1. Illumination unit with the tungsten lamp

(C-151)
The tungsten lamp uses the tungsten filament, and it provides bright light with low voltage. The lamp life ends as the tungsten filament evaporates and brightness level lowers.

2. Illumination unit with the halogen lamp

(C-153, SPH-100, SPH-150)
The halogen lamp has a long life with the halogen cycle inside of the lamp and has the feature of higher brightness when compared to tungsten lamps.
However, because of its high brightness, it releases a large amount of heat.
It is used directly as an illumination by collecting light with lens, and also is used as the light source of the light guide illumination unit by using its high brightness.

3. Illumination unit with the LED lamp

(TS-IL-A3, TS-IL-A5, TS-IL-B5, SPL-100A)
LED has a longer life, lower heat emission, and lower power consumption when compared to tungsten lamps and halogen lamps.
There are illumination light sources, which LED is directly used for illumination and which the light guide is used.

4. Illumination unit with the light guide

(LGG-500W, LGG-500WF, LGG-1000SF, LGG-1000WF, LGG-1000RFZ)
There are two types of light guides that use the optical fiber. One uses the metal flexible tubes, which provide easy handling, and another one uses the interlock system, which has moderate hardness and can be fixed after bending.
In addition, the one with the two-way light emitting port, of which oblique lighting from two directions and lighting to the separate position become available.

5. The light guide supporter

(LGH-1, LGH-2)
It supports the LGG model light guide and fixes the illuminating position.
Because it uses the universal arm, the light guide position and direction can be moved and fixed freely.

6. Lens products for light guide

(LGL-30, LGL-50, LGL-70, LGL-100)
It is used to create a spot light with a small diameter by attaching to the end section of LGG mode light guide.
There are four types, depending on the spot light type.

1. When a longer distance is required between the sample and the illumination unit (heat source)

Select the light guide type in order to set the illumination unit, which is a heat source, apart from the sample.
It is also effective to use the lens to collect the light and directly use for illumination when the illumination unit is placed at the distance. However, it is difficult when a position and a freedom degree of the illumination unit are limited.
How to observe the sample:
When the sample is observed from right above the sample, lighting the sample from above is unavailable unless the illumination unit is integrated to the system. If the sample is lighted from any direction other than directly above, the light source can be attached to the microscope used for observing or the optical system. It is also available to use the oblique lighting or the ring lighting that are lighted from the periphery.

2. Requisites for using the illumination unit

Supporter:
A supporter that is used for fixing the illumination or the light guide is necessary.
When the universal arm type holder is used, the light guide position and direction can be moved and fixed freely.
In case of the interlock type light guide, fixing is available. However, there is a possibility that observing becomes difficult if the lighting position is not steady.

3. Light guide illumination unit

By using the light guide illumination unit, SPH-100 or SPH-150, the illumination environment can be freely created by combining the metal flexible tube, which provides easy handling of the light guide, the interlock type light guide, which has moderate hardness and can be fixed after bending, the light guide with the two-way light emitting port, the ring guide, and the light collecting lens.

4. LED illumination unit

By using the LED illumination unit, SPL-100A, the illumination environment can be freely created by combining the metal flexible tube, which provides easy handling of the light guide, the interlock type light guide, which has moderate hardness and can be fixed after bending, the light guide with the two-way light emitting port, the ring guide, and the light collecting lens.
