FAQEach standard laser shutter has a maximum average power rating that should never be exceeded. This rating will depend on the laser’s wavelength (or multiple wavelengths), whether the laser is CW or Pulsed, etc. The optics on most laser shutters may be customized to your application.
Your laser shutter is guaranteed to operate in the orientation recommended by the manufacturer. If needed, laser shutters with small and lightweight components can be mounted in an alternate orientation without much concern for the effects of gravity. Laser shutters equipped with heavier optics may be calibrated and paired with a calibrated controller for certain orientations if requested at the beginning of the program.
Yes! Operating the laser shutter for any amount of time without an unobstructed thermal path to an “infinitely large” heatsink will result in overheating and performance degradation. Permanent damage will occur before the laser shutter’s internal temperature reaches 110 °C (230 °F).
Our controllers have three connections: power supply (+24 VDC/COM), shutter (+/-), and control (5V trigger) signal (+/-). Please consult the wiring diagram provided with your controller series or request a copy by contacting our NM Laser sales team.
This is not recommended. Adding a few feet of wire (plus additional connection losses) could drop the power below the recommended operating threshold. This will result in reduced performance, overheating, and in some cases, the laser shutter may cease to operate for no “apparent” reason.
NM Laser shutters are designed for high reliability and lifetime. Depending on product lines, operating conditions, and application, laser shutter lifetime can range from 100 million to 2 billion cycles.
Yes, technically you can operate the shutter control board using software such as LabVIEW to generate a control signal (may require additional National Instruments hardware). You will still need to provide the laser shutter / board power via an appropriately rated 24V external power supply.
