Abstract

There is provided an optical characteristic measurement system that can be set up in a relatively short time and can increase a detection sensitivity. The optical characteristic measurement system includes a first measurement apparatus. The first measurement apparatus includes: a first detection element arranged in a housing; a first cooling unit at least partially joined to the first detection element that cools the detection element; and a suppression mechanism that suppresses temperature variations occurring around the detection element in the housing.

Dependent claims

An optical characteristic measurement system comprising:

a first measurement apparatus,
the first measurement apparatus comprising:
a first detection element arranged in a housing;
a first cooling unit at least partially joined to the first detection element, for cooling the first detection element;
a suppression mechanism for suppressing temperature variations occurring around the first detection element in the housing;
and
a first diffraction grating arranged to correspond to the first detection element and configured to guide light in a first wavelength range to the first detection element;
and
a second measurement apparatus,
the second measurement apparatus comprising:
a second detection element arranged in a housing;
and
a second diffraction grating arranged to correspond to the second detection element and configured to guide light in a second wavelength range to the second detection element,
wherein the first detection element of the first measurement apparatus is configured to have a detection sensitivity higher than a detection sensitivity of the second detection element of the second measurement apparatus.
