Click Here to See How to Use the Multi-Element Tube System Components to Build an Optical System.

TECHSPEC® Multi-Element Outer Tubes provide a compact and contained system mounting solution. Available in five different lengths, these outer tubes allow for control of overall system length. The enclosed design and matte finish helps prevent unwanted external and stray light from entering the optical system. TECHSPEC® Multi-Element Outer Tubes feature M29 x 0.75 internal threads along the entire optical axis, allowing for infinite optical spacing adjustment for both TECHSPEC® Multi-Element Inner Single Optic Mounts and TECHSPEC® Multi-Element Inner Pair Optic Mounts. For harsh environment applications, the Multi-Element Retaining Ring Set (#37-774) is highly recommended to lock in lens spacing.

Note: The TECHSPEC® Multi-Element Tube System Accessories are recommended for easy system expansion or integration. The Multi-Element 2" Square Cage Interface Plate (#11-213) can be used to mount a Multi-Element Tube System Assembly to a TECHSPEC Stainless Steel Mounting Post.
