M-Scope type GSynos

UNDERFILLED LAUNCH OPTICAL SYSTEM

Possible to control underﬁlled launch condition such as N.A., diameter of input light. Best for evaluation of multi-mode optical device.

M-Scope type G is underﬁlled launch optical system, possible to control launch condition
such as N.A., diameter of input light by specially designed optical method. As M-Scopetype G has camera system for observation, it is possible to observe the launch lightposition and launch condition directly. It is widely applicable for optical characteristic
evaluation and measurement of MMF, POF, polymer waveguide in OPCB substrate, andvarious multimode devices and modules. Additionaly, in combination with SYNOS' NFP
and FFP measurement system, EF/EAF measurement system, highly advanced opticalcharacteristic evaluation of various multi-mode device will be realized.

M-Scope type ML

MODE-SELECTIVE LAUNCH OPTICAL SYSTEM

Possible to control launch condition by speciﬁed mode and N.A. Best for evaluation of multi-mode optical device.

M-Scope type ML is mode-selective launch optical system, possible to select speciﬁedangle (N.A.) component of launch light to the sample ﬁbers by specially designed opticalmethod. As M-Scope type ML has camera system for observation, it is possible toobserve the launch light position and launch condition directly. It is widely applicable for
optical characteristic evaluation of MMF, POF, polymer waveguide, and various multimodedevices and modules under controlled launch condition. Additionaly, in combination withSYNOS' NFP measurement system, FFP measurement system, EF/EAF measurement
system etc, highly advanced optical characteristic evaluation and measurement ofvarious multimode device will be realized.
【Features】○Evaluation of various multi-mode device by changing launch condition●Select speciﬁed angle (N.A.) component of launch light to the sample ﬁbers.

diameter●Underﬁlled launch
Underﬁlled launch optical system is the special launch optics thatchanges the spot size and iraddiation N.A. (Numerical Aperture) oflaunch light, and analyze the optical diﬀusion of multimode opticalﬁber, plastic optical ﬁber, etc. Image of underﬁlled launch method
is shown above. In case of underﬁlled launch, sample ﬁber islaunched by all the light ﬂux as speciﬁed N.A. In this case, beam
proﬁle of launch light on sample ﬁber core has ﬂat shape.

In case of mode-selective launch, sample ﬁber is launched by
the light ﬂux of only the speciﬁed N.A. In other words, modeselective launch optics generate the launch light that has thespeciﬁed incident angle only. Image of mode-selective launchmethod is shown above. Launch light has only speciﬁed N.A.
light ﬂux (speciﬁed incident angle light ﬂux), launch light has
ring condition incident angle light ﬂux.
