Glad to know you from your website,that you are the leading company in Japan for machine vision system. （后面再追一句概述他的业务性质，特色等的话，表示你对他们慎重研究了。比如：I just notice that you pay much attention to lower your cost for quality machine vision system. ) 

This is ***company here. （这句话有些生硬，过渡不自然，缺少人情味。May I introduce myself to you ? I am XXX, from XXXX. 这样会更人情味点。） I am sure we are the right one for you to seek vision solution, Industry information,customizing products on your request.（这后面一句太突然，没有过渡。） 

Maybe (这个词没有力度，不自信，犹豫不肯定） we can help you to save at least 10% cost saving with more high quality service. 

Some of our new models,such as Machine vision Lens/ Bi-Telecentric Lens /HD XGA Industrial Cameras,have a bright （有点歧义，不如就用good,注意用最简单的英语，日本人英语不好。） market at home and abroad.

Could you please do me a favor to tell me what items are more salable for you? （这句有点突然。）

由于实际情况不一样，不一定就合用，贴这个例子，是希望大家通过对实际案例的运用，来了解开发信应该如何写，只看理论会让人有点迷糊。
