PRODUCT UPDATE TEST AND MEASUREMENT SAFETY
Passive laser safety clothing
Protect Laserschutz, in collaboration with its
NanoScan 2s profiler
Ophir-Spiricon has released the latest version of its high power, scanning slit beam profiler, NanoScan 2s. Now available in a more compact size, NanoScan 2s is a NIST-calibrated profiler that measures beam position and size with sub-micron precision for CW and kilohertz pulsed lasers. The profiler offers silicon, germanium, or pyroelectric detectors; this allows profiling lasers of any wavelength, from UV to far infrared and to 100μm. New NanoScan 2s software, available in standard and professional versions, allows users to custom configure the display interface. The profiler uses moving slits – one of the ISO standard scanning aperture techniques – to measure beam sizes from micrometres to centimetres at beam powers from microwatt to kilowatt. The natural attenuation provided by the slit allows the measurement of many beams with little
or no additional attenuation required. The digital controller provides deep, 16-bit digitisation of the signal for high dynamic range up to 35dB power; this makes it possible to measure beam size and beam pointing with three- sigma precision to several hundred nanometres. The silicon or germanium detector-based profilers include an integrated 200mW power meter that displays both total power and individual power in each of the beams. The software can measure from 1 to 16 beams in the aperture with sub-micron precision. A beam can be found in less than 0.3 seconds and real-time updates can be displayed to 20Hz.
Ophir has also launched the latest version of BeamWatch, a non-contact beam monitoring system for high power YAG, fibre, and diode lasers used in industrial material processing applications.

partners Spezialtextilwerk Funke and Held, has added passive laser safety clothing and laser safety gloves to its product portfolio. The development of both products was part of a project funded by the German Federal Ministry for Economic Affairs and Energy (BMWE).
The new Bodyguard laser safety clothing is certified for the entire wavelength range from UV to IR.
It gives power densities between 1,000-10,000kW/m2
, depending
on the wavelength of the laser. The highest power densities are attained in the 315-1,400nm wavelength range. The clothing is breathable and washable, a particular advantage with respect to other products, especially for procedures performed under high-temperature conditions. The clothing can also be used for a variety of welding jobs that do not necessarily involve working with lasers.

Ever-Guard laser safety curtains
Laser Components has introduced laser safety curtains made of metal panels. The curtains can be mounted to the ceiling, moved freely, and offer the protection of metal screens. The individual panels are approximately 25cm wide, are movable due to the hinges they are equipped with on both sides, and are available for delivery at any height requested. The honeycomb-like surface
structure absorbs and disperses laser radiation; the material
is suitable for all standard wavelengths and certified according to DIN EN 12254. By applying the same assembly material used in the SLC- 250WB textile curtains, different configurations (L forms and U forms) can be implemented. Laser protective windows can also be integrated into the panels. The protection levels of the
Ever-Guard curtains correspond to those of the PT-EVG material used in metal screens, and the power density is 12MW/m².
