iChrome TVIS: Tunable Visible Picosecond Fiber Laser (488 – 640 nm)

- Continuously tunable in the visible range (488 - 640 nm)
- Fiber coupled output (single-mode)
- Fully automated operation
- Pure color, narrow emission bandwidth (< 4.5 nm)
- Picosecond pulses (3.5 ps ± 1 ps)
- Perfectly suited for fluorescence lifetime imaging microscopy (FLIM) or optical testing of components
The iChrome TVIS laser system is a fiber laser with the flexibility to set automatically the laser output to any wavelength in the visible – from 488 nm to 640 nm. The coherent laser output ensures that the visible light exhibits the best intensity noise performance and the use of polarization maintaining optical components a stable linear polarization of the fiber coupled output beam is achieved. In contrast to conventional white light sources, the narrow bandwith laser pulses are not filtered from an intrinsically noisy supercontinuum. The entire laser system is extremely user friendly: No alignment procedures of any optical components distract the user from the main task – to produce results.
