HIGH RESOLUTION FFP MEASUREMENT OPTICS FOR IR RANGE M-Scope type FHR
PRODUCT OVERVIEW
M-Scope type FHR is an optical system for measuring FFP in 1310~1550nm NIR spectral range with high accuracy. The combination with VGA Type InGaAs High Sensitivity NIR Detector ISA041VH enables high-accuracy FFP measurement with an angle pixel resolution of 0.1° in 1310~1550nm spectral range.
It can be applied to high precision FFP measurement and N.A. measurement of various optical devices in optical communication fields such as optical fibers, optical waveguides, optical modules, and Si photonics devices.
It is possible to build high precision FFP measurement system in combination with SYNOS' Optical Beam Analysis Module AP013.

SIMPLE STRUCTURE OF HIGH RESOLUTION FFP MEASUREMENT OPTICS FOR IR RESION M-Scope type FHR
As shown in the figure on the left, the light flux, having incident angle θ from the sample, is focused at a point on the detector through f-θ lens, field lens and relay lens module. By this way, FFP image of the sample is formed and acquired by imaging detector, and analyzed directly and quickly by image processing method.
