Laser Mechanical Shutter

SKU: NMLS

The NMLS Series Laser Mechanical Shutter functions as a laser safety interlock for laser processing systems, employing a precision torque motor to position a high-power dielectric mirror at approximately 45° to the laser beam path. In the default (unpowered) state, the mirror redirects the laser beam into an integrated beam dump heat sink for safe energy dissipation. When activated, the shutter opens to allow the laser beam to pass through. The unit features a standard 5 mm aperture compatible with most beam sizes and supports various dielectric mirror coatings optimized for wavelengths including 450 nm, 550 nm, 1060 nm, 1550 nm, and 2000 nm (CO₂). The standard configuration is an OEM package with an electrical control connector, while an optional version includes a built-in driver with BNC TTL input and a 24 V power supply for plug-and-play operation. The NMLS incorporates position sensors for both open and closed states and generates an alarm signal if the position detection fails. For long-term operation, the shutter must be mounted on a heat sink to effectively dissipate absorbed laser energy.
