In the innovation development environment of Chinese Academy of Science (CAS) technology industry, to meet the technology industry development of Shanghai Institute of Optics and Fine Mechanics technology, CAS, southern industrial park of Shanghai Institute of Optics and Fine Mechanics was established in September 2004 by integrating parts of institute’s technology industry.
Industrial park located in southern development zone of Jiading District (Zhaoxian Road 200), Shanghai, covering 23.7 mu, with the construction area of 6200m2. The park gathered Crystal Material Dept and Solid-State Laser Dept of Shanghai Daheng Optics and Fine Mechanics Ltd, Shanghai Power Equipment For Laser Co., Ltd, Shanghai Leo Laser Equipment Co., Ltd., Shanghai Forward Optoelectronics Co., Ltd. The main products involved in optical crystal material, solid lasers, high-pressure constant current DC powers (electrostatic dust abatement), high-power CO2 lasers, laser processing, laser diode and its components in series.
Southern industrial park building marked a new development starting of institute technology industry. Every enterprise will focus on the future development from new starting point and new level, face up to the current increasingly fierce market competition, and make a greater contribution to our institute development.
 
 
   
   
 
 

Now, we have two series and three types of infrared transmitting glass. The first one is pure fluoride glass series, and the second is fluorine oxide glass series, material performance as follow:

Pure fluoride glass series:
1. fluorine aluminate infrared transmitting glass:
(1) transmission range:0.35~7mm, permeance ratio between 0.42~5.2um greater than 90%(3mm samples)
(2) optic capability: refractive index nD=1.426, Abbe number Vd=97
(3) chemical stability: resistance to moisture A level, resistance to acid 3 level (according to GB903-65), no obvious corrosion mark after 24 hours’ soak in water
(4) thermal capability: softening temperature 450 °C, coefficient of thermal expansion (20-120)14.7*10-7/
(5) mechanical capability: elastic ratio 70.2GPa, microhardness 360kg/mm2
(6) the maximum size provided: f100*4mm

Fluorine oxide glass series:
1. fluorine aluminate-Te infrared transmitting glass:
(1) softening temperature 420~435, other characters like fluorine aluminate infrared transmitting glass

2. fluorine germanate infrared transmitting glass:
(1) transmission range:0.32~5.5mm, permeance ratio between 0.45~4.5um greater than 85%(5mm samples)
(2) optic capability: refractive index nD=1.6~1.69, adjustive according to requirement
(3) thermal capability: softening temperature 452~570
the maximum size provided: f300*20mm, can provide bigger size and special shapes product according to requirement
