Product Code : EL-SLE-4757
Jlab Export is a leading Convex Mirror (Vacuum Type) Manufacturer,and suppliers in India
Convex Mirror (Vacuum Type) (code EL-SLE-4757) is a spherical convex mirror made from optically worked glass, silver coated at the back and finished with smooth edges, used for reflection and image-formation experiments in school and college optics labs. It is offered in focal lengths listed as F/L 5, 10, 15, 20, 25 and 30, and the vacuum type is listed for its longer life. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Convex Mirrors?
| Model | Construction (as listed) | Focal lengths | Other listed details |
|---|---|---|---|
| This vacuum-type mirror (EL-SLE-4757) | Optically worked glass, silver coated at the back | F/L 5 to F/L 30 | Smooth edges; listed for superior long life |
| Convex Mirror | Optically worked glass, silver coating at the back | F/L 5 to F/L 30 | No long-life or edge finish details given |
| Convex Mirrors (cylindrical) | Stainless steel, cylindrical | Not stated | For cylindrical-mirror demonstrations rather than spherical-mirror practicals |
Choose the vacuum type when mirrors are handled by many classes over several years and you want the version listed for longer life with finished edges. The plain convex mirror covers the same focal lengths, and the stainless-steel cylindrical mirror is a different shape for curved-mirror demonstrations.
What Is a Convex Mirror Used For?
A convex mirror bulges towards the viewer and spreads reflected light out, so it always forms a virtual, upright and smaller image and shows a wide field of view — the reason convex mirrors are used as vehicle rear-view and shop security mirrors. In the class 10 chapter on reflection and refraction of light, students use one beside a concave mirror to compare the images the two form, and in class 12 physics practicals they find the focal length of a convex mirror with the help of a convex lens on an optical bench. College optics labs use the same mirrors for ray-diagram verification.
Hold the mirror by its edge, clean the front glass only with lens tissue, protect the silvered back from scratches, and store each mirror in a padded box so the coating lasts.
What to Specify When Ordering
- Focal length — F/L 5, 10, 15, 20, 25 or 30, and the unit you expect, with the number of mirrors in each.
- Quantity — the minimum order is 10 units; schools commonly buy a set of focal lengths for each optics bench.
- Holders and bench — add a lens or mirror holder and an optical bench to the same enquiry if you need complete set-ups.
Frequently Asked Questions
Which focal lengths can I order?
The listing gives F/L 5, F/L 10, F/L 15, F/L 20, F/L 25 and F/L 30. It does not state the unit, so give the focal length and unit you need in your enquiry and JLab will confirm.
How is the vacuum type different from the plain convex mirror?
Both are made from optically worked glass with a silver coating at the back and cover the same focal lengths. The vacuum type is listed for superior long life and with smooth finished edges; the plain listing does not mention these points.
What kind of image does a convex mirror form?
Always a virtual, upright and diminished image, whatever the object distance. That is why it gives a wide view and cannot throw an image onto a screen on its own.
How do students find the focal length of a convex mirror?
Usually with a convex lens on an optical bench: the lens converges light towards a point behind the mirror, and when the mirror sits where the light retraces its path onto the object pin, its distance from that point equals the mirror’s radius of curvature; the focal length is half of that.
Is a holder or stand included?
No, this listing covers the mirror only. A wooden lens holder and an optical bench are separate items, linked below.
Who manufactures this convex mirror?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India, and quotes for it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of optics and physics lab equipment in India, incorporated in 2017 and working from Hargolal Road, Ambala, Haryana. These mirrors leave JLab’s own works directly rather than passing through a trader, so schools, colleges, dealers and importers buy them factory-direct; each one is visually inspected before it is packed, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Jamaica in Central America and the Caribbean, Greece in Southern Europe, Mexico in North America, Botswana in Southern Africa and Oman in the Middle East. For tenders, see the JLab lab tenders page.
Mirrors, Lenses and Optics Bench Items
- Convex Lens — the converging lens used alongside a convex mirror to find its focal length.
- Concave Mirror (Vacuum Type) — the concave counterpart in the same focal lengths, for comparing images.
- Wooden Lens Holder — a wooden upright with a V-slot that holds a lens or mirror on the bench.
- Optical Bench Wooden — keeps mirrors, lenses and screens in line for optics experiments.
More optics lab equipment for schools is listed in the School Lab Equipment range.
