- Material: 303 stainless steel
- Surface treatment: pickling and passivation
- Eccentric rotating lever with knurled pattern
- Adjustment range: ±0.8mm, ±1mm
The LBTEK eccentric adjustment lever is used to adjust fiber optic couplers. By rotating the eccentric adjustment lever, the adjustable focusing part of the coupler can be moved. Currently, there are two models of eccentric adjustment levers available: 85EK-08 and 10EK-10, with adjustment ranges of ±0.8mm and ±1mm respectively. The 85EK-08 eccentric adjustment lever is suitable for the three-axis FP3 series, while the 10EK-10 eccentric adjustment lever is compatible with the focus-adjustable ADFC series.
