Broadband Non-Polarizing Cube Beamsplitters
• Low Polarization Dependence: |Ts-Tp|<6%
• Constructed from High Tolerance Right Angle
Prisms
• BBAR Coated Faces for Maximum Efficiency
TECHSPEC® Broadband Non-Polarizing Cube
Beamsplitters consist of a pair of precision high tolerance
right angle prisms cemented together with a metallic
dielectric coating on the hypotenuse of one of
the prisms. The low polarization dependence of the
metallic dielectric hybrid coating allows the transmission
and reflection of S- and P-polarization states to
be within 6% of each other. These beamsplitters are
spectrally flat across their specified wavelength ranges,
reducing effects caused by changes in the angle of
incidence or converging/diverging beams. See page 188 for C-Mounted Cube Beamsplitters

• Visible and NIR Coating Options Offered
• 500:1 Extinction Ratio
• AR Coated for <0.5% Reflection per Surface
Designed for broadband applications, TECHSPEC®
Broadband Polarizing Cube Beamsplitters offer a
transmission of greater than 90% for P-polarized
light and a reflection efficiency of greater than 99%
for S-Polarized light across the entire design wavelength
range. Each beamsplitter consists of a pair of
precision high tolerance right angle prisms cemented
together with a dielectric coating on the hypotenuse
of one of the prisms. An anti-reflection (AR) coating
has been applied to each face of the beamsplitter to
achieve less than 0.5% reflection per surface.
