Fluorescence is a phenomenon in which a molecule absorbs light with a short wavelength of high energy and emits light with a wavelength longer than that. When a molecule absorbs light, it moves up to a higher energy excited state. When a molecule that absorbs light ascends to an excited state, it becomes unstable and emits energy in the form of heat or emits light of a different wavelength and falls into its original state.

A fluorescence spectrophotometer, known as a fluorescence spectrometer, measures the fluorescence emitted from a material to determine how much fluorescence is emitted at which wavelength.

Specifically, a fluorescence spectrophotometer excites light generated in a lamp by excitation at an excitation monochromator and irradiates the sample. The light emitted from the sample is passed through an emission monochromator and then detected by a fluorescence detector Analysis.

However, in the conventional optical analysis apparatus, only the fluorescence analysis can be performed in the case of the fluorescence analysis apparatus, and the UV-Vis absorption spectroscopic analysis can not be performed.

The lamp 130 serves to excite the sample to excite the specimen in order to measure a specific fluorescence emission signal. Therefore, the lamp should emit a beam of radiation of sufficient intensity to cause fluorescence, and the intensity of the output should be stable for a certain period of time. Ideally, the lamp 130, which is a light source, emits the same photon intensity for all wavelengths to be measured, but it is merely an ideal light source and has a specific photon intensity for the intrinsic wavelength depending on the type of light source.

The lamp 130 may be, for example, a high pressure xenon lamp, a pulsed xenon lamp, a Xe-Hg arc lamp, a quartz-tungsten halogen lamp, an LED light source, a laser diode,

In this case, the cuvette holder 122 shown in FIGS. 1 to 3 is set to guide the light emitted from the sample only to the light absorbing module 123. Therefore, the light emitted from the sample in the cuvette holder 122 does not guide light toward the emitting monochromator 140.

Hereinafter, the specific structure of the cuvette holder will be described. The principle of selectively guiding the light emitted from the sample to the cuvette holder by the light absorption module 123 and the emission monochromator 140 will be described.

Therefore, the cuvette 122c can be inserted into the cuvette insertion hole 127 formed in the upper surface of the main body 122d. The basic shape of the main body 122d is not limited to a hexahedron (or a hexagonal column), but may be a cylindrical shape or the like.

The incident window 122e, the first exit window 122f and the second exit window 122g correspond to the side surface of the cuvette 122c when the cuvette 122c is mounted on the cuvette insertion hole 127 Respectively.

The cuvette holder 122 includes a first insertion channel 122ac into which a first screen door 122a for opening and closing the first emission window 122f is inserted and slid, And a second insertion channel 122bc into which a second screen door 122b for opening and closing the second screen door 122b is inserted and slid.

The second screen door 122b is slidably inserted into the second insertion channel 122bc and has a second screen part 122bb for blocking the second output window 122g and a second screen part 122bb And a second handle 122ba bent in a direction away from the main body 122d at an exposed upper end of the second handle 122b.

The first screen door 122a and the second screen door 122b are operated by the operator to apply upward force to the first handle 122ab and the second handle 122bb formed on the upper side to open the exit window, And closes the exit window.

2, the cuvette holder 122 is in a state of being placed in an absorption mode (i.e., a state of irradiating light to the light absorption module) The second screen door 122b is lifted upward to open the window 122g and the first emission window 122f in the direction (-X direction) arranged toward the emission monochromator 140 is set to be closed have.

FIG. 3 shows a path through which the light travels by the cuvette holder 122, which is set to control light in the direction of the light absorption module.

2 and 3, the second screen door 122b is raised upward to open the second exit window 122g, and the first screen door 12a descends downward, 1 emission window 122f is closed.

Accordingly, the excited light introduced into the incident window 122e is irradiated to the cuvette 122c, and the light emitted from the sample contained in the cuvette 122c can not proceed to the closed first exit window 122f, And proceeds through the second exit window 122g, which is an open window, to proceed to the light absorbing module 123 placed on the subsequent light path.

Alternatively, the first screen door may be fixed by a separate complementary fastening structure so that it does not fall due to its own weight when it is disposed on the upper side in the first screen door insertion channel.

Similar fitting or complementary fastening structures may be applied between the second screen door 122b and the second screen door insertion channel 122bc.

FIG. 4 is a perspective view of a fluorescence mode of an optical analysis apparatus according to an embodiment of the present invention, and FIG. 5 is a partially enlarged view showing a state of a screen door of a cuvette holder in the fluorescence mode of FIG.

4 and 5 are different from those of FIGS. 1 to 3 in the setting of the screen door of the cuvette holder, and accordingly, the path of the light emitted from the cuvette holder 122 is different.

4 and 5, the light generated by the lamp 130 is extracted into the specific monochromatic light excited by the excitation monochromator 110. FIG.

The light irradiated from the excitation monochromator 110 is bent along the light propagation path intended by the first reflector 152 and the second reflector 154, for example.

The light reflected by the second reflecting part 154 passes through the beam splitter 151 and passes through the light passing housing 125 provided on the vertical wall of the light path control part 120 to be passed through the light path control part 120, And enters the inside.

Light entering the light path control unit 120 goes straight and reaches the cuvette holder 122.

4 and 5 show a case in which the cuvette holder 122 according to the embodiment of the present invention is adapted to perform the fluorescence mode. 4 and 5, the light emitted from the sample by the excited light irradiated on the cuvette holder 122 is emitted in a direction (-X direction) perpendicular to the path of the excited light And the light is guided to the monochromator 140.

In FIGS. 4 and 5, the progress path of light controlled in the cuvette holder 122 is indicated by an arrow. At this time, the cuvette holder 122 is set such that the light emitted from the sample is guided to the emission monochromator 140 only.

Therefore, the light emitted from the sample in the cuvette holder 122 does not guide light toward the light absorbing module 123.

FIG. 5 is an enlarged view of a specific configuration of the cuvette holder 122 shown in FIG. 4. Specifically, FIG. 5 shows a state of the cuvette holder set to guide light to the emitting monochromator 140.

5, since the cuvette holder 122 is in a state of being in a fluorescent mode (i.e., a state in which light is emitted by the emission monochromator), the direction in which the emission monochromator 140 is disposed The first screen door 122a is lifted upward to open the first emission window 122f of the light absorbing module 123 and the second emission window 122g in the direction (Y direction) So that the second screen door 122b descends downward.

Therefore, the excited light introduced into the incident window 122e is not irradiated onto the cuvette 122c and the light emitted from the sample contained in the cuvette 122c can not proceed to the second exit window 122g, which is closed. Instead, And proceeds through the first exit window 122f, which is an open window, so that the light proceeds only to the emission monochromator 140 placed on the subsequent optical path.
