Focused light projection: Power on the LED to illuminate the beam. Adjust the diode holder and condenser lens tube position to produce a clear light spot on a white screen. Flexible beam control: Rotatable diode holder and expandable condenser lens barrel let you tailor beam size and clarity on the white screen for different tasks. Simple setup: Attach the support feet to the light pipe rack and the white screen. Insert the light pipe into the holder and position the white screen 140 mm from the beam exit for accurate projection. Comprehensive equipment: Includes light pipes, rack components, intensity regulators, knobs, legs, switches, sockets, wiring, screens, racks, and related accessories for a complete system. Use case: Educational demonstrations and optical experiments Demonstrate basic light paths, beam size adjustment, and spot projection in classrooms or laboratories. Suitable for teaching principles of illumination, alignment, and measurement with a visible, controllable light spot. Use case: Manufacturing alignment and inspection Provide a controllable light spot to aid alignment of fixtures, surfaces, or features. Adjustable beam size and clarity support simple inspection and verification tasks. Use case: Calibration and presentation setups Calibrate sensors or test benches that require a stable, repeatable light spot on a white screen. Clear visibility and adjustable projection improve accuracy in demonstrations and technical talks.
