User Guide to the IBIF Leica TCS SP8 MP Confocal Microscope 

This version: 7.24.14. 

Introduction 

The IBIF confocal microscope is made available on a fee-for-use-hour basis to all users who have been 

trained. Unlike our previous instrument, it has a number of hardware features, specifically the 

objectives, the stage, and the condensers, that can be added or removed by the user, with the 

permission of the Imaging Specialist. To minimize inconvenience to other users, and to reduce the risk 

of inadvertent damage to the equipment, we ask that users obey two rules: 

1)

 

Leave the confocal as you found it. Replace and/or reset everything that you modified. 

2)

 

Be aware that other users may have failed to obey rule 1. Be alert, especially in regard to 

mechanicals such as stage translation, condenser height, and objective rotation. 

Thank you, and we wish you every success in your imaging. We are here to help. 

The Confocal Microscope and Accessories 

The instrument is a Leica TCS SP8 MP confocal 

microscope, equipped for multi-photon confocal 

microscopy. The components are the microscope 

body, two automated stages, the scan head, the 
electro-optical modulator (EOM), the monitor 

and computer, and the Spectra-Physics Mai-Tai 

tunable near-IR laser. 

 

 

 

 
 

 

 

 

The items on the desk (along with the monitor, 

keyboard, and mouse) consist of a confocal 
controller, a microscope controller, a metal-

halide power source (which performs the 

function of the Hg bulb in the previous system), 

and a controller for the Dodt contrast 

enhancement system (which replaces the 

Nomarski contrast enhancement method of the 
previous system). 

The unlabeled switch is a shutter for the 

Mai Tai laser and should only be needed in 

emergencies in which the beam is exposed.
