APE OPO Compact Chameleon

Chameleon OPO

The Chameleon Compact OPO (optical parametric oscillator) is the first completely hands-free, fully automated and computer controlled OPO. One of its major features is the independent tuning of the pump as well as OPO output wavelengths.

When used with the Chameleon pump laser from Coherent, it is perfectly suited as a light source for MPE (Multi Photon Excitation) microscopy. The combination of the Chameleon and the Chameleon Compact OPO covers a wavelength range of 680 … 1600 nm, with an optional, gap-free expansion to the deep UV (< 200 nm) through the use of a HarmoniXX SHG/THG/FHG module pumped by the Chameleon.

Alternatively, the Chameleon compact OPO VIS includes an automated module for SHG of Ti:Sa and OPO Signal.

Significant advantages for laser scanning microscopy are:

Higher penetration depth and less photo damage of the sample due to excitation wavelengths >1 µm
Simultaneous imaging of different fluorophores possible, for instance exciting GFP (green fluorescent protein) with the pump laser and RFP (red fluorescent protein) with the OPO
Multi-modality of the system, providing access to alternative imaging methods, e.g. SHG/THG, coherent Raman scattering.
