The LCP360R is easily snapped into and removed from preassembled cage sections, as shown in the animation above. It can be used to mount optics at variable angles of incidence (AOI), as shown below.

Features

  • Quick-Release Cage Mount with Adjustable SM2-Threaded (2.035"-40) Optic Cell
  • Compatible with Ø2" and Ø50 mm Mounted and Unmounted Optics
  • On- and Off-Axis Optic Alignment for use with Mirrors, Beamsplitters, Filters, and Lenses
  • Quick-Release Flexure Clamping Mechanism for Secure Cage Mounting without Disassembly

The LCP360R cage mount allows for 360° of manual rotation of an optic within a 60 mm cage system. Optics up to 8 mm thick can be mounted against a lip at the end of the 11.3 mm (0.45") long SM2-threaded (2.035"-40) optic cell using an included SM2RR retaining ring. The LCP360R mount uses a flexure-style clamp with two 3-48 (5/64" [2.0 mm] hex) cap screw to quickly connect the mount without disassembling the cage. Simply turn the optic perpendicular to the cage system's optical axis and loosen the setscrews enough to allow the flexure mechanism to snap onto the cage rods, as shown in the animation to the right. The LCP360R mount can be attached at any two of the four cage rods for either X- or Y-axis pivoting adjustment. The cage mount can be slid along the cage rods by loosening the setscrews in the flexure clamps.

The optic can be rotated via the knurled knob or 5 mm (3/16") hex, and the optic mount's pivot position can then be locked via a 8-32 (5/64" [2.0 mm] hex) setscrew. An engraved scale indicates the angle of the optic, with tick marks every 5°. Please note that when using with beamsplitters, the clear aperture will be an ellipse with a minor axis of approximately 1" (25.4 mm) when used at 45° AOI. Thorlabs also offers a smaller version of this item for 30 mm cage systems designed to mount Ø1" optics, which can be found here.

Cage System Overview

The Cage Assembly System provides a convenient way to construct large optomechanical systems with an established line of precision-machined building blocks designed for high flexibility and accurate alignment.

16 mm, 30 mm, and 60 mm Cage System Standards

Thorlabs offers three standards defined by the center-to-center spacing of the cage assembly rods (see image below). The 16 mm cage, 30 mm cage, and 60 mm cage standards are designed to accomodate Ø1/2", Ø1", and Ø2" optics, respectively. Specialized cage plates that allow smaller optics to be directly inserted into our larger cage systems are also available.

Standard Threads

The flexibility of our Cage Assembly System stems from well-defined mounting and thread standards designed to directly interface with a wide range of specialized products. The three most prevalent thread standards are our SM05 Series (0.535"-40 thread), SM1 Series (1.035"-40 thread), and SM2 Series (2.035"-40 thread), all of which were defined to house the industry's most common optic sizes. Essential building blocks, such as our popular lens tubes, directly interface to these standards.

Cage Components
Cage Rods 16 mm These rods are used to connect cage plates, optic mounts, and other components in the cage system. The SR Series Cage Rods are compatible with our 16 mm cage systems, while the 30 mm and 60 mm cage systems use ER Series Cage Rods.
30 mm
60 mm
Cage Plates 16 mm These serve as the basic building blocks for a cage system. They may have SM-threaded central bores, smooth bores sized for industry standard optics or to accommodate the outer profile of our SM Series Lens Tubes, or specialized bores for other components such as our FiberPorts.

60 mm
Optic Mounts 16 mm Thorlabs offers fixed, kinematic, rotation, and translation mounts specifically designed for our Cage Systems.

60 mm
Cage Cubes 16 mm These cubes are useful for housing larger optical components, such as prisms or mirrors, or optics that need to sit at an angle to the beam path, such as beamsplitters. Our cage cubes are available empty or with pre-mounted optics.

60 mm
Post and Breadboard Mounts and Adapters Mounting options for cage systems can be found on our Cage System Construction pages. Cage Systems can be mounted either parallel or perpendicular to the table surface.
Size Adapters Cage System Size Adapters can be used to integrate components from different cage system and threading standards.
Specialized Components Thorlabs also produces specialized cage components, such as Filter Wheels, a HeNe Laser Mount, and a FiberPort Cage Plate Adapter, allowing a wide range of our products to be integrated into cage-mounted optical systems.
