• Perrin Brocker Prism is a kind of Brewster Dispersion Prism, which has a characteristic of emitting at right angles to the direction of incidence.
• When the YAG laser is injected at the Brewster angle, the fundamental wave (1064 nm) and the double wave (532 nm) can be separated.
• Because the Brewster angle and critical angle are used, there is no loss due to reflection, resulting in high transmittance.
• The Perambrocka prism has no coating and can be used with high-energy pulsed lasers.
• Use to match the angle at which the light intensity of the fundamental (invisible) or double (green) YAG beam reflected at the prism incidence plane is minimized (Brewster angle).
• Convert the polarization direction of the laser beam so that it is parallel to the bottom of the prism.
• It can also be used for the spectroscopy of Ar laser with multi-wavelength oscillation.
• * The emission beam of the ultraviolet wavelength is not reflected because it deviates from the Brewster angle.
• * It can also be used as a non-polarized dispersion prism, but it will not emit light at right angles to the angle of incidence unless it is made incident at the Brewster angle.
• * Spectroscopy is possible even when an S-polarized laser beam is injected, but reflection loss occurs at the incident and outgoing surfaces.
• * Fingerprints and dirt on the uncoated surface will prevent total reflection and no reflection.
• * Do not let anything come in contact with the no-coat surface.
• * Measured dimensions A and B include chamfers, so they are slightly shorter.
• * The tolerance is defined at the intersection of each face without chamfers.
