Stages

Plane stage and mountable object guide

The plane stage is secured to the microscope with 3 screws. The object guide can be mounted to either the right or the left of the plane stage.

3-plate x/y stage

To attach the stage, 3 screw holes first have to be accessed by moving the stage in x/y direc- tion.

Rotary stage and frame insert for coverslips The rotary stage is secured with 3 screws. Move the rotary mount to gain access to all the screw holes. Put the screws in the holes.

n. b. Use washers as well for the holes at the back. Only screw the screws in lightly, as the rotary stage first has to be centred: to do this, insert the centring aid in the rotary stage. Engage the Bertrand lens by turning the knurl and focus with the lever. Move the stage until the bright circle is in the centre of the field of view. Then fix the stage in position, disengage the Bertrand lens and remove the centring aid. To secure specimen slides in frame inserts, press the middle of the leaf spring and slide in the coverslip in the direction of the arrow. Clamp the frame insert in the object guide.

Performance data of the incident light fluorescence illumination*

The Leica DM IRB microscope is preferably equipped with mercury or xenon gas discharge lamps for fluorescence applications as they offer higher intensity. However, a 12 V 100 W halogen lamp can be used as well.

Lamphousing performance data

Lamphousing 106*

Lamphousing 106 is equipped with a 12 V 100 W halogen lamp. The lamp holder is centrable in x and y direction. The aspherical collector can be focused. Lamphousing 106 is fitted with a diffusing disc and heat protection filter, but does not have a reflector.

Lamphousing 106 z*

Like lamphousing 106, but additionally with centrable and focusable reflector and 4- to 6- lens collector. A quartz collector is available on request. The following lamps can be used (each have their own holder):

12 V/100 W halogen lamp (A.C.)

Ultra high pressure 50 W Hg lamp (A.C.)

Ultra high pressure 100 W Hg lamp (D.C. stabilised/non-stabilised)

Ultra high pressure 100 W Hg lamp

(D.C. stabilised/non-stabilised, type 103 W/2)

High pressure 75 W xenon lamp (D.C. stabilised/non-stabilised).

Lamphousing 107/2

The shield connection of the lamphousing is screwed to the potential equalisation point of the 12 V 100 W power unit. This lamphousing for transmitted and incident light has a fixed 1-lens collector and a fixed 12 V 100 W lamp.

!n. b.

Lamphousings LH 105 have been replaced by lamphousings LH 106. However, they are compatible with LH 106 lamphousings and can also be used.
