Refocusing and Collimating Fiber/Lens Objectives
Refocussing & Collimating Fiber/Lens Objectives can be used with polycrystalline fiber cables (4-18 μm spectral range) and chalcogenide fiber cables (1-6 μm spectral range).
Key Features
- Compatible with SMA-terminated fiber cables
- NA=0.35, pupil diameter 15 mm
- Refocusing or collimating design
Applications
- Focusing of collimating beam into the fiber
- Collimation of output beam from a fiber
- Fiber end imagination to detector/emitter element
