SpectraPhysics InSight - Model X3+ and X3 -Tunable Ultrafast Lasers

The InSight platform is designed for advanced multiphoton microscopy in neuroscience, immunology, and other biological sciences. Based on patented technology¹, InSight is a hands-free, fully computer-controlled light source. It features a gapfree, 680 nm to 1300 nm tuning range which nearly doubles the accessible wavelengths when compared to traditional Ti:sapphire lasers. The InSight performance is optimized in the 900–1100 nm range to support the common green and red fluorescent proteins including GFP, RFP, GCaMP, jRGECO, and mCherry. With the InSight X3+ A increased output power, experiments using red flurophores in the 1200–1300 nm range can be performed.

InSight X3+ A and InSight X3 A are equipped with the standard, DeepSee integrated dispersion compensation to ensure pulse broadening effects are minimized. As a result, fluorescence signal and penetration depth are maximized. The integrated attenuators provide real-time adjustment of the output energy delivered to the sample. Their fast response time acts as a software-controlled switch that can be used to minimize exposure for delicate samples and to minimize backlash effects.

Both lasers can be equipped with a fixed 1045 nm dual beam option to support the diverse needs of multimodal imaging. The tunable and fixed outputs are synchronized which enables several applications including advanced imaging techniques such as CARS and SRS. The InSight also supports simultaneous, multi-wavelength excitation of fluorophores and/or genetically encoded calcium indicators, and second and third harmonic generation
microscopies.
