OPTICS AND OPTICAL MEASUREMENT INSTRUMENTS
WIDE AREA FFP MEASUREMENT OPTICS M-Scope type FW
PRODUCT OVERVIEW
Wide Area FFP Measurement Optics M-Scope type FW is the optics for measuring FFP(Far-Field Pattern) with a luminous flux diameter coverage of approx. 3mmφ. The combination of M-Scope type FW, imaging detectors and image processing method enable real-time acquisition and measurement of FFP (Far Field Pattern) of the outgoing beam from the light-emitting device or optical fiber.
By expanding the measurement target flux diameter to approx. 3 mmφ, it has become possible to cope with FFP measurement and emission N.A. measurement such as laser elements with large light emitting area, array type light emitting elements, and large core fibers.
It is possible to easily build an FFP measurement system in combination with SYNOS' Optical Beam Analysis Module AP013. In addition, it is also possible to support optical power distribution analysis such as encircled angular flux analysis, etc.
FEATURE
- Specially designed optics for realtime FFP(Far Field Pattern) observation and analysis
- Wide area design with measurement diameter coverage of about 3mmφ, measurement angle coverage of about ± 43°
- Long working distance design of approx. 4mm
- In combination with SYNOS' Optical Beam Analysis Module AP013, it is possible to easily build FFP measurement and analysis system including optical power distribution analysis function such as EAF (encircled angular flux) analysis, etc.
APPLICATION
- FFP, N.A. measurement of large emission size sample
- Large emission area laser elements, array type laser elements, etc.
- Large core optical fibers
- Various optical modules such as lens modules, etc.
- Encircled angular flux analysis of multi-mode optical fibers, POF and multi-mode devices

SIMPLE STRUCTURE OF WODE AREA FFP MEASUREMENT OPTICS M-Scope type FW
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.
