{"title":"SM2 Lens Tube","description":"LBTEK lens tubes are commonly used to secure optical components with a diameter of Ø50.8 mm or to block stray light in optical paths, preventing environmental light from affecting the system. LBTEK's SM2 lens tubes come in three versions: with both internal and external threads (SM2-xxA), internal threads only (SM2-xxB), and external threads only (SM2-xxC). The lens tubes can be combined to extend their length, facilitating the rapid setup of compact optical systems. By using a retaining ring wrench, the retaining ring can be positioned at the desired location inside the lens tube to separate and secure optical components.\n\nIn addition to the standard SM2 lens tubes, LBTEK also offers SM05 and SM1 lens tubes, along with compatible accessories such as lens tube adapters, retaining rings, and retaining ring wrenches.","products":[{"product_id":"sm2-lens-tube-sm2-75a","title":"SM2 Lens Tube SM2-75A","description":"\u003cp\u003e\u003cstrong\u003eSM2 Lens Tube\u003c\/strong\u003e — Model SM2-75A\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #16a34a;\"\u003e✔ In Stock — Ships Today\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cdiv class=\"wq-pdp__lbtek-desc\"\u003eThe LBTEK internal and external threaded lens sleeve features SM2 external threads on one end and SM2 internal threads on the other, primarily used for securing optical components with a diameter of Ø50.8 mm.
