While 0.3mm slit gave correct results with an average error 1.7%, 0.2mm slit gave consistently wrong results. Although it would be difficult to confirm, I suspect the slit is labelled wrongly on a diaphragm and is actually 0.25mm wide. Then average error would be then 1.89%, not 18.5%, consistent with other measurments. With both slits I did 9 measurments, distances from 1m to 5m using 635nm laser provided in the set. ## Frequently Bought Together - 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 - Diaphragm with 4 Double Slits of Different Spacings - Polarized Film Sheets 3 PCS 7.8 x11.8inches/20x30cm Polarizer Linear Polarizing Filter Non-Adhesive for Educational Physics Photography Lighting --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/602969846-laserland-single-slit-double-slits-combination-trellis-design-optics-elements](https://www.desertcart.ph/products/602969846-laserland-single-slit-double-slits-combination-trellis-design-optics-elements) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-18*
