4.2 Stand
Three different stands are available for the SMZ-161:
4.2.1 R2GG (Fig.1)
●
New stand with reflector design to reach more homogeneous illumination and lower temperature.
●
The head holder can be moved freely along the vertical post and be removed totally from the stand.
The diameter of the post is 25mm.
●
This stand is installed with built-in transmitted light (halogen 12V/20W) and incident light (halogen
12V/10W)
illuminators.
●
To turn the stand power on, the main switch (located on the left hand side) should be switched to the
“on”
position.
●
A separated power switch for transmitted and incident illumination is located on the right hand side.
Users are able to select transmitted or incident light or both with these two power switches.
●
Light intensity can be adjusted by turning the knob at the bottom of the stand on the right hand side.
This knob governs the light intensity for the transmitted and incident lights.
●
The illuminating angle of the incident light can be adjusted using the screw located behind the
illuminator.
●
Besides the black and the white stage plate, a frosted glass stage plate is provided for transmitted
light. This plate can be secured using the screw at the bottom front of the stand.
4.2.2 R2LED (Fig.1)
●
Basically the same as the
“R2GG”
stand except that a 3W LED is used instead of halogen bulb for
transmitted light and incident light. It delivers almost no heat to the sample and is ideal for biological
and
heat-sensitive
specimen applications.
4.2.3 Plain stand (Fig.2)
●
This industrial stand allows for extreme flexibility in positioning. It includes a heavy base to maintain
good
stability.
4.3 External
Illuminator
4.3.1
All kinds of external illuminators can be used as incident illuminators ranging from simple desk
lamps to specialized ring illuminators.
