Its pretty inexpensively (aka cheaply) made, but there are no undue stresses, so it should last a long time. Review: It help to improve teaching - It was as expected ## Features - Optics Elements for Interference Diffraction Optical Physical Experiment. - Suitable for who are prepared for physics by understanding the interference and diffraction of light in advance. - This kit is used in class to illustrate the phenomenon of light interference. - This film is made of PET material, please do not use high power laser to avoid damage to the film. - Properly increasing the distance between the observation plate and the film can make the diffraction phenomenon more obvious. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CJDX8Y9P | | Battery Description | Alkaline | | Best Sellers Rank | #100,342 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #31 in Science Classroom Optics Kits | | Brand Name | Laserlands | | Customer Reviews | 4.7 out of 5 stars 18 Reviews | | Educational Objective | Observation Skills, Exploratory Skills, STEM, Concept Development Skills | | Included Components | Single Slit×1 Double Slits×1,Holder×2,Observation Board×1,Red Light Source×1 | | Item Dimensions | 7.09 x 3.74 x 3.15 inches | | Item Weight | 13.12 ounces | | Manufacturer | Laserland | | Manufacturer Maximum Age (MONTHS) | 144 | | Manufacturer Part Number | B Plus | | Model Number | B Plus | | Number of Items | 1 | | Number of Packs | 2 | | Size | 3.74 x 7.09 x 3.15 inches | | UPC | 712201504545 | | Unit Count | 1 Count | ## Images ![Young's Double-Slit Experiment, Single Slit, with Holder Observation Board Red Light Source, Optics Elements, Optical Physical Experiment Kit, Interference Diffraction Grating Sheet 50 * 50mm - Image 1](https://m.media-amazon.com/images/I/41bHkk3xA7L.jpg) ![Young's Double-Slit Experiment, Single Slit, with Holder Observation Board Red Light Source, Optics Elements, Optical Physical Experiment Kit, Interference Diffraction Grating Sheet 50 * 50mm - Image 2](https://m.media-amazon.com/images/I/51P4VQMLzmL.jpg) ![Young's Double-Slit Experiment, Single Slit, with Holder Observation Board Red Light Source, Optics Elements, Optical Physical Experiment Kit, Interference Diffraction Grating Sheet 50 * 50mm - Image 3](https://m.media-amazon.com/images/I/51WjVQXhWiL.jpg) ![Young's Double-Slit Experiment, Single Slit, with Holder Observation Board Red Light Source, Optics Elements, Optical Physical Experiment Kit, Interference Diffraction Grating Sheet 50 * 50mm - Image 4](https://m.media-amazon.com/images/I/41WwbXM3KyL.jpg) ![Young's Double-Slit Experiment, Single Slit, with Holder Observation Board Red Light Source, Optics Elements, Optical Physical Experiment Kit, Interference Diffraction Grating Sheet 50 * 50mm - Image 5](https://m.media-amazon.com/images/I/514guOQukkL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fairly basic but gives good results. *by R***E on July 31, 2026* This is a low-cost way to very easily demonstrate the findings of the double-slit experiment.
