FIS4-Far-Infrared-C

Four-wave Interference

Application:Laser beam wavefront detection, adaptive optics, optical system calibration, gas and plasma density measurement, internal lattice/homogeneity measurement of materials, and wavefront measurement of metasurfaces and metalenses.

Equipment advantages

◆ 100% domestically developed

◆ Single-path light self-interference, no reference light required

◆ 8μm~14μm (center band 10.6μm) band

◆ 15nm RMS high phase resolution

◆ Large dynamic range up to 260μm

◆ Extremely strong vibration resistance, no need for optical vibration isolation

◆ With laser interference fringe suppression design

◆ Support collimated beams and large NA converging beams

100% domestically developed, with ultra-high resolution of 160×128 (20480) phase points, it can achieve high-precision wavefront measurement in the 8μm~14μm (center band 10.6μm) band, which can be used for Laser beam wavefront detection, adaptive optics, optical system calibration, gas and plasma density measurement, internal lattice/homogeneity measurement of materials, and wavefront measurement of metasurfaces and metalenses, etc.

FIS4 FIR combines the patented random coded four-wave diffraction technology with an infrared camera to interfere at the rear image plane position. It has low requirements for light source coherence and does not require phase shifting. Ordinary imaging systems can achieve interferometric measurement. It has ultra-high vibration resistance and ultra-high stability, and can achieve nm-level precision measurement without vibration isolation.
