KCD1L-M1 4-40 Thread 30mm Cage Type 90-degree Right Angle Bracket for Optics Experiment Components

Description:
Figure A:
- The right-angle adjustment bracket is compatible with Ø1" (25.4mm) optical elements, providing the largest clear aperture for transmitted light, and providing space for operating installed optical elements. The rear-mounted design does not limit the thickness of the optical components to be installed. Even if the mounting base is equipped with a cage rod or a lens tube, the installed optical components can still be operated. Teflon gaskets can be used to install optical components with a thickness of less than 3mm, which can protect the lens (sold separately).
- The adjustment screw can be used to pitch and tilt the surface plate. The screw can ensure smooth and highly sensitive movement with a resolution of 0.01 inches (0.254mm). Two of these adjusters come with manual knobs, while the other must be adjusted using a 5/64 inch (2mm) hex wrench or balldriver.

Figure B: One M4 screw hole and one M6 screw hole (for Ø12mm and Ø1 inch post).
- An optical element installed at a horizontal angle of 45° provides adjustable pitch and tilt. The port is different from the KCD1L-M through-hole design. The KCD2L-M adopts the American-made 4-40 threaded hole design. Directly install the screws and screw it on, the stability will be more stable than the through-hole design. Their spacing matches our 30mm cage system standard. This design allows multiple 30mm cage components to be directly connected without the need for cage rod adapters.

Figure C: The diameter of the lens hole is 1 inch, SM1 thread. Compatible with SM1 lens tubes.

Features:
- The KCD1L-M1 right-angle adjuster design is easy to fit into our 30mm cage system. The entrance and exit ports of the mount have an SM1 screw hole that can be integrated with a Ø1" lens tube.
- KCD1L-M1 is used to fix M6 cage rod with American 4-40 screws, the stability will be more stable than the through hole design.
- M4 screw hole on the bottom and M6 screw hole on the top are used for Ø12mm and Ø25mm posts.
- Reflective lens of Ø1 inch (25.4mm) can be installed at 45° relative to the optical axis.
- Adjustment range: ±4°pitch and tilt adjustment.
- Compatible with 30mm cage system and SM1 (1.035''-40) thread.
- The lens hole diameter is 1 inch, SM1 thread, compatible with US-made SM1 tube.

Optical commonly used thread size standard:
- This is the unique thread for Thorlabs in the United States, not the commonly used optical thread. SM is the code for the thread of the sewing machine in terms of thread expression, but this company in the United States uses it to connect the internal and external threads of the optical lens and the sleeve. The nature of the thread is UNS, and the United States has a special thread with a tolerance accuracy of 2A/2B. The special place of this thread is 40 teeth per inch regardless of the diameter.

Package Included:
