CSJ-30 30mm Threaded Cage Plate

Price range: $16.00 through $25.20

Product Description

Enables direct mounting of optical components in 30mm cage system assemblies;
Features standard SM1 threads (1.035″-40) for Ø1 inch optical elements;
Available with standard SM1, C-Mount or RMS threads;
The CSJ-30/CSJ-R30 models come with 2 retaining rings for mounting Ø1 inch optical elements;
Rods can be mounted via M4 threaded holes.

Cage plates are the basic building blocks for constructing cage systems. The center of a cage plate is typically equipped with a threaded or smooth hole, which is used for mounting optical elements or lens sleeves.

Technical Description

(1) A cage system consists of a variety of precision-machined building blocks, facilitating the flexible construction of large opto-mechanical systems and achieving accurate alignment. Cage plates serve as the fundamental building blocks of cage systems, with a threaded or smooth hole at the center for mounting optical elements or lens sleeves.

(2) The SM1 (1.035″-40) threaded hole at the center of the CSJ-30 and CSJ-R30 cage plates is compatible with Ø1 inch lens sleeves. Comes with 2 SM1 retaining rings, allowing direct mounting of Ø1 inch optical elements with a maximum thickness of 4.7mm. The CSJ30-C can be mated with camera lens assemblies with external C-Mount threads, and the CSJ30-RMS can integrate RMS-threaded components such as microscope objectives into 30mm cage systems.

CSJ-30	CSJ30-RMS	CSJ-C	CSJ-R30
SM1 (1.035″-40)	RMS (0.800″-36)	1.00″-32UNF (C-Mount)	SM1 (1.035″-40)

(3) A setscrew is located on the side of the through hole for fixing cage rods, which can be tightened with a 1.6mm/2.0mm hex wrench. In addition, Ø12mm stainless steel rods can be mounted through the M4 threaded hole at the bottom.
