Spectra-Physics introduces InSight™ DeepSee™, an extraordinary new ultrafast laser system that takes multiphoton imaging to new depths. Based on patented technology, the new InSight DeepSee delivers nearly double the tuning range of existing ultrafast lasers and provides seamless access to long infrared wavelengths for deepest in vivo imaging. Robust and fully automated, InSight DeepSee provides easy-to-use, hands-off operation, freeing users to focus on their critical research.

InSight DeepSee features an unprecedented 680 nm to 1300 nm continuous tuning from a single source, short 100 fs pulse widths and highest peak power levels into the infrared where imaging penetration depth is maximized. Spectra-Physics’ integrated patented DeepSee, the industry standard dispersion pre-compensator, delivers the short pulses through a microscope to the sample for maximum fluorescence. InSight DeepSee also has exceptional beam pointing stability, beam quality and output power stability, making it ideal for microscopy.

A dual wavelength option with a second output beam complementing the main tunable output is available for advanced imaging techniques including uncaging, CARS imaging and multimodal imaging. This fully automated ultrafast laser can be seamlessly tuned with the click of a mouse to any wavelength within seconds at speeds over 50 nm/sec. InSight DeepSee is designed, built and tested to our highest quality standards for reliable hands-free operation.

Applications

1. Due to our continous improvement program, specifications may change without notice
2. Specifications only apply to the wavelength noted
3. When configured with the Dual Option, average power specifications are reduced by 10%. Contact factory for additional specifications with this option.
4. Specification applies to 900 nm only
5. Specification represents rms noise measured in a 10 Hz to 10 MHz bandwidth
6. Percent power drift in any 2-hour period with less than ±1°C temperature change after a 1-hour warm up
7. A sech² pulse shape is used to determine the pulse width as measured with a Newport PulseScout^® autocorrelator
8. 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.
9. The InSight DeepSee 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.
