Structure and components This optical instrument is composed of light pipes, light pipe rack components, light intensity regulators, potentiometer knobs, light pipe rack legs, light source switches, power sockets, light source wiring, white screens, and white screen racks. Light pipe design and function 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 inside the condenser lens barrel, and the condenser lens barrel can expand and contract within the objective lens barrel. This enables adjustment of the size and definition of the beam spot that is projected onto the white screen. Installation Attach the support feet to the light pipe rack and to the white screen. Insert the light pipe into the round hole of the light pipe holder and rotate to align. Place the white screen approximately 140 mm away from the beam exit end of the light pipe. Operation and adjustment Turn on power and illuminate the lightemitting diode. Adjust the position of the diode holder and the condenser lens tube so that the edge of the spot on the white screen is clear. Each of the three light pipes can be adjusted independently to achieve the desired beam spot quality. Key benefits Independent control: three light pipes can be adjusted separately for precise multichannel beam experiments. Adjustable beam size and definition: expansion and contraction of the condenser lens tube inside the objective lens tube allow fine tuning of spot size and sharpness on the white screen. Easy setup: straightforward installation with stable feet and simple alignment via roundhole light pipe holder. Visual feedback: white screen provides clear visualization of beam position, edge sharpness, and spot quality for optical alignment tasks. Practical power and control: builtin light intensity regulators, potentiometer knobs, light source switches, and power sockets support stable, adjustable illumination. Specifications and attributes to note Main components include light pipes, light pipe rack components, light intensity regulators, potentiometer knobs, light pipe rack legs, light source switches, power sockets, light source wiring, white screens, and white screen racks. Light pipe assembly: diode holder, condenser lens tube, and objective lens tube with adjustable rotation and translation for spot optimization. Screen distance: white screen positioned about 140 mm from the beam exit end of the light pipe. Independent adjustment: three light pipes can be tuned separately to achieve distinct beam characteristics. Recommended use scenarios Educational beam visualization: in physics classrooms or teaching labs, demonstrate light paths, beam alignment, and spot formation with three independently adjustable channels. Optical alignment and calibration: in research or manufacturing settings, use the instrument to align components and verify beam spot size and sharpness on screen. Multichannel beam experiments: compare and analyze three separate beams or test configurations simultaneously, adjusting each channel to meet experimental requirements.
