Attention! You can customise this product to your needs.
Enhanced version incorporates rotating quartz λ/2 phase Waveplate and one or two thin film polarizers. Polarizers are housed in special design opto-mechanical adapter, which is mounted in precision opto-mechanical holder 5APH79T-1. Half waveplate rotates the polarization before TFP, which separate s-polarized and p-polarized beams. The intensity ratio of separated beams is continuously tuned by rotating the waveplate in the holder.
varna Ideal for femtosecond applications
varna Divides laser beam into two parallel beams of manually adjustable intensity ratio
varna Large dynamic range
varna Negligible beam deviation
varna High Optical damage threshold
varna Low dispersion for femtosecond and high energy laser pulses
