摘要：
A modified Bridgman-Stockbarger crystal growth system has been designed and fabricated for relatively low-temperature (up to 250-degrees-C) nonlinear optical organic materials. The novel feature is that the crystal melt surface can be viewed from any direction and the temperature gradient between the hot and cold zone can be adjusted at any time. The ampoule can be lowered at a rate as slow as 0.1 mm h-1. The temperature can be maintained to a precision of +/-0.1-degrees-C. High-quality single crystals of benzil have been successfully grown using this system.
