中性密度+光束分束器组合

通常要求在到达相机之前降低激光功率，以获得不会导致相机光饱和或损坏的有用信号。这些系统首先进行一次或多次光束取样，然后通过光学密度滤光片吸收光束，从而降低激光功率。

  • LBS-300s衰减器

    LBS-300 Attenuator
    The LBS-300s beam splitter attachment for C-mount, CS-mount, or Ophir mount cameras allow you to measure laser beams with diameters up to 15mm and powers ranging from 10mW to ~400W(1). The beam sampler is designed so that the preferential polarization selection effect of a single wedge is cancelled out and the resulting beam image is polarization corrected to restore the polarization components of the original beam. The beam sampler operates by reflecting the incoming beam from the front

  • LBS-300HP-NIR Attenuator

    LBS-300HP-NIR Attenuator
    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

  • LBS-100衰减器

    LBS-100 Attenuator
    LBS-100系统不如上述LBS-300s紧凑，但具有更大的孔径，并具有更长波长的版本。该系统包含安装框架、1个楔形分束器和若干衰减器。LBS-100的出口端是标准C型接口螺纹，因此我们所有的相机都可以安装到框架上。楔角为6.5度，以确保来自背面的反射光不会进入相机。光学元件与可见光的1/4波齐平，以确保光束不变形。

  • LBS-400衰减器

    LBS-400 Attenuator
    LBS-400光束取样器可配合Pyrocam 相机，可测量直径最高达1英寸（25.4mm）、功率为10mW~500W(1)的UV或IR波长激光光束。光束取样器在设计上消除了单光楔的优先偏振选择效应，能得到经偏振校正的光束图像，以还原原光束的偏振分量。 (1)For Gaussian beam diameter <1/2 the clear aperture and depending on ND filter and camera saturation limits the maximum power may be as high as 1200W.
