       Young’s double-slit interference experiment is a classic optical experiment in the College Optical-Physics Experiments. In 1801, Thomas Young (1773-1829) conducted an interference experiment of light, known as Young's two-hole interference experiment, and confirmed the wave character of light for the first time. Later, he established a new wave theory based on the interference principle, explained Newton’ in his papers s ring, and accurately measured the wavelength in his papers. In Young’s double-slit experiment, since there is a small slit s, light waves arriving at s become two secondary wave sources that transmits cylindrical waves. And they transmit one secondary cylindrical wave, respectively. The two secondary waves have the same frequency, since they come from the same wave surface. The vibration directions of s1 and s2 are approximate due to the close distance between them. Since the vibration phase differences of s1 and s2 remain constant, the two light waves meet the coherent condition, thus forming interference fringes on the screen. This is a typical optical experiment that obtains coherent optical waves using the wavefront splitting method.

       Through building the Young’s double-slit interference cage system, students solve various problems encountered during experiments to develop a further understanding of the theoretical knowledge and the principle of optics about the system. OMTOOLS offers the Young’s double-slit interference cage system kit for teaching or research use in a variety of optical laboratories. An OD 25.4 mm optic fiber collimator with FC/PC interfaces is included in the kit, and we also provide optional light sources. The system is compatible with your light sources and OD 25.4 mm optic fiber collimators. For optic fiber collimators with other outer dimensions such as 9 mm, 11 mm, 12 mm, 16 mm, and 18 mm, or other customized dimensions, we provide collimator adapters with SM1 threads. To facilitate the compatibility with adapters, we can replace the OMTF25A lens mounts with jack screws and fixed light sources with the OMTF25B lens mount with clamping rings free of charge. (Note: this kit only includes one optical double slit. See the slit specifications below if other slits are required)
