[Features]
· Pellin-Broca prisms are a type of Brewster angle dispersing prism and have characteristic emission at a right angle in regard to the incident direction.
· If irradiated using a YAG laser at Brewster's angle, it can split beams of fundamental (1,064 nm) and second harmonic (532 nm) waves.
· Because Brewster's angle and a critical angle are used, there is no loss due to reflection and high transmittance can be obtained.
· Because Pellin-Broca prisms are not coated, they can be used with high energy pulse lasers.
· Used by aligning the YAG basic wavelength (invisible light) subjected to the prism or the angle (Brewster's angle) at which the light amount from the second-harmonic beam (green) is the smallest.
· Convert so that the polarization direction of the laser beam is parallel with the bottom of the prism.
· It can also be used for spectroscopy of Ar lasers with multiple wavelength oscillation.
· * Emitted beams with UV wavelengths are outside Brewster's angle, causing reflection.
· * Can be used as a non-polarizing light dispersing prism, but if light is not incident at Brewster's angle it will not be output at a right angle relative to the incident angle.
· * Spectral diffraction is possible even with incidence of an S polarized laser beam, but there will be a reflection loss between the incident surface and the emitting surface.
· * If fingerprints or grime adhere to the non-coated surface, total reflection or non-reflection will no longer be effective.
· * During use, make sure that nothing makes contact with the non-coated surfaces.
· * The actual measured A and B dimensions include chamfering and are slightly shorter.
· * Dimension tolerance is defined by the intersection position of each surface excluding chamfering.
