This Lepus Camera Adapter/ Mount/ Extension Tube is Camera-Specific for the Lepus Telecompressor.
- Length: 23 mm
- Mechanical Interface: T-thread.
- Flange Thickness: 2.5 mm
The Lepus telecompressor has a design back-focus distance of 100 mm on-axis. Each of the camera mounting plates are designed to maintain that back-focus for the best overall image quality and a reduction of 0.62X. Varying the back-focus distance will alter the magnification (reduction) but may introduce undesirable optical aberrations as well. The manufacturer recommends using the Lepus telecompressor only with the recommended camera-specific mount.
Each camera mount consists of a 2.1-inch ID tube of various lengths and a mechanical interface such as a T-thread, C-mount, or STL thread. This ID tube fits over the camera side of the Lepus telecompressor, which features the OPTEC-2100 male circular dovetail mount. The camera mount is held securely to the Lepus dovetail using three oval point setscrews located 120 degrees apart.
It is important that the overall back-focus distance be set as closely as possible to the design distance of 100 mm on-axis. Measured from the flange at the bottom of the OPTEC-2100 dovetail, the distance works out to 105 mm as shown in the PDF at left.
Most of the mechanical camera interfaces require an additional 1/10th inch or 2.5 mm of back-focus. The camera backfocus distance, BF, should be known to within about 1 mm for best performance and should include the thickness of any filter wheel, off-axis guider or other adapter between the Lepus and camera sensor. Use the table below to find the appropriate mounting plate for many commercially available cameras and configurations. If your camera is not listed below and you know the optical back-focus, BF, and mechanical interface (i.e. T-thread) you can determine the stock number as with the following calculation:
This adapter is:
- Length: 23 mm
- Mechanical Interface: T-thread.
- Flange Thickness: 2.5 mm
If you require another connection or length, you can contact OPT -by chat, email, or phone) and we can have the correct match made for you. (The other connections are: Pentax Thread, SCT thread, STL 2.156-inch thread, and C-mount. Also, Canon and Nikon DSLR requires T-thread and brand specific bayonet mount.)
