Product Information:_..

This precision interferometer for optics experiments combines premium optical components with a solid, heavy-duty base plate to deliver precise, reliable, and repeatable measurement results.
The large optical components generate bright, well-defined interference patterns, making observation possible even in daylight.
An adjustable reflective observation screen improves alignment and visibility, while pre-positioned component locations allow rapid rearrangement and quick setup for different experiments. This makes the interferometer ideal for physics education, laboratory demonstrations, and advanced optical measurements.
Supplied with a sturdy plastic case, the kit ensures secure storage and reliable protection for the interferometer and laser base plate.
