Laser Specifications

Output Specifications
Single VLE maximum output power ≤ 500 mW Maximum of 2 lasers can be turned on at once under Fusion control. This is an IEC 60825-1 classification value and is far greater than in normal use. See the ‘specifications for the individual lasers on the following pages and more information in
Dual-VLE BCU maximum output power ≤ 500 mW Maximum of 4 lasers can be turned on at once under Fusion control. See previous note.
Operating wavelength range 400 to 800 nm  
Output Fibre
Fibre type Multimode (MM)  
Connector type FC/APC  
Beam Divergence
Beam divergence at internal module output 0.5-3 mrad (full angle) The divergence depends on the properties of the laser inside the VLE.
Beam divergence at VLE coupler output 0.025-0.13 NA (3-15 degrees full angle)
Beam divergence at VLE 50 μm fibre output ≤0.12 NA (14 degrees full angle)  
Beam divergence at VLE 25 μm fibre output ≤0.10 NA (12 degrees full angle)  
Beam divergence at BCU fibre output ≤0.14 NA (16 degrees full angle)  
Beam Diameter
Beam diameter at internal module output 0.3 - 3 mm The diameter depends on the properties of the laser inside the VLE
Beam diameter at VLE coupler output 20 - 100 μm
Beam diameter at VLE 50 μm fibre output 50 μm  
Beam diameter at VLE25 μm fibre output 25 μm  
Beam size at BCU fibre output 175 x 175 μm Fibre has square profile, so beam is square at fibre output
