Leica DM1000 LED Start-up Adjusting the Light Sources, Never look directly into the beam path

7. Start-up

7.4 Adjusting the Light Sources

Centering is only required when using the 106z* lamp housing.

• When a supply unit is used, it is turned on first

Caution!

Never look directly into the beam path!

Caution!

Light sources pose a potential irradiation risk (glare, UV-radiation, IR-radiation).

For the 106z lamp housing, the direct arc image (for gas discharge lamps) and its mirror image are focused separately and adjusted to each other.

•Move the filter system* or reflector* into the light path

•Open the shutter and remove any diffusing screens* from the light path

•Put a piece of paper on the specimen stage and roughly focus the surface with a dry objective of low to medium magnification

•Set the field and aperture diaphragms roughly at the center position

•With a felt or ballpoint pen, make a marking at any position on the paper and slide it into the small illuminated field

•Turn a vacant nosepiece position into the light path or remove the objective

The light source will then be imaged onto the paper. While observing the light source, the lamp is adjusted as follows.
