| Common features among all the models such
as 1LM21, VL2000 series, HD and OPTELICS® are 1) observation and measurement can
be easily performed under ordinary atmosphere, 2) real time observation is available,
and 3) measurable with sub-micron accuracy. There are following application examples
taking advantage of the features mentioned above. |
 |
|
|
| 1. Observation and measurements of dental cement
and such |
It is a common concept that observation of materials
that are used in mouth cavity by SEM is very difficult because these materials
contain remarkable amount of water. The Wide view type confocal microscope is
favorably accepted because it provides easy observations of materials in ordinary
atmosphere without any processes such as vapor deposition and so on.

|
| 2. Observation and measurements of cosmic dusts |
| “Cannot be hewed out” samples such as
a space shuttle can be observed and measured by the small head type 1LM21P, for
example, micro craters generated on a space shuttle by collision of “cosmic
dust” can be measured. Observations and measurements can be performed on
those precious samples that are very large and in addition cannot be cut out.
This is a very useful example of effective applications for the portable confocal
microscope. |

|
|
| 3. Observation under high temperature heating |
In the field of new materials, development of highly
stable and high strength materials is progressing day by day. To study the damage
on materials by heat is part of the material development. The laser microscope
enables real time observation of the material in detail while heating a sample
at the maximum temperature of 1750 degrees centigrade.
This is an observation example fully utilizing the strong point of the laser microscope
that does not miss even the smallest change in the sample with its real time and
high resolution observation capability. |

|
|
| 4. Observation of food |
| The confocal microscope enables easy observation of
food that contains a lot of oil or water. Frozen food and such can be observed
in the frozen state by installing cooling machine. In addition, chocolate that
is easy to melt can be observed without melting due to low output power of laser
light for observation. |
|
|
|
| 5. Management of printing drum |
| Printing drums that produces vast amount of printed
materials every day are consumable articles. In an unlikely event that a worn
away drum were operated in such state, defective materials would be produced in
great mass and this would become a great loss as a result. Even under such circumstance,
1LM21P portable type will securely check out the extent of wearing out and drum
replacement timing would be correctly reported. |
|
|
|
| 6. Observation of transparent polymer crystals |
| Confocal microscopes are widely used in the field
of polymer materials. Function that provides easy observation in an ordinary atmosphere
with high resolution is very useful for new polymer development. |
|
|
|
| 7. Observation and measurements of printer head |
| Pinter heads of Ink Jet Printers and such are equipped
with colored transparent film of each color of Cyan, Magenta, or Yellow, on the
multi nozzles and there are cases that either these transparent films can be observed
or that these transparent films cannot be observed, depending on the wavelength
of the light source in a microscope. This phenomenon is due to the wavelength
dependence of transmittance for each film. However, by using OPTELICS® that enables
wavelength selection, observation and measurements of these films can be easily
made not depending on the film color. |
|
|
|
| 8. Observation of Color Filter in LCD |
| Because R, G and B color filters consist of three
elementary colors, confocal measurement by single wavelength is impossible. However,
OPTELICS® that has capability of wavelength selection can perform the measurement. |
|
|
|
| 9. Observation of nano imprint |
| The nano imprint technology that is the next generation
ultra fine processing technology is a technology with enormous potential for various
applications. Possible materials to be applied have wide varieties from glasses
to metals. For verification of manufacturing processes, confocal microscopes that
provide high precision measurements have become indispensable. |
|
|
|
| 10. Measurement of MEMS |
| For quality preservation in micro processing technology,
a confocal microscope with a capability to automatically perform measurement by
a special software is best suited. After speedily performing measurements on patterns,
line widths and height, the result is output in format. This type of function
is only possible because of the very fast scan speed that Lasertec can realize. |
|
|
|
| 11. Analyses of materials |
| By combining with a laser Raman Spectroscope (option),
not only shape measurement but also material analysis and stress analysis in the
same observation area can be performed, resulting in wide variety of applications.
Chemical composition analysis and physical structural analysis can be carried
out in a nondestructive and speedily way. |
