1.Introduction:
    "Jslsoft Optic Lab" is a on-limits Optic experiment simulation software for teachers and students of high school in physics education.
Special to other common CAI software of physics education,"Jslsoft Optic Lab" is not simply to display some ready-made experiment in computer,It provides a experiment environment filled with optic instrument,you can make optics experiment which you design by yourself freely. "Jslsoft Optic Lab" provides optic instruments such as quadrate medium,triangle medium(prism),ideal diverging lens,ideal converging lens,convex mirror,concave mirror,plane mirror,light and so on. With this instrument,you can easy to make some experiment like reflection of mirrors,refraction of medium,dispersion of prism,whole reflection of medium,converging or diverging of lens and so on.The software can display the whole physics proceed specially for you. it is a useful physics education tool currently.

3.The basal operation
  The generic process for operation:
  First, you create a new experiment.Then you can placed any instruments on the work-area as what you want.Run it,you can get the result.
  The operation of placing the instrument:
  Choose the instrument in the tool box,then place it on the work-area.
  How to adjust the properties of the instruments: 
  You can directly adjust it on the work-area or click right-button to select the 'Property' item.You also can select the main menu item named 'Edit',then choose the child-item named 'Property'.
  How to delete the instruments:
  Choose a device,then click right-button to select the 'Delete' item or select the child-item named 'Delete' owned by main menu item named 'Edit'.

4.The special explain:
  Because the same medium's refractive indexs for different color lights are different,but in this software mediums(such as square-model mediums,triangle-model mediums) owns only one property named 'refractive index',we use a property of light to solve the problem.For example,a quadrate medium's "refractive index" is 1.5,and a light's  "multiple of refractive index" is 1.1, So the quadrate medium's refractive indexs for  the light is 1.5*1.1=1.65.
