SIGMAKOKI Pellin-Brocker Prism

Perrin-Brocka prisms are a type of Brewster dispersion prism, and have the characteristic of emitting at a right angle to the direction of incidence. When a YAG laser is incident at the Brewster angle, the beam can be separated into the fundamental wave (1064 nm) and the double wave (532 nm). Since the Brewster angle and critical angle are used, there is no loss due to reflection and high transmittance can be obtained. Perrin-Brocka prisms are not coated, so they can be used with high-energy pulse lasers. Use them at the angle (Brewster angle) that minimizes the amount of light of the YAG fundamental wave (invisible light) or double wave (green) beam reflected at the prism entrance surface. Please convert the polarization direction of the laser beam so that it is parallel to the bottom surface of the prism. It can also be used for spectroscopy of multi-wavelength oscillation Ar lasers. *The ultraviolet wavelength output beam is outside the Brewster angle, so it is not non-reflecting. *It can also be used as a non-polarized dispersion prism, but if it is not incident at the Brewster angle, it will not emit at a right angle to the angle of incidence. *Even if an S-polarized laser beam is incident, it can be split into two beams, but reflection loss occurs at the entrance and exit surfaces. *If fingerprints or dirt are left on the uncoated surface, the total reflection and non-reflection effects will not be obtained. *Do not allow the uncoated surface to come into contact with anything. *The actual A and B dimensions include chamfering, so they will be slightly shorter. *The dimensional tolerance is defined at the intersection position of each surface, not including the chamfering.
