Dielectric cube half mirrors consist of two right angle prisms. One of them is coated with dielectric multi-layer partial reflection coating on the hypotenuse face.

◦Half mirror divides input beam into reflectance and transmittance at a 1:1 ratio. A beamsplitter with R:T (1:1 ratio) is called “Half Mirror”.
◦Four surfaces of the cube are coated with multi-layer anti-reflection coatings.
◦The loss of input beam is minimized as there is no absorption from dielectric coating. However the reflection to transmission ratio of these dielectric cube half mirrors vary depending on wavelength, polarization and the incident angle of input beam.

▶For a guarantee in reflected wavefront error or transmitted wavefront error, please contact our Sales Division.

Attention

▶Input beam from the prism side is indicated by a “○”. Reflection and refraction over wavelength will differ when light input is applied from the opposite side of the prism.
▶The transmittance curves are based on actual measurements and may vary with manufacturing lots.
▶The surface flatness is the reflected wavefront distortion of the surface before coating.
▶Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
