Confocal Microscopy

Confocal Microscope | Leica, TSC SP5 II

Location: LFG, Haberstraße 9a, 91058 Erlangen, Room U1.825

The Leica TCS SP5 confocal microscope covers a wide range of confocal and multiphoton imaging requirements with outstanding overall performance. The system offers the full range of scanning speeds at the highest resolution. With its proven, highly efficient SP detection (up to five channels simultaneously) and the optional AOBS (Acousto Optical Beam Splitter), the Leica TSC SP5 delivers bright, noise-free images with minimal photodamage at high speed.
