Standard BTO Crystal Products

Refractive Grade BTO:
(Fully electric poled with single domain)
3x3x3 mm, 2-4 faces polished
5x5x5 mm, 2-6 faces polished
Substrate grade BTO:
(poled, but with domains)
5x5x1.0 mm, <100> or <001> Orientation
   1-2 sides polished
10x10x1.0 mm, <100> or <001> Orientation
   1-2 sides polished
 

BTO crystal must be stored in temperature above 10 °C to avoid phase transition which will cause twin or domain inside crystal
