SKU: NSFF
The NanoSpeedTM Fiber In and Free-Space Out switches are fast laser beam shutter device featuring very low loss, fast response, and high optical power handling. The design uniquely provides a way to modulate/switch laser beam from a large core fiber. This is achieved using patented non-mechanical configurations with solid-state all-crystal designs, which eliminates the need for mechanical movement and organic materials. The NS fiber-optic switch is designed to meet the most demanding switching requirements of ultra-high reliability, fast response time, and continuous switching operation. The switch is bidirectional. The free space out put has a collimating lens, which can be customer designed.
The NS Series switch is controlled by 5V TTL signals with a specially designed electronic driver having performance optimized for various repetition rate.

[2] Measured without connectors. For other wavelength, please contact us.
[3] Measured at 5kHz, which may be degraded at higher repeat rate. Measured using a multimode laser with CPR ~14. Higher CPR lowers the on/off ratio
[4] Defined at 1310nm/1550nm. For the shorter wavelength, the handling power may be reduced, please contact us for more information.
