BBO Crystals
 is a nonlinear optical crystal which combines a number of unique features. These features include wide transparency and phase matching ranges, large nonlinear coefficient, high damage threshold and excellent optical homogeneity. Therefore, BBO provides an attractive solution for various nonlinear optical applications.

BBO crystals is also an excellent electro-optic crystal for high power applications at the wavelength range from 200nm to 2500nm. It can be used for Q-Switching in a CW diode pumped Nd:YAG laser with average power>50W.

High Temperature form BBO ( a -BaB 2 O 4 ) is a negative uniaxial crystal. It has large birefringence over the broad transparent range from 189 nm to 3500 nm. The physical, chemical, thermal and optical properties of a-BBO crystals are similar to those of b-BBO. However, the nonlinear optical properties of a-BBO crystal is vanished due to the centric symmetry with its crystal structure. It is not recommended to use for NLO processes.

A-Star focuses on the development and production of optical Lenses, telescopes and photo-electrical instruments. Focusing non the innovation, inspire in the future, A-Star’s optics use the most advantage technology,

Plano Convex Lenses

Plano-convex Lenses present a curvecd interface and a planar interface. Thay are for instance the microlenses situated on top of a wafer, and also encountered in macroscopic optical systems

Zero Order Waveplate

zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. Zero order waveplate shows better performances than multiple order waveplates, it has broad bandwidth and a lower sensitivity to temperature and wavlenght changes. It should be considered for more critical online_orderings.
