Convex Mirror
Convex Mirror (Product Code: SCL-392/094) is a round, spherical glass mirror used to study how a diverging mirror forms virtual, diminished images in school and college optics practicals. It has a 50 mm diameter and comes in focal lengths of 15 cm and 25 cm, with optically worked, highly polished glass and ground edges. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is a Convex Mirror Used For?
A convex mirror spreads reflected light outwards, so it always forms a virtual, erect and diminished image — the same principle as a vehicle’s rear-view mirror. In the lab, students compare its images with those of plane and concave mirrors and, in senior classes, find its focal length with the help of a convex lens on an optical bench.
Having two focal lengths lets teachers match the mirror to the lens and bench length available, which keeps it a flexible item of physics lab equipment in India. Hold the mirror only by its ground edges, keep the polished face free of fingerprints, and store each mirror separately in a padded box.
What to Specify When Ordering
- The focal length you need: 15 cm or 25 cm.
- How many mirrors of each focal length are required.
- The mounting or holder needed to use the mirror on your optical bench.
OEM Manufacturer
The Convex Mirror comes from Jain Scientific Equipments Private Limited, which trades as ScienceLab and manufactures its school optics range as the OEM at its own factory in Saha, Ambala, Haryana, India. Ordering from the maker lets schools, dealers and importers combine both focal lengths in one quotation and return to the same source for repeat quantities. More about the company is on its profile page.

Frequently Asked Questions
What focal lengths are available for the Convex Mirror?
The Convex Mirror is available with focal lengths of 15 cm and 25 cm, both on a 50 mm diameter mirror. State which focal length you need, or how many of each, when you request a quotation so the order matches your practical method.
What size is the Convex Mirror?
The Convex Mirror is round with a diameter of 50 mm. It is made of spherical, optically worked glass with ground edges and a highly polished surface, giving a clear reflected image for student optics experiments.
What kind of image does the Convex Mirror form?
The Convex Mirror always forms a virtual, erect and diminished image, whatever the object distance. Because that image cannot be caught on a screen, the mirror’s focal length is usually found with the help of a convex lens on an optical bench.
How is the focal length of the Convex Mirror measured?
First form a real image with a convex lens, then place the Convex Mirror between the lens and that image and move it until the image retraces its own path. The distance from the mirror to the image position is then its radius of curvature, twice the focal length.
How should the Convex Mirror be cleaned and stored?
Clean the Convex Mirror with a soft lens tissue or cloth, holding it only by its ground edges, and store it in a padded box away from other glassware. Although it is listed as chemical and heat resistant, the polished surface should be kept free of scratches.
Who manufactures the Convex Mirror?
The Convex Mirror is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own factory in Saha, Ambala, Haryana, India. It is supplied factory-direct to schools, colleges, dealers and importers in India and international markets.
