Features:
The coating in this series is named "PTFE",the molding technique of the coating material power die casting.This coating has many advantages like reflectence,wide range of wave,easy to clean,good weather ability and so on.It is acclaimed in the area of the integrating sphere.There are three models now in our company.They are MSPD1-0025,MSPD1-0038,MSPD1-0050(1in,1.5in,2in).
The biggest difference of the sphere between this series and other series is that the interna coating is made of the material striaghtly,and then we install the external shell to it .When doing the common sphere usually we first do the sphere shell and then spray the coating to the internal surface of the shell.So in the structure,the coating is very strong and it never drop out and goes yellow theoretically.When using thesphere,the principle is same as the common sphere.

1) Lifetime of machinery:10years
2) Lifetime of diffuse reflective coating:5years
3) Stability:Room temperatureHigh temperature
4) Humility:20-80%RH
5) Storage Conditiion:RainDust proof
