Infrared spectroscopy is one of many common analytical methods used for the detection and measurement of atmospheric pollution.

Much of the fundamental research on atmospheric pollution used spectroscopic techniques, as this technology helps us to comprehend various threats to both public health and the environment.

MID-IR Refocusing Objectives  are designed to refocus the beam from the IR-fiber or into the fiber.

The housing of the objective easily connects to fiber optic cables either with FC/PC or with SMA connectors and enables the alignment of the lens position along the Z-axis.

Mid-IR Refocusing Objectives are available with antireflection (AR) coating for two spectral ranges:

3-5µm – for chalcogenide fiber cables.

8-12µm – for polycrystalline fiber cables.

We offer two types of MID-IR fiber refocusing objectives with following lens diameters:

Ø 15mm - F-L

Ø 5mm - F-S
