High contrast Far-Infrared and Mid-Infrared Polarizer P03
High contrast polarizer for the far-infrared and complete mid-infrared simultaneously. High-frequency limit is extended to typically 5000cm-1 or 2μm. A polarization contrast of Tp/Ts = 10,000 : 1 is reached.
Very high degree of polarization P = (Tp - Ts)/(Tp + Ts) > 99.99%
Thin, compact, rotable
Wide wavelength range > 250μm to 2μm (equivalent to 40 ..... 5000cm-1)
Complete and continuous mid-ir to far-ir-coverage
No substrate - there is no beam deviation and no substrate dependent dispersion
Ideal for 1.2 to 150THz spectroscopy
Standard clear apertures: 13 and 25mm diameter, new: 18.4mm
Application: THz-, fir-, mir-spectroscopy, polarimetry, ellipsometry
The polarizer is mounted in a 50 (33)mm dia. x 14mm thick metal ring. Four 2mm dia. screw holes on a 38 (24)mm dia. circle are provided for mounting.
New: the 18.4mm diameter CA is mounted in 25.4mm diameter ring with 2.5mm thickness
Please see below the typical extinction and transmission spectrum (against linearly polarized light as reference):
High contrast Infrared Polarizer P02
Free-standing grid array polarizer for the far-infrared and mid-infrared. Patented design extends high-frequency limit by one order of magnitude to typically 2500cm-1 or 4μm. A polarization contrast better than Tp/Ts = 10,000 : 1 is reached.
Very high degree of polarization P = (Tp - Ts)/(Tp + Ts) > 99.99%
Thin, compact, rotable
Wide wavelength range > 300μm to 4μm (equivalent to 30 ..... 2500cm-1)
Continuous mid-ir to far-ir-coverage
No substrate - there is no beam deviation and no substrate dependent dispersion
Ideal for 0.9 to 75THz spectroscopy
Standard clear apertures: 25mm, 40mm and 100mm diameter
Application: THz-, fir-, mir-spectroscopy, polarimetry, ellipsometry
The CA 25mm polarizer is mounted in a 34.8mm dia. x 8mm thick metal ring.
Please see below the typical extinction and transmission spectrum (against linearly polarized light as reference):
High contrast Broadband Millimeter-Wave and Far-Infrared Polarizer P01
Highcontrast grid array polarizer for the far-infrared and millimeter-wave region. A polarization contrast better than Tp/Ts = 10,000 : 1 is reached.
Very high degree of polarization P = (Tp - Ts)/(Tp + Ts) > 99.99%
Thin, compact, rotable
Continuous millimeter-wave to far-ir-coverage
No substrate - there is no beam deviation and no substrate dependent dispersion
Wide wavelength range > 2.5mm to 12μm (equivalent to 4 ....... 800cm-1 or 120GHz ....... 24THz)
Standard clear apertures: 25mm, 40mm and 100mm diameter
Application: THz-, fir-, mir-spectroscopy, polarimetry, ellipsometry
The CA 25mm polarizer is mounted in a 34.8mm dia. x 8mm thick metal ring.
