Description

The fiber-coupled electro-magnetic shutter 48EMS-0 is a shutter that can be controlled by means of a TTL signal (flank-controlled).
An appropriate controller is available separately.

Fiber-coupled setup
The electromegnatic shutter is fiber-coupled using two Laser Beam Couplers, one of which serves as the input into the opto-mechanical unit collimating the input radiation and a second coupler that couples the radiation back into the second fiber cable. The stability of the total Fiber-to-Fiber Coupler is determined by the stability of the Laser Beam Coupler.

Depending on the choice of lens type (monochromatic or achromatic) within the Laser Beam Couplers, the system can either be used for a single wavelength or for a wavelength range.

Coupling focal length
The best focal length for the 60SMS Laser Beam Couplers used in these systems is f' 11 - 12 mm. If the effective numerical apertures of the two fibers used with this system are different, you have to use two Laser Beam Couplers with different focal lengths.

Configuration
For selecting the 60SMS Laser Beam Couplers please refer to the 60SMS Laser Beam Coupler webpage.

If you want to use the electro-magnetic shutter in a free beam setup, please refer to 48EMS-6.
