PrimaLuceLab
PL3304805

PrimaLuceLab M48 extensions are available in different lengths and they present on both sides of a M48 thread (one side is male, the other is female). Completely made of metal with black anodizing (both internal and external), these extensions offer an external knurling for a better grip (very useful for example when screwing or unscrewing). Thanks to different M48 extensions and spacers, by ordering different combinations you can adjust the thickness of your personalized extension, in 0.5mm steps!

M48 extension rings have different use:

  1. can be screwed to optical accessories (such as field flatteners or focal reducers) to bring the camera sensor at the right distance from the lens (to optimize performance)
  2. can be used to separate the mechanical accessories that, when used together, can touch and then not work properly (eg an off-axis guider could touch a filter wheel and it could prevent its rotation searching for a guide star)

 

 

5mm M48 extension

M48 extensions can be screwed together. In order to set the perfect thickness you need, you can also add the M48 1mm and 0.5mm spacers in between.
