About this product
Part Number: 19390
The Optec #19390 Variable Length Camera adapter makes setting your camera at the perfect back-focus distance quick and easy.
With an OPTEC-2100 base to fit the Lepus or NextGEN telecompressor and T-thread camera interface, The #19390 VLC can set the back-focus from 25 to 42mm. Refer to the back-focus diagram for your NextGEN or Lepus telecompressor lens to determine the optimal back-focus distance.
Each VLC adapter has a precision engraved scale showing the distance in millimetres from the T-thread or STL-thread seat to the base of the adapter. When calculating the back-focus distance for your telecompressor and camera setup, use the engraved scale to set the correct distance remaining after subracting for the camera sensor depth, filter wheel thickness, OAG thickness, etc. With the included locking ring, sub-millimetre precision can be achieved for setting the camera back-focus to telecompressor distance exactly at the optimum location.
The VLC adapter is available with T-threads only.
