Sine Scientific Instruments


Sine Scientific Instrument is a brand belonging to Guangzhou Sine Scientific Instruments Company.

Sine Scientific Instrument is a brand belonging to Guangzhou Sine Scientific Instruments Company.

Mission: To create cost-efficient scientific instruments, to provide professional and reliable technology service! 

Belief: Modesty and perseverance for the best! 

Group: Mostly with a doctor degree and diverse application backgrounds in microelectronics, physics, optics, etc., our group members have rich and professional experience in integrated circuit design, electromagnetic compatibility analysis, digital signal processing, etc., for more than ten years. 

Region: Researches on theories and applications of weak signal detection. 

Objective: To create the best measurement instrument on weak signal detection in the world! 

Technology: Our group have used many advanced analog and digital technologies in our product, such as low-noise pre-amplifier of lock-in amplifier(LIA), signal integrity solution in low frequency, electromagnetic field shielding in low frequency, accurate digital signal processing high up to 64 or 128 bit precision, low-noise high order filter technology with high stability, etc. 

Facility: SYSU National Level Experiment Teaching Center for Physics, SYSU State Key Laboratory for photoelectric material and technology, SYSU National education base for microelectronics and integrated circuit talents, Guangdong integrated circuit engineering center, etc. 

Management: Our group members is educated with high standard on product researches and manufacture, which is based on Huawei quality management system. From component procurement, storage and transportation, PCB fabrication to SMT and product testing, each process on product fabrication is strictly controlled and highly required to ensure the high quality of our product. 

Landmark: In 2003, we launched our first analog LIA for near-infrared optical filming. In 2007, our first digital LIA was rolled out. A year later, we made our first educational digital LIA. In 2011, we launched our first advanced digital LIA, the OE1021, with a large-size color LCD screen and a digital processing core made of both FPGA and ARM. In 2012, we got the classic LIA, the OE1022, and the optical chopper, the OE3001, out. Especially, the OE1022 covers all the functions of the SR830 and gets a better performance than the SR830 in some qualifications. In 2014, we made a 3M LIA, the OE2031. In 2015, we minimized our LIA and made a small LIA, the OE1201 and a two-channel LIA, the OE1002D.

Future: We are aiming at a larger bandwidth LIA, a special and mini LIA component for applications on extreme environment or special circumstances and relevant photoelectric products.
