Re: [tec-scopes] TEC 140 + FF + QSI 683-8
- Rick,you need to check the QSI website where there is a document reporting all the backfocus lengths for the various QSI models (http://www.qsimaging.com/documentation.html).If I understand correctly, you have the 2.156" faceplate (backfocus 53.34 mm) so you need an 85-53.34=31.66 mm spacer with no filters. Then you need to increase the spacing by 1/3 of the filter thickness. TEC FF specs show that you need to provide the correct 85-mm spacing within +/- 1 mm. I would request 33 mm spacer length at PreciseParts with quite common 3-mm filters. Specifying fractions of mm is useless.Regards,AntonioOn Apr 10, 2013, at 4:46 PM, richardsteele999 <rick@...> wrote:
Hi all! What is the exact spec that I need to give Ashley at precise parts in order to mate my QSI 683 with 8 filter wheel to my TEC 140 with Field Flattener? It's the WS (not the WSG) model.
