The fluorescent plate was designed to be field replaceable and can be ordered. The part number to order is 11597-103 and it can be ordered by contacting our service department at service@us.ophiropt.com.
The LBS-300HP-NIR uses specially treated material that provides extremely low reflection and high laser damage threshold, enabling beam attenuation by around a million times while keeping all beam parameters. This extreme attenuation enables measuring High Power laser beam profile focused on a beam profiler CCD.
Yes, the main function of LBS-300HP-NIR beam splitter is Beam profiling, however it performs a 3-way beam splitting:
Less than 0.0001% (1/10⁶) of the beam is reflected in one direction and less than 0.1 % in another while remaining 99.9% of incident laser beam is transmitted.
This allows user to measure one of the 3 beams, depends on available power measurement equipment and setup convenience.
Verify that the Optical Scaling (Magnification) is set to the correct value, as listed on the label of the WB-I unit
Yes, but the accuracy will be lower than what is listed in the specification.
System absorbs 20% of the power, the other 80% is back diffused from the WB-I. 200W is acceptable in continuous mode; higher power depends on environmental conditions and time of use.
The WB-I is optically aligned and calibrated for use with of any combination of 2 Ophir ND1 or ND3 filters. Other filters have a different thickness and use of them will affect the measurement accuracy
