Visible & Near-IR Laser Line Polarizing Cube Beamsplitters

Beamsplitters are optical components used to split input light into two separate parts. Beam splitters are common components in laser or illumination systems. Beamsplitters are also ideal for fluorescence applications, optical interferometry, or life science or semiconductor instrumentation. Light can be split by percentage of overall intensity, wavelength, or polarization state.
