Summary
SM2802 is a low-cost and derivative scanning system from SM2800 and it also has no torsion bar. The galvo design of SM2802 uses our proprietary technology and it is a little different from that of SM2800 although the shape of SM2802 is almost same as that of SM2800.
The speed test using ILDA 30K test pattern shows that SM2802 can be tuned up to 30Kpps@㊣ 20∼and 38Kpps@㊣ 15∼, which are about 10%-15% lower than that of SM2800. SM2802 is a good choice for those who has a very tight budget for SM2800.
