OPTICS AND OPTICAL MEASUREMENT INSTRUMENTS
NFP/FFP SIMULTANEOUS MEASUREMENT OPTICS M-Scope type D
PRODUCT OVERVIEW
M-Scope type D realizes simultaneous observation and analysis of NFP and FFP by a single optical unit.
Previously, for measurement and analysis of NFP and FFP, dedicated two kinds of optics, NFP measurement optics and FFP measurement optics, are needed. M-Scope type D realized simultaneous observation and analysis of NFP and FFP without changing optics by using specially designed single optical unit.
By selecting imaging detector, it will be applicable for optical beam profile observation and analysis from 400~1700nm wavelength range.
It is also possible to construct the NFP/FFP simultaneous measurement system by combining with various imaging detectors and Synos' Optical Beam Analysis Module AP013.

SIMPLE STRUCTURE OF NFP/FFP SIMULTANEOUS MEASUREMENT OPTICS M-Scope type D
In M-Scope type D, FFP is measured using objective lens. In the figure on the left, the luminous flux emitted from the emitting point is incident on the objective lens and then the optical path is split by the half mirror. The light flux that has passed through the half mirror advances to the NFP port side and is imaged on the NFP measurement detector via the focusing lens. On the other hand, the light flux reflected by the half mirror advances to the FFP port side and is imaged on the FFP measurement detector via the FFP relay lens. In this way, NFP and FFP images obtained from each port branched into two optical paths are analyzed by image processing, and NFP/FFP measurement are realized with a single optical unit.
Since this optics uses objective lens to measure NFP/FFP, the diameter of the light flux to be measured is very narrow (about 100 μm), it is necessary to adjust the position and focus on the NFP image. Additionally, the measurement wavelength is limited because appropriate AR coating is required for optical path splitting half mirror of NFP/FFP port. These are major differences from the FFP measurement method using f-θ lens.
