The CM-3600A offers simultaneous measurement of SCI (specular
component included)/SCE (specular component excluded).
With conventional models, SCI and SCE are switched mechanically by opening and closing an optical trap
provided on the integrating sphere. This conventional method requires mechanical switching whenever SCI
and SCE need to be switched. In addition, it is not possible to start measurement until switching is completed.
The CM-3600A has eliminated mechanical switching and enables acquisition of SCI and SCE
data by performing calculations with the measured data obtained using two light sources.

SCI/SCE SIMULTANEOUS
MEASUREMENT
○
Light sources ① and ② are located as
illustrated at right. Light source ① flashes first.
Memo
・
Light source
①
is a normal diffused
type, and enables the user to obtain SCI
measurement data when it flashes.
○
Next, light source ② flashes.
Memo
・
Light source
②
enables numerical control of
specularly reflected light. The data obtained when
this light source flashes (i.e., the amount of light
on the surface of the specimen) and the one
obtained when light source
①
flashes can then
be used to calculate the SCE measured data.
By performing the above measurement and calculation during each measurement, both SCI and SCE
measurement data can be obtained simultaneously without the need for mechanical switching.
