Optores (PW booth 860, Bios 8860) will demonstrate the latest upgrade to its NG-FDML series of wavelength-swept lasers. The company will also be launching the new 3 MHz imaging speed option. 

Double as fast as previous versions, the new device is ideal for optical coherence tomography (OCT) in medicine, biology and industrial inspection. Multi-MHz sweep rates are necessary for high-resolution 4D-OCT, which shows threedimensional tissue structure live and in real time.

The new lasers are available at three popular wavelengths for OCT: 1,060nm, 1,310nm, and 1,550nm. They offer very high output power and centimetres of coherence length for highquality OCT images. Optores’ core technology is Fourier-domain mode-locking (FDML), which plays a crucial role for MHz-OCT.
