Integrates FiberPort and LaserPort Products into 30 mm Cage Systems
Allows Stable Fiber Launch Solutions for Cage System Applications
Directly Compatible with Our Ø1" Lens Tubes
Mounting Screws for FiberPort are Included
8-32 (M4) Tapped Hole for Post Mounting

The CP08FP(/M) is designed to center a FiberPort or LaserPort inside a 30 mm cage system. It features enhanced cage-rod flexure clamps that are designed to securely hold the cage plate in position for greater stability of the FiberPort system. ER rods can be inserted into the four holes provided in the adapter as shown in the family image above. In addition, the four 2-56-threaded, 1/4"-long stainless steel socket head screws necessary to secure a FiberPort to the adapter are included. The cage plate contains an internal SM1 (1.035"-40) threading, enabling it to be used with our extensive line of Ø1" lens tubes. A bottom-located 8-32 (M4) tap is provided for post mounting.

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 to right). 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.

Standard Cage System Measurements
Cage System	16 mm	30 mm	60 mm
Thread Series	SM05	SM1	SM2
Rod to Rod Spacing	16 mm (0.63")	30 mm (1.18")	60 mm (2.36")
Total Length	25 mm (0.98")	41 mm (1.60")	71.1 mm (2.8")

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.
	30 mm
	60 mm
Optic Mounts	16 mm	Thorlabs offers fixed, kinematic, rotation, and translation mounts specifically designed for our Cage Systems.
	30 mm
	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.
	30 mm
	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. Explore our Cage Systems Visual Navigation Guide to see the full range of Thorlabs' cage components.

Response from Buki at Thorlabs: The CP02FP/M (metric version) is similar to the CP02FP (imperial version) except that the metric version has an M4 mounting hole at the bottom while the imperial version has an 8-32 mounting hole. If you don’t need to mount the cage plate to a post, the metric version will work well as a substitute.

I was trying to order a PAF-X-2-A with a CP02FP. Since this plate adapter isnt available and would be shipped separately, I checked CP02FP/M, which is available. According to the drawings its identical but for a "metric" mark. I dont dare order it because I dont want to end up with an adapter I cant use and still having to order the other type separately. Are these two really the same (but for the mark)?
