deltaEmerald
Dual Color SRS Imaging

The new deltaEmerald allows simultaneous SRS imaging of twovibrational bands with its revolutionary dual color SRS (DC-SRS)
scheme. It is aimed for users at the forefront of SRS microscopy, given
the best signal-to-noise performance and the capability of backgroundsubtraction as well as simultaneous imaging of two vibrational bands.
Two Stokes pulses, separated by 85 cm-1 and modulated at different
frequencies are overlapped with the tunable Pump pulse.

Dual Color SRS Imaging

The pulse length of about 1 ps, 10 cm-1 ... 15 cm-1 bandwidth andseveral 100 mW output power in each beam are ideal parameters for
Coherent Raman imaging.
The pulses of all three beams are shot noise limited due to solid statelaser design and proven OPO technology. The shot noise limited -162
dBc/Hz above 1 MHz (limited by the noise measurement setup with
4.8 mA) allows for fast image acquisition and superior signal-to-noiseratio.
Fully automated tuning, power control and temporal overlap of all
three beams are given.
Additional a ~100 fs-output at 1030 nm is provided for efficient SHG
and two-photon imaging.

▪ Innovative SRS scheme for simultaneous excitation of two vibrational band
▪ Tunable Pump and both Stokes pulses are spatially and temporally overlapped▪ Spectral distance of Stokes 85 cm▪ Proven OPO technology with shot noise limited performance with -162 dBc/Hz above 1 MHz▪ Additional femtosecond output at 1030 nm for optimum SHG and TPF excitation-11

Applications

1. Simultaneous imaging of CH2 & CH3 for nondestructive and fast
Coherent Raman histology. The 85 cm-1 difference is chosen to address
CH2 & CH3 with 2845 cm-1 and 2930 cm-1 at their peak position.
2. Background removal of non-resonant artefact's, especially
important for weak signals in the fingerprint region.
3. Cosmetics / pharmaceutical imaging and further applications.
