HIGH POWER LASER BEAM PROFILER / NFP&FFP MEASUREMENT & ANALYSIS OF HIGH POWER BLUE LASER
M-Scope type HD/BL

NFP/FFP SIMULTANEOUS MEASUREMENT OPTICS FOR BLUE HIGH POWER LASERNFP/FFP simultaneous measurement optics, customized especially for output ~10W class high power blue laser.

M-Scope type HD is the optics for simultaneous measurement of NFP and FFP for output
1~10W class high power blue lasers by single optical unit. After passing through the objectivelens, the luminous ﬂux emitted from the sample is 99.99% attenuated by two-stage beam
sampler unit, and imaged on the detector. The optical system is equipped with an NFP
measurement port and an FFP measurement port. Luminous ﬂux incident on the optical system
is branched to each measurement port. In this way, NFP measurement and FFP measurement
can be performed simultaneously with a single optical system.
【Features】○Simultaneous NFP and FFP measurement of high power blue laser by single optical unit
○Attenuation of incident beam with two-stage beam sampler and ND ﬁlters○In combination with a coaxial epi-illumination, alignment by microscopic image is possible.
○High-performance NFP measurement system can be constructed by using Synosʼ optical beam
analysis module AP013 together.
【Optics selection】* Please contact us regarding the measurement wavelength.

The light ﬂux emitted from the sample is attenuated to approximately 99.99% by two beam samplers installed in the latter stage of 1stobjective lens. The beam reﬂected by the beam sampler is absorbed by the beam damper installed in the optical system. The light ﬂux that has
passed through the beam sampler forms an aerial image through the imaging lens. After that, the light ﬂux is split by the half mirror after thesecond objective lens, the transmitted light ﬂux is relayed to the NFP detector, and the reﬂected light ﬂux is relayed to the FFP detector. The
image formed on the image detector for NFP/FFP is subjected to each NFP/FFP analysis by image processing analysis. An aperture can beinserted in the aerial image part in the middle of the optical path.
