YZHYYDS 3-Color Light Source Demonstrator, Light's Three Primary Color Synthesis Experiment Device With Projection Screen,Light Source Direction & Intensity Adjustable, for Physics Teaching

YZHYYDS

【Light Tricolor Science Apparatus】This machine allows you to explore the fascinating world of color mixing. Whether you are a student, or science lovers and technology, this compact apparatus is guaranteed to provide hours of educational and entertaining fun. 【Direction & Intensity Adjustable】The adjustable beam angles allow the three colored images to overlap and create a stunning array of mixed colors. With the potentiometer adjustment, you can control the intensity of each LED separately to create various shades of mixed colors. 【Light Pipe】The light pipe is formed by the sleeve connection of the diode holder, the condenser lens tube and the objective lens tube. The diode holder can rotate and expand in the condenser lens barrel, and the condenser lens barrel can expand and contract inside the objective lens barrel to adjust the size and definition of the spot of the outgoing beam on the white screen. 【Complete Teaching Kit with Screen】Comes equipped with a dedicated projection screen to enhance visibility in classroom or laboratory settings. The high-contrast display ensures that color mixing results are sharp and clear, facilitating group demonstrations and student observation. 【Install the Instrument】Install the support feet on the light pipe rack and the white screen respectively. The light pipe is inserted in the round hole of the light pipe holder to rotate the ball. The white screen is placed about 140mm away from the end of the light pipe (beam exit end).
