Shutters

U.S. Laser offers a line of shutters designed to either block or deflect laser beams. All shutters are electromechanically actuated, and are designed for fail-safe operation, where the shutter closes by gravity in case of solenoid failure.

Safety Shutter Assemblies

U.S. Laser safety shutters feature a rotary solenoid actuated stainless steel flag, and are designed for intracavity use. The housing is fabricated from aluminum, and black anodized. The assembly includes an emission eminent warning light, and is conveniently wired to a five pin Switchcraft connector. Shutter assemblies come mounted on a standard U.S. Laser carriage mount.

Safety Shutter Assemblies with Mirror Mount

This is the same shutter assembly as described above, but mounted on a common carriage with a Model

N1008 mirror mount.

High Power Shutter with Mirror Mount

Features a completely redesigned shutter assembly for use with high power lasers. All electrical wiring is isolated from the beam area, and the shutter is repositioned to provide additional cover clearance. This shutter also has a high temperature silicone rubber dust seal which will withstand temperatures to over 400 °F. The shutter is directly compatible with all existing high power shutter/mirror mount assemblies, and is now shipped as standard equipment on all USL high power systems.

Beam Deflection/Gating Shutter Assemblies

Low Power Beam Dump Shutter Assemblies

These compact beam deflection shutters are designed to be used extracavity to deflect or redirect laser beams up to 12mm diameter into a suitable absorber or power detector. Design is similar to the safety shutters described above, except that the shutter flag is gold plated to reflect >95% (at wavelengths of 0.7 to 20 microns) and mounted at a 45° angle to deflect the beam into an absorber or power detector. All beam deflection shutters are supplied on a U.S. Laser carriage mount.

Moderate/High Power Beam Dump Shutters

This heavy duty series of beam dump shutters is designed for use with high power continuous and pulsed lasers in the range of 100 watts to <1 KW and beam diameters up to 19mm. Functionally, the beam dump shutter is placed extracacity, in the beam path . When the shutter is de-activated, the incoming laser beam is deflected 90°. When voltage is applied to the solenoid, it rotates the mirror out of the beam path, fully transmitting the incoming laser beam.

To accommodate a range of applications, the reflector mirror is available in three different configurations, each of which will easily accommodate beam diameters of up to 20 mm.. A gold plated copper arm is available for use at lower power levels. This mirror has a reflectivity of > 95% at wavelengths from .7 to 20 microns, and is a lower cost alternative to dielectrically coated mirrors. The second version uses a highly damage resistant dielectrically coated fused silica mirror, and is coated to reflect >99% of the incident 1064 nm beam. The third version uses the same dielectrically coated mirror, with the addition of an optical filter designed to transmit visible light while blocking any 1064 nm laser light leakage. This version is designed to be used with high power 1064 nm lasers which are equipped with integral visible spotting lasers. For pricing and availability of dielectrically coated mirrors for use at wavelengths other than 1064 nm, please consult our sales department. The shutter mirror is actuated by a heavy duty 24 volt DC solenoid, and is equipped with an emission light, and a shutter position interlock switch. The deflected beam is designed to be absorbed by either a continuous duty water cooled absorber (see part no 1039), or a high power detector assembly (see part no 1036), both of which are listed in the power meter section of this catalog, and are sold separately.
