Concave Mirror Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4763
Jlab Export is a leading Concave Mirror Manufacturer,and suppliers in India
Concave Mirror (code EL-SLE-4763) is a 50 mm diameter mirror with optically true surfaces, used in physics labs to show how a curved mirror collects light, focuses it and forms images. A silver coating at the rear is sealed with a layer of epoxy paint, and the mirror is offered in focal lengths F/L 5, 10, 15, 20, 25 and 30 for school and college practicals. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is This Concave Mirror Used For?
Moving an object towards a concave mirror shows the whole range of mirror images in one practical: far away, the image is a small, inverted, real point near the focus; at the centre of curvature it is real, inverted and the same size; between the centre and the focus it is real and enlarged; and inside the focus it becomes virtual, upright and magnified. Students record these positions with a candle or an illuminated object and a screen — the image-formation work of the class 10 light chapter — and in class 12 they measure the focal length more precisely by the u–v method on an optical bench. The same light-collecting property explains torch reflectors and solar concentrators, which makes the mirror useful for demonstrations as well as measurement. Keep the reflecting face free of fingerprints and store the mirror so the epoxy-sealed back is not scratched.
What to Specify When Ordering
- Focal length and unit — F/L 5, 10, 15, 20, 25 or 30, with the number of each.
- Quantity — the minimum order is 10 units.
- Version and mounts — this mirror or the vacuum-type concave mirror, plus holders or an optical bench if required.
Frequently Asked Questions
What is the diameter of this concave mirror?
50 mm. It is listed in focal lengths F/L 5, 10, 15, 20, 25 and 30; the unit for the focal length is not given, so state the one you need in your enquiry.
Where is the image when the object is at the centre of curvature?
At the centre of curvature too: real, inverted and the same size as the object. This is a quick way for students to check the radius of curvature, which is twice the focal length.
Is this the same as the vacuum-type concave mirror?
Both are 50 mm concave mirrors in the same focal lengths with a silver and epoxy back. The vacuum-type listing is described as having a superior longer life; this standard listing does not make that claim.
Who manufactures this concave mirror?
JLab — Jain Laboratory Instruments Pvt Ltd — makes it at its works in Ambala, Haryana, India, and quotes for it directly as the manufacturer.
OEM Manufacturer
Jain Laboratory Instruments Pvt Ltd, known as JLab (company profile), is a school and college science equipment manufacturer in India, incorporated in 2017 with its works on Hargolal Road, Ambala, Haryana. These mirrors are produced in-house rather than bought from a trading firm, so schools, colleges, dealers and importers buy factory-direct, each mirror is visually inspected before it ships, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — Tanzania in East Africa, Tonga in Oceania, the Dominican Republic in Central America and the Caribbean, Sri Lanka in South Asia and Sierra Leone in West Africa are a few examples. Tender buyers can see the JLab lab tenders page.
Other Mirrors and Optics Mounts
- Concave Mirror (Vacuum Type) — the 50 mm vacuum-type version, listed for longer life.
- Convex Mirror — a diverging mirror for comparing virtual images.
- Plane Mirror — for laws-of-reflection experiments.
- Wooden Lens Holder — holds a lens or mirror upright.
- Optical Bench Wooden — for u–v measurements with mirror, object and screen in line.
