Zulin,

Check out this two lens from Thorlabs:
http://www.thorlabs.com/thorproduct.cfm?partnumber=LJ1516RM-A

http://www.thorlabs.com/thorproduct.cfm?partnumber=LK1002RM-A

Both are 1" round Cylindrical lens.  One has a focal length of  f =1000 mm
and the other f = -1000 mm.  Separate them by 96 mm and you will get
effectively f = 10000mm.

Hope that help.

Regards,

Hongzhou
