The software compares
measurement results

37
00:02:07,750 --> 00:02:09,681
to known design tolerances

38
00:02:09,683 --> 00:02:12,831
and automatically displays
any failure in red

39
00:02:12,833 --> 00:02:16,318
so users know immediately
if there is an issue.

40
00:02:16,320 --> 00:02:20,046
Stages for the STM7
range from 50×50

41
00:02:20,048 --> 00:02:23,323
to 300×300 mm and support objects

42
00:02:23,325 --> 00:02:25,621
as large as a 12 inch wafer

43
00:02:25,623 --> 00:02:28,835
or a component weighing up to 30 lbs.

44
00:02:28,836 --> 00:02:31,870
Stages can be equipped
with a rotatable stage plate

45
00:02:31,871 --> 00:02:35,641
to simplify measuring
in a single axis.

46
00:02:35,643 --> 00:02:37,633
By utilizing the clutch feature,

47
00:02:37,635 --> 00:02:39,355
the stage can be moved quickly

48
00:02:39,356 --> 00:02:42,186
for greater distance measurements.

49
00:02:42,188 --> 00:02:44,678
The STM7 offers both manual

50
00:02:44,680 --> 00:02:47,205
and motorized height measurement.

51
00:02:47,206 --> 00:02:49,270
To improve reproducibility,

52
00:02:49,271 --> 00:02:53,385
a focus navigator
can be added to the system.

53
00:02:53,386 --> 00:02:54,933
With a motorized frame,

54
00:02:54,935 --> 00:02:58,098
a convenient hand switch
controls all height movement

55
00:02:58,100 --> 00:03:00,303
while the Z-limit option
keeps the objective

56
00:03:00,305 --> 00:03:03,640
lens from hitting the sample.

57
00:03:03,641 --> 00:03:07,841
A laser autofocus can be paired
with the motorized frame.

58
00:03:07,843 --> 00:03:11,198
While moving across the sample
in the X or Y axis,

59
00:03:11,200 --> 00:03:14,221
the laser autofocus controls
the motorized height

60
00:03:14,223 --> 00:03:16,971
to keep the sample in focus.

61
00:03:16,973 --> 00:03:18,691
Integrated LED lighting

62
00:03:18,693 --> 00:03:21,405
supports controls for
Brightfield or Darkfield

63
00:03:21,406 --> 00:03:23,210
reflected light observation,

64
00:03:23,211 --> 00:03:25,275
transmitted light observation,

65
00:03:25,276 --> 00:03:27,880
and the focus navigator option.

66
00:03:27,881 --> 00:03:30,338
For highly reflective surfaces,

67
00:03:30,340 --> 00:03:34,653
users can add a polarizer
and rotatable analyzer.

68
00:03:34,655 --> 00:03:36,546
Adding a DIC Prism

69
00:03:36,548 --> 00:03:41,110
improves the visibility
of minor surface changes.

70
00:03:41,111 --> 00:03:44,323
The Olympus STM7 measuring microscope

71
00:03:44,325 --> 00:03:47,155
is a versatile,
high performance instrument

72
00:03:47,156 --> 00:03:49,956
which provides operators
three-dimensional measurements

73
00:03:49,958 --> 00:03:52,725
with sub-micron precision.

74
00:03:52,726 --> 00:03:55,735
Olympus Application Specialists
and Service Engineers

75
00:03:55,736 --> 00:03:58,148
