14PIR - Broadband mid-IR polarizers
Model:
品牌:Standa

產品特色Features


		Extremely broadband

		Wide acceptance angle

		Polyethylene polarizers for 20-1000 microns are also available!

		Long life time

A fine array of parallel conducting wires whose period is smaller compared to the wavelength of incident radiation will transmit one polarisation and reflect the other. The component of the radiation whose electric vector is perpendicular to the direction of the wires and induces current in the wires will be transmitted and the parallel vector reflected. Mid-IR polarizers are produced by holographic method (i.e. laser interferometry) or mechanically ruled. These polarisers do not suffer from beam displacement, are not affected by diverging or converging beam, have wide acceptance angle without degradation of performance and portable.
