Can be expressed according to the storage interval.

In addition, the sample or the light detecting unit 500 may be disposed on the sample placing unit 400, and the position and the amount of light of the plurality of lamp members may be sensed. The detected data may be converted into a detection signal S500 and transmitted to the feedback control step S650. In the feedback control step S650, the sensing signal S500 may be received and the light source position setting unit 620 or the power setting unit 630 may be controlled to reach the set target value.

The feedback control step (S650) controls the light source position setting step (S620) and the power setting step (S630), so that the light detecting unit 500 detects the position or the light amount of the lamp member in the process of reaching the previously input target value. And by transmitting the detection signal (S500) to the graphic representation step (S640), the experimental result value can be represented in the graphic representation step (S640), the user can monitor.

As illustrated in FIG. 8, the graphic unit 640 may display a target value, a range of an upper limit and a lower limit during the test, and may express the amount of light of the current light source unit 200.

When the detection signal S500 and the target values of the light source position setting step S620 and the power setting step S630 coincide with each other, the experimental data may be stored in the data storage unit 600. When the detection signal S500 is within an allowable error range of the target value by user manipulation, the experimental data may be stored.

According to another embodiment of the present invention, by selecting any one of the stored height in the height setting step (S610) stored in the data import step (S660), and selects the target amount of light of the previously stored light source unit 200, The power setting step S630 and the light source position setting step S620 may be controlled to output an amount of light.

As shown in FIG. 9, a plurality of lamp members, a first driving member 310, and a second driving member 430 of the light source unit 200 may further include a driving detection sensor that senses driving. In addition, the control device CD may further include a sensor monitor, and transmits a drive detection signal transmitted from the drive detection sensor to the remote control device RC, and transmits a plurality of light sources 200 to the remote control device RC. The lamp member, the first driving member 310, and the second driving member 430 may be displayed. In this case, the sensor monitor may individually turn on and off the plurality of lamp members of the light source unit 200, and may control the first driving member 310 or the second driving member 430 to be driven or not driven. .
