Standard Cube Beamsplitters
• Multi-Layer Dielectric Coating
• Several Beamsplitting Ratios Available
• Multiple Sizes Available
Constructed by cementing two right angle prisms together, TECHSPEC® Standard Cube Beamsplitters offer
a range of reflection/transmission ratios. An interference coating has been applied to the hypotenuse
surface of one of the prisms to provide the designated reflection/transmission ratio. Absorption loss to the
coating is minimal. Note: Output is partially polarized, making TECHSPEC® Standard Cube Beamsplitters
suitable for illumination and other applications where polarization is not a concern. If polarization sensitivity
is critical to your application, we recommend using TECHSPEC® Polarizing Beamsplitters or TECHSPEC®
Non-Polarizing Beamsplitters.

• Optically Contacted Design Increases Damage Threshold and Eliminates Cement Fluorescence
• Greater than 96% Transmission of P-Polarized Light
• High Extinction Ratio of Greater than 1.000:1
Laser Line High Energy Polarizing Cube Beamsplitters are an easy-to-mount, high contrast alternative to
Brewster windows. Laser Line High Energy Polarizing Cube Beamsplitters feature greater than 96% transmission
of p-polarized light, along with an λ/6 surface flatness for minimal wavefront distortion. To increase
the laser damage threshold and eliminate fluorescence, these polarizers are constructed by optically contacting,
rather than cementing, UV Fused Silica Right Angle Prisms. Laser Line High Energy Polarizing Cube
Beamsplitters are available for use with a variety of common Nd:YAG laser wavelengths.
