波长范围

对于不同的波长范围需要不同透镜

M2-200s带有3个标准透镜，300mm焦距

M2-200s-FW

光束尺寸

0.5mm - 10mm M2-200s

随波长，束腰尺寸，和位置，M2变化

损伤阈值

相机

0.15 μW/cm2 CW mode for a 10 mm input beam diameter

1.0 μJ/cm2 pulse mode for a 10 mm input beam diameter

Both of the above for an M2 =1 @ 1064nm

1 CCD cameras can be damaged by power in excess of 100 mW/cm2 or energy in excess of 100 mJ/cm2. The M2-200s employs a focusing optic.While it may be that the laser input power or energy measures well below this damage threshold, it can easily exceed these levels when focused onto the camera sensor. Use caution and error on the side of safety. CCD cameras can be costly to repair or replace.
