Overview of Leica TCS SP8 Scan Head Components and Options

This document provides a detailed list of components and optional features available for the Leica TCS SP8 Scan Head, a sophisticated laser scanning microscope system.

Main Components and Features

• Laser Sources: Includes visible line lasers or white light laser, infrared (IR) lasers, ultraviolet (UV) lasers, and STED laser options for advanced super-resolution imaging.
• Optical Filters and Modulators: Acousto-optical tunable filter (AOTF), electro-optical modulation (EOM), and direct modulation (DMOD) options enable precise wavelength selection and modulation control.
• Beam Handling: Acousto-optical beam splitter (AOBS) with alternative configurations, incoupling options for IR, UV (with CS2 UV optics), and STED lasers, and outcoupling via X1 port.
• Scanning and Detection: Field of view (FOV) scanner with tandem scanner option, scan optics with alternative coatings (UVIS, HIVIS, VISIR), scan field rotation using Abbe-König rotator, and reflected/transmitted light detection in non-descanned positions.
• Detection Modules: Square confocal pinhole, fluorifier disc, external detection capabilities, prism-based dispersion, and multiple detector options including up to five photomultipliers (PMTs) or up to four hybrid photo-detectors (HyDs).
• Additional Features: Monitoring diode for Setlight, FRAP booster for fluorescence recovery after photobleaching experiments, and objective lens options tailored to specific imaging needs.

Optional Components

Several components are marked as optional, allowing customization based on experimental requirements. These include IR lasers, UV lasers, STED laser, scan field rotation, reflected and transmitted light detection in non-descanned positions, fluorifier disc, external detection, and hybrid photo-detectors.

Significance of Components

• Laser Variety: Enables multi-wavelength excitation for diverse fluorophores and advanced imaging techniques.
• Modulation and Filtering: Provide flexibility in wavelength selection and temporal control of laser excitation.
• Detection Flexibility: Multiple detection options and configurations enhance sensitivity and spectral resolution.
• Scanning Options: Tandem scanning and field rotation improve imaging speed and orientation adaptability.

This modular design allows users to tailor the Leica TCS SP8 Scan Head to specific research needs, balancing performance, flexibility, and advanced imaging capabilities.
