Lenses Cylindrical Glass, Planoconvex
Lenses Cylindrical Glass, Planoconvex (Product Code: SLE/PHY/110) is a converging cylindrical glass lens with one flat and one curved face, used to focus light and study refraction in physics optics practicals. Students and teachers use it to compare lens shapes and the effect of lens orientation, and it has a listed focal length of 75 mm. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for school optics experiments.

What Is the Planoconvex Cylindrical Lens Used For?
The flat back face makes this lens ideal for showing that orientation matters. Send parallel rays onto the curved face first and they converge to a fairly sharp line focus; turn the lens round so the flat face meets the light and the rays cross over a longer, more spread-out region. Students can record both ray patterns on paper and discuss why optical designers usually point the curved side towards parallel light.
The flat face also sits neatly against a glass block or plane mirror, so the lens can be combined with other components in ray-box experiments. Used with the biconvex and biconcave lenses of the same series, it rounds out a convex and concave lens set for school optics. Handle it by the edges and store it in its pouch and case.
What to Specify When Ordering
- Lens shape — planoconvex, biconvex or biconcave.
- Number of lenses required for each student group.
- Whether the whole three-lens series should be quoted together.
OEM Manufacturer
The planoconvex lens is produced by ScienceLab, which is the trading name of Jain Scientific Equipments Private Limited, at its licensed factory in Saha, Ambala, Haryana, India. The company is a registered MSME enterprise with manufacturing as its major activity (Udyam UDYAM-HR-01-0003714), and its export shipments are handled under Importer-Exporter Code AAECJ8618A (DGFT). As the OEM, it sells direct to schools, colleges, dealers and importers; see our company profile for more.

Frequently Asked Questions
What is the focal length of the Lenses Cylindrical Glass, Planoconvex?
The Lenses Cylindrical Glass, Planoconvex has a listed focal length of 75 mm, the same figure given for the biconvex and biconcave lenses in the series. That makes side-by-side comparisons of lens shape straightforward in one practical session.
Which way round should the planoconvex lens face the light?
For the sharpest focus, turn the curved face of the Lenses Cylindrical Glass, Planoconvex towards incoming parallel rays and the flat face towards the focus. Reversing it spreads the crossing points over a longer distance, which is itself a good experiment on aberration.
How is the lens supplied?
The Lenses Cylindrical Glass, Planoconvex comes as a single precision-finished lens, individually pouched and supplied in a neat presentation case. Teachers can issue each lens in its pouch and collect it back after the lesson to keep the faces clean.
What are the lens dimensions?
The Lenses Cylindrical Glass, Planoconvex is listed at 50 x 45, but the original description does not state the unit. Please confirm the dimensions through our contact page if the lens must fit a particular ray box, holder or storage tray.
Who manufactures the planoconvex lens?
The Lenses Cylindrical Glass, Planoconvex is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), acting as OEM, at its own factory at Saha, Ambala, Haryana, India. The manufacturer quotes and supplies it directly to institutions, dealers and importers.
Do you supply export orders?
Yes. The Lenses Cylindrical Glass, Planoconvex can be supplied to schools, colleges and dealers across India and international markets. Share the quantity, any other lenses you need from the series and the destination through the contact page for a quotation.
