Introduction:
When the Non-Polarizing beamsplitter is mounted at 45 degrees with respect to a beam of blue-band light of 400-450nm range, it separates the beam into two orthogonal beams. The ratio of the power in the beams is determined by the coating. Typical ratios are R10:T90, R30:T70 and R50:T50.
