新的消色差改正镜Raycorr LT3,有听说吗?

以前的消色差改正镜叫 Chromocorr,1代和2代.

现在ISTAR公司又在研制Raycorr LT3和Raycorr Pro6,

现在没价格, 可能分别$300和$600

目前没有进一步的消息, 只有ISTAR公司给用户的回复:

随时关注进展:

"we are working on two separate versions. Raycorr LT3 will be 3 element corrector
strictly for visual use and we strive to get a near APO performance with limited FOV.
The Raycorr Pro6 will be 6 element Fluorite Glass and Lanthanum glass combo,
we are also looking into possibility of integrating CaF2 element into this design.
Such design will be substantially more expensive over the LT3 version but it should
turn any achromatic doublet into a Photo APO system limited to about 16x16mm chip size.
In the future we would like to create version for even larger chip sizes but not sooner as 2013.
These correctors will be produced for the following F/Stop ranges
F5 to F7,9
F8 to F/9,9
F10 to F15

we are way behind with this design, we hope to introduce first units by end of this year or beginning of 2012.
Have a great day, talk to you soon,
best regards,
