Collimating & Refocusing Objectives for mid Infra-Red Fiber Cables

Categories: , Tag:

Main features:

  • Compatible with SMA- or FC-terminated fiber cables
  • Pupil diameter 15mm or 5 mm
  • Thread build-in in your optical system
  • Non-Magnetic Aluminium Housing
  • Refocusing or Collimating design

Description

MID-IR Focusing and Collimating Objectives are designed to use with Infra-Red fiber optic cables and bundles.
The housing of the lens easily connects to fiber optic cables either with FC/PC or with SMA connectors and enables Z-axis alignment.

Mid-IR Lenses are available with anti-reflection (AR) coating for two spectral ranges:

  • 3-5µm – for chalcogenide fiber cables
  • 8-12μm – for silver halide fiber cables

MID-IR Refocusing Objectives (FORO)

 

Collimating Objectives for Mid IR-Fiber Cables (FOCO)

Applications

  • Focusing the beam out of the fiber or, used in reverse, into the fiber
  • Collimating the beam out of the fiber or, used in reverse, focusing of collimated beam into the fiber
  • Fiber end/bundle imaging to the detector

Using a lens to collect the radiation into the optical fiber

The area S is limited by the numerical aperture of the optical fiber. The fiber "sees" the radiation exiting from each point within the area S.

The radiation reaching the fiber end is pro

portional to the angle d1/L, where d1 is the fiber diameter, L is the distance between S and fiber end.

To increase the radiation collected i

nto the fiber, it is necessary to put a lens between S and fiber end, then the signal is proportional to d2/L, where d2 is the lens diameter (d2 > > d1).

Focus distance F and the lens diameter d2 should agree with the numerical aperture of the fiber.
