CLSM - Leica SP8 inverse (Irchel)

CLSM_LeicaSP8_inverse

 

 

The Leica SP8 is an automated inverse confocal laser scanning microscope allowing simultaneous acquisition of 3 fluorescent channels and 1 transmitted light channel (BF). This system is ideal for fixed samples.

Location

University Zurich, Irchel Campus, Room Y55-K-41

Technical Specifications

Light sources and lasers

  • Halogen lamp for transmitted light
  • External fluorescence lamp  LQ-HXP 120
  • Solid state diode lasers: 405 nm (50 mW), 488 nm (20 mW), 552 nm (20 mW) and  638 nm (30 mW)

Scanners

Regular scanner: 10 - 1800 Hz

Objectives

Name Magnification NA Immersion WD (mm)
HC PL APO 10x 0.3 Air 11
HC PL APO CS2 20x 0.75 Imm 0.67
HC PL APO CS2 40x 1.1 Water 0.65
HCX PL APO CS2 63x 1.4 Oil 0.14

CS2 objectives: improved color correction, perfect VIS-405; IMM = multi immersion (either water, glycerol or oil) 

Detector System

Two Hybrid (HyD) detectors, one photomultiplier tube (PMT) detector and one additional PMT for transmission. Excitation controlled by AOTF, beam splitters: RT 15/85, substrate, TD 488/552/638, DD 488/552 for separation between excitation and emission. Accurate emission detection by spectral detectors.

Fluorescence Filters for widefield

Name Excitation Range Excitation Filter Dichroic Emission Filter
DAPI UV BP 350/50 400 BP 460/50
GFP blue BP 470/40 495 BP 525/50
RHOD green BP 546/11 560 BP 585/40

Remarks

This microscope acquires images with improved axial resolution compared with more conventional widefield microscopes. In addition to the multicolor images in fixed samples the microscope can acquire large tile/overview scans and/or several positions fully automatically.
