Laboratory White Viewing Screen
Product Code : SCL-LAO-12072
Laboratory White Viewing Screen (SKU SCL-LAO-12072) is a 150 x 150 mm matte white steel screen on a 10 mm rod that catches real images, laser lines and interference fringes on an optical bench. It is used in school, college and polytechnic optics practicals. It is produced by Science Lab Supplies, a manufacturer at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, which supplies schools, colleges, tender contractors and distributors without a middleman.
Specifications
Every specification of the 150 mm viewing screen has its own row in the table. In short, a rigid ferrous steel plate carries a non-glare matte white enamel face with a 1 mm metric grid, and a 10 mm stainless steel rod with a thumb-screw collar fixes it in a bench rider or stand.

Applications and Experiments for the White Viewing Screen
On a bench, the screen is moved along the rail until an image or fringe pattern is sharp, and its rider position gives the image distance. The diffusing face keeps patterns visible from across the room, and the printed grid lets students read image height directly.
- Class 12 practical: locating the real image of a Convex Lens 50mm to find focal length by the u–v method.
- Class 12 practical: catching the real image formed by a Concave Mirror (50 mm) and measuring magnification on the grid.
- Class 12 wave optics and B.Sc.: measuring double-slit fringe spacing on a stable plane.
- Laser ray work: a high-contrast target for multi-beam boxes; never reflect beams towards anyone's eyes.
Standard Scope of Supply
Each screen is delivered with its 10 mm stainless steel mounting rod attached, an adjustable thumb-screw locking collar and an instruction manual with optical alignment tips. Bench rails, riders, lenses and light sources are separate items and can be listed on the same quotation when a complete set-up is needed.
Packing, MOQ and Lead Time
Ask for a quotation for one screen or a set for every bench in your optics room. The reply lists packing, delivery time and price for exactly that quantity, and matching benches, lens holders or lenses can be priced alongside it so a whole practical arrives together.

Frequently Asked Questions
Will the screen fit our optical bench?
Yes, if your riders take 10 mm stems. The rod suits benches such as the Optical Bench Ordinary Physics Lab, whose riders accept 10 mm mounting stems, and the collar sets the screen height.
Can we write on the screen with dry-erase markers?
No. The non-glare textured coating is made to diffuse light evenly, not to take markers. Use a separate whiteboard for drawing, and keep the screen face clean with a dry, lint-free cloth.
Is the screen magnetic?
Yes. The plate is ferrous steel, so magnetic indicators, filters or small targets can be fixed to it during set-ups. Hold the assembly by the rod or edges so fingerprints do not stain the white field.
Does Science Lab Supplies make the screen itself?
Yes. The viewing screen is a factory product of Science Lab Supplies in Saha, Ambala, India; the manufacturer prices and dispatches it itself, so there is no agent between your institution and the works.
