On/Off Lever Positions
Internal and External SM1 Threading (1.035"-40)
SM1 Lens Tube System Compatible
Clear Aperture when Open: 7.2 mm (0.29")

The SM1SH1 Manual Beam Shutter provides a convenient "Open/Closed" labelled switch for propagating a beam through an optical assembly. The lever-actuated shutter is firmly held in position with a precision detent mechanism at both the opened and closed locations. The shutter has internal SM1 lens tube threads on one side and external SM1 threads on the other side, making it ideal for use with our lens tube systems. Please note that it is not recommended to use the SM1SH1 within a 30 mm cage system as the cage rods will interfere with the lever actuator of the shutter.

What is the maximum power from a parallel beam that this shutter would handle? Thanks

Response from Javier at Thorlabs to david.merino: Thank you very much for contacting us. We currently do not have a precise laser induced damage threshold value for this shutter; however, since the shutter material is aluminum, the power required in order to ablate it is in the order of tens to hundreds of Watts.

Response from Javier at Thorlabs to jc7: yes, the lever would be blocked by the cage rods. We will look into designing a cage compatible shutter based on the SM1SH1. I will contact you directly with more details.

Hello, Would the lever of the SM1-Threaded Manual Beam Shutter (SM1SH1) be blocked by the rods of a 30mm cage system? Thank you, James.
