DescriptionProduct DescriptionReduces mechanical stress on optical components during clamping;Provides light sealing around optical components;Compatible with sleeve series or optical-mechanical components with SM05, SM1, and SM2 threads;Different from ordinary retaining rings, the stress-free retaining rings are equipped with rubber O-rings, which effectively reduce stress on the surface of optical components and avoid performance degradation or damage caused by mechanical pressure.ModelSpecificationExternal Thread TypeWeightCSF05Ø13.5*3.5mmSM05 (0.535”-40)0.4gCSF1Ø26.1*3.5mmSM1 (1.035”-40)1.1gCSF251.6*4.7mmSM2 (2.035”-40)5.1gTechnical Description(1) Unlike ordinary retaining rings, the stress-free retaining rings come with rubber O-rings, which effectively reduce stress on the surface of optical components, preventing performance degradation or damage caused by mechanical pressure. They also achieve light sealing to avoid interference from stray light.（2）The retaining rings support multiple standard thread types, including SM05 (0.535″-40), SM1 (1.035″-40), and SM2 (2.035″-40), and are suitable for threaded adjustment frames, lens sleeves, and adapters without installed optical components. (3) The stress-free retaining rings are designed with two grooves, compatible with standard retaining ring wrenches for easy installation and disassembly, improving operational efficiency.AssemblyApplication ExamplesEngineering DrawingCSF05 Engineering DrawingCSF2 Engineering DrawingCSF1 Engineering Drawing
