KTPcrystal

VLP-5 are visual fault locating tools for detecting and highlighting breaks, tight bends, splices or defective connectors on optic fibers. They are perfect complementary and handy tools to OTDRs for their visualized detecting method in close range like OTDR dead zones and high-fiber-count environments.

Beta barium borate(BBO) crystal is one of the best non-linear optical crystals with high effective nonlinear optical coefficient, high damage threshold, wide phase matching range and high deep UV transmittance.BBO is a negative uniaxial crystal, and its o-ray refractive index (no) is larger than the e-ray (ne) refractive index.These features of nonlinear BBO crystal includes wide transparency and phase matching ranges, large non-linear coefficient, high damage threshold and excellent optical homogeneity.
