The Cedar Oil Color Corrector :)

Posted By Arkady Vodyanik

Here is an explanation:

I love APO as idea smile And I am very interested to do somewhat in this area. Of course, I know something about Rolando's and Valery's correctors.

Here is known Chinese refractor: achromat, 127 f/9.5:










And now it will be improved due my own correcor smile !!!
It consists only of usual glasses (BK7/F2) ... and the CEDAR OIL is between them.










We obtain almost visual apo with the small field. Field easily increases due to the small loss of quality on the axis. The strong dependence of the coeff. of refraction of oil on the temperature here (in my view and calculation) is shown weakly. Thanks for attention and critics!

LINZIK Version 0.81 - May 18, 2008:
http://www.linzik.com/download/linzik_0_81_Eng_Setup.exe

What's new:

1) Corrected the bug - versions 0.7 and 0.8 were not working in
Windows x64.

2) The [nv_ ...] functions use not CUDA 1.1 but CUDA 2.0 BETA for
compatibility with Vista. If you intend to use these functions then
download a new version of a suitable driver: http://www.nvidia.com/
object/cuda_get.html
