• Field proven with largest installed base
  • Broadest tuning range:
    680 nm to 1300 nm for maximum flexibility
  • High power across tuning range: >2 W at 900 nm,
    >1.6 W at 1100 nm

The new InSight® X3 is the third generation of Spectra-Physics’ industry leading InSight platform, specifically designed for advanced multiphoton microscopy applications.

Based on patented technology1, InSight X3 features a broad 680 nm to 1300 nm continuous, gap free tuning curve from a single source, nearly double the tuning range of legacy Ti:Sapphire ultrafast lasers. InSight X3 delivers high average and peak power levels across the tuning range, including critical near infrared wavelengths above 900 nm for deepest penetration in-vivo.

With Spectra-Physics’ integrated and patented DeepSee, the industry standard dispersion pre-compensator, the short pulses are optimally delivered through a microscope to the sample for maximum fluorescence and penetration depth. InSight X3 also has exceptional beam pointing stability, beam quality, output power stability, and fast wavelength tuning. This makes it ideal for many multiphoton microscopy techniques.

When equipped with the fixed 1045 nm dual beam option, InSight X3 fully supports the diverse needs of multimodal imaging. The two synchronized output beams enable easy simultaneous imaging of various fluorescence proteins (for example GFP and mCherry) and genetically encoded calcium indicators (GCaMP6 and jRGECO1a), SHG/THG imaging, and advanced imaging techniques such as CARS and SRS.

1. Due to our continous improvement program, specifications may change without notice.
2. Specifications only apply to the wavelength noted.
3. Specification applies to 900 nm (tunable) or 1041 nm (fixed), respectively.
4. Specification represents rms noise measured in a 10 Hz to 10 MHz bandwidth.
5. Percent power drift in any 2-hour period with less than ±1°C temperature change after a 1-hour warm up.
6. A sech2 pulse shape is used to determine the pulse width as measured with a Newport PulseScout® autocorrelator.
7. Avoid obstructing the air exhaust grills which will result in the recirculation of hot exhaust air. Cooling air enters through the front panel and exits through the rear fan apertures.
8. The InSight X3 is a Class IV – High-Power Laser, whose beam is, by definition, a safety and fire hazard. Take precautions to prevent exposure to direct and reflected beams. Diffuse as well as specular reflections can cause severe skin or eye damage.
