1 General Information
The OSW12(22)-xxxE Series of Switch Kits include a MEMS optical switch with an integrated
control circuit that includes an USB 2.0 interface for easy integration into your optical system. It
is available as 1x2 or 2x2 (1x4 and 1x8 on request) MEMS modules with operating wavelengths
of 488, 633, 780, 830, 980, or 1310 and 1550 nm. These bi-directional switches have low inser-
tion loss and excellent repeatability. The switching mechanism is based on silicon MEMS tech-
nology, which ensures high reliability, provides exceptionally low crosstalk between channels,
and is inherently very fast (switching time <1ms).
The OSW12(22)-xxxE switches are designed for the distribution and routing of signals at the in-
dicated visible or near infrared wavelengths. The switches can be controlled via USB2.0 by the
included GUI and driver package, via an on-board toggle switch, or via BNC input (TTL signal).
A seven segment LED display indicates the active channel.
By default, all switches are shipped without fiber connectors. Termination of the fibers is avail-
able upon request; please contact your local Thorlabs office or distributor for pricing. Addition-
ally, 1x4 and 1x8 MEMS switch modules are available on request.
The OSW12(22)-xxxE Series Switch Kits can be powered via the USB port or the onboard DC
power connector.
A universal 9 V wall power supply is included with these Switch Kits.
1.1 Safety
Attention
All statements regarding safety of operation and technical data in this instruction manual
will only apply when the unit is operated correctly as it was designed for.
The OSW12(22)-xxxE must not be operated in explosion endangered environments!
Only with written consent from Thorlabs GmbH may changes to single components be
made or components not supplied by Thorlabs GmbH be used.
This precision device is only serviceable if properly packed into the complete original
packaging. If necessary, ask for a replacement package prior to return.
Warning
When operating this unit with a laser be sure to pay strict attention to the safety recom-
mendations of the appropriate laser safety class of the used laser!
When operated incorrectly, this can cause severe damage to your eyes and health!
Do not look directly into any of the optical fiber terminations.
Cover any unused fiber termination.
Attention
The OSW12(22)-xxxE module is electrostatic discharge sensitive.
Observe the precautions for handling ESD sensitive modules.
Attention
Mobile telephones, cellular phones or other radio transmitters are not to be used within
the range of three meters of this unit since the electromagnetic field intensity may then
exceed the maximum allowed disturbance values according to IEC 61326-1.
This product has been tested and found to comply with the limits according to
IEC 61326-1 for using connection cables shorter than 3 meters (9.8 feet).
