White Screen Wooden
Product Code : SCL-PLE-11687
The StemAids White Screen (Wooden) is a fundamental optical accessory engineered for the empirical study of image formation, focal points, and light projection. Optimized for Primary and Secondary physics, this screen provides a neutral, high-reflectivity surface required for capturing real images produced by convex lenses and concave mirrors. Manufactured to ISO 9001:2015 standards, its seasoned wooden construction ensures a light-tight, non-reflective backdrop that maximizes contrast for classroom demonstrations on optical benches.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Neutral Matte Interface: Facilitates student visualization of real, inverted images by providing a surface that scatters light evenly without specular highlights, supporting Optics Module 101.
- Focal Point Determination: Enables the physical study of lens equations, allowing learners to apply the screen as a movable target to find the point of sharpest focus.
- Ray Path Verification: Supports the analysis of light behavior, such as shadows (umbra/penumbra) and the magnification of images through various optical media.
- Image Quality Evaluation: Allows students to evaluate the effects of spherical aberration or lens distance on the clarity and brightness of the projected image.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) with anti-scratch protective layers to maintain the integrity of the white matte finish during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and standard English labels.
- Durability: Tropicalized design featuring seasoned wood treated to resist warping in high-humidity laboratory environments.
Direct OEM Sourcing Advantages
Procuring the StemAids White Screen directly ensures vertical manufacturing control:
- In-House Surface Treatment: Screens are batch-tested for color neutrality to ensure they do not introduce chromatic bias to the projected light.
- Batch-Tested for Uniformity: Every unit undergoes a flatness check to ensure the projection plane is perfectly perpendicular to the optical axis.
- Direct Factory Spares Availability: Guaranteed availability of matching wooden bases and standardized screen inserts to maintain a uniform laboratory setup.
- Manufacturing Control: Direct oversight of the wood seasoning process ensures the product remains structurally stable over years of repetitive classroom use.
