Thorlabs' Mini-Series Posts are designed to facilitate the integration of our Mini-Series components and accessories into optomechanical setups within a limited space. These posts are designed for compact and OEM-level optomechanical assemblies. Each post includes a 4-40 (M3) setscrew and features top- and bottom-located 4-40 (M3) tapped holes. For compatibility with our standard optomechanical components, we offer post thread adapters to convert among 8-32, 4-40, and 1/4"-20 imperial thread types as well as the M3, M4, and M6 metric thread types. In addition, we offer the HW-KIT5(/M) 4-40 (M3) screw kit, available below, as well as 8-32 (M4) and 1/4"-20 (M6) screw kits for the hardware needed to assemble Mini-Series and standard optomechanical components.
Our Mini-Series Post Holders, which are directly compatible with our Mini-Series Breadboards, can be used to mount our Mini-Series posts while allowing for height adjustment. Alternatively, we also offer Mini-Series Pedestal Posts and Clamping Forks. Both types of posts are designed to support our Mini-Series Kinematic Mirror Mounts, Cylindrical Collimator Mount, and Iris Diaphragm.

(posted 2017-03-28 11:20:43.713) Can we use cage system rods instead of mini posts? They seem to have the same measures and threads. tfrisch
(posted 2017-03-29 11:43:24.0) Hello, thank you for contacting Thorlabs. You can use cage rods as mini series posts, yes. cbrideau
(posted 2016-08-31 20:25:18.813) It would be nice to see a version with captive screws like the CF125C. The 4-40 screws are hard to position and handle because they are so tiny. tfrisch
(posted 2016-09-01 02:00:26.0) Hello, thank you for suggesting this. I've posted it in our internal engineering forum. user
(posted 2012-02-23 00:56:56.0) Hi guys. What applications use these mini series posts and mounts? Trying to decide between these and the (less expensive) standard 1/2-in. Post system...also, do you have adapters if I want to use them on a full size breadboard with 1/4-20 holes? Thanks, Lev. acable
(posted 2009-08-12 10:39:58.0) The socket in the thumbscrew for the MSRA90 is a bit to sloppy, this causes the wrench to bind in the socket. acable
(posted 2007-11-04 09:36:41.0) Since this is a "new standard", please consider doing a better job in the main portion of the presentation of pointing out what the new standard actually is, i.e. the post size and threads. |
