nmLaser laser shutters perform at switching speeds up to 50 ms

The new FlexSorb household of laser shutters features a high damages threshold, fast switching rate, little size as well as silent operation. The only relocating component is a low-mass, flexible, ferromagnetic cantilever membrane that is moved in and out of the light beam by non-contact electro-magnetic methods, considerably minimizing opening as well as closing shock, vibration as well as wear.

Engineers at nmLaser developed the FlexSorb laser shutter line with its non-contact flexure made to shut at a position somewhat far from the post, essentially drifting in air to get rid of any kind of potential resonance or bounce caused by effect deceleration of also the low-mass flexure.

These flexures are untouched by international fragments clinging to the magnetic pole and also offer much longer life times. Use particle buildup is exceptionally low, with off-the-shelf models ranked for clean area use. All units are immersion cleaning suitable and can be provided for clean room type applications.

Slightly overdamped controllers get rid of system ring, making certain reliable energy transfer to the magnet. The heat from the effective magnetic design is combined with the laser optical absorption warmth, and is dissipated using thermal conduction to a typical, hassle-free mounting surface, accomplishing premium thermal dissipation. The constructed in light beam dump absorbs high CW power levels with excellent damage resistance from high fluence pulsed lasers.

Engineered materials, geometry as well as surface morphology give really reduced backscatter from DUV through FIR wavelengths. Systems are designed for usage with 24 V type circuits with a timed impulse to open as well as a reduced voltage for long-term hold. Placement sensing units, both logic circuit and also mechanical switch, are offered on most versions.

Aperture dimensions vary from 3 mm to 14 mm. Fast switching rates target OEM safety interlock as well as processing application needs, varying from under 10 msec to 50 msec for bigger apertures.

" Our new FlexSorb line brings laser shutter modern technology right into the 21st century as well as marks a significant improvement in laser shutter performance," says nmLaser Products President David Woodruff. "Developments in electro-magnetic layout and also thermal dissipation make FlexSorb the laser shutter of option for even one of the most rigorous production and also research applications."
