LBS-300HP-NIR Attenuator

Beam Splitter for High Power Lasers NIR
 
 
Description: 

The LBS-300HP-NIR is a patent pending technology beam splitter for High Power lasers that allows measuring NIR (~1064nm) focused or collimated laser beam profiles up to 5kW or 15MW/cm².
 
The LBS-300HP-NIR operates by reflecting a fraction of the incoming beam through the front surface of each of a pair of orthogonally oriented wedges. Less than 0.0001% (1/10 ⁶) of the beam is reflected towards the Ophir Beam Profiler Camera. This enables beam shape, focal spot, beam waist, M² of a highpower laser; up to 5kW or 15MW/cm².
 
Relative power can be measured by placing an Ophir power sensor after the first wedge, thereby measuring the laser beam after being reduced to 0.1% (1/10³).
 
99.9% of the laser beam passes through, ideal for absolute power measurement.
 
Each optical path through the LBS-300HP-NIR provides uniform attenuation of any beam shape (Gaussian, flat-top, doughnut, etc.) while preserving the polarization and overall profile of the incoming laser beam thus providing accurate sample of incident beam. A 1.035-40 thread is provided behind each wedge along the axis of the output beam. These can be used to directly mount accessories with 1” lens tubes such as beam dumps or power/energy sensors.

Analyzing Small, High Power Beams at Focus in Manufacturing Applications

Lasers are increasingly deployed in manufacturing applications, being pushed to higher and higher output powers and smaller and smaller beam sizes to work faster and with higher precision. Determining the beam profile at the beam focus of these lasers is critical to verify and improve manufacturing product quality. However, there are enormous challenges that must be overcome to capture the beam profiling data. Read more...
