Quick answer: STEMAids manufactures and supplies 25 light and optics products across six groups: individual lenses and optical elements from ₹15, optical benches and mounting systems from ₹70, refraction glass slabs and prisms from ₹35, laser and ray-optics kits from ₹390, interference and diffraction apparatus from ₹190, and demonstration kits from ₹115 — all listed on stemaids.com on 28 August 2026. Eduscope Smart Learning Solutions Private Limited is Udyam-registered for laboratory equipment manufacturing (UDYAM-DL-06-0069460) and ISO 9001:2015 certified, supplying schools, colleges and vocational institutes across India and for export.
STEMAids supplies optical-bench and light apparatus as part of its Physics Lab Equipment Supplier range, complementing its laboratory microscope manufacturer catalogue, for schools across Delhi and pan-India.
Ray optics is taught almost entirely through apparatus, not diagrams: a student who has never actually traced a ray through a glass slab or split white light with a prism will struggle to reason about refraction and dispersion on an exam, however clearly the textbook figure is drawn. Light & Optics covers the physical instruments that make that possible, from a single ₹17 convex lens up to a ₹5,990 optical spectrometer for senior-secondary spectral analysis. Optical bench rail length and lens mount compatibility matter here in a way they don’t for most other physics apparatus, since a lens, lamp house and screen bought from different sources may simply not fit the same rail.

Buyers upgrading from an entry-level setup should note the difference between the Optical Bench Ordinary and the Single Rod Optical Bench: the ordinary bench uses a wider rail with separate uprights, while the single-rod design keeps all components on one axis, which most schools find faster to align during a 40-minute practical period.
Applying the 6-S Framework to Light & Optics
Syllabus: lens and mirror practicals belong to secondary-level ray optics, while double-slit and spectrometer apparatus belong to senior-secondary and undergraduate wave optics — match the apparatus tier to the syllabus level, not just the topic name. Specification: confirm optical bench rail length and lens-holder compatibility before ordering lamp houses or screens separately, since mismatched rail systems are the most common return reason in this category. Safety: laser ray boxes should be low-power classroom-safe units; confirm laser class rating before classroom use with younger students. Sturdiness: glass slabs and prisms should be edge-polished to avoid chipping during repeated student handling. Spares: lenses, screens and alignment pins are the most frequently reordered items in this category. Supporting documents: manufacturer specification sheets and the statutory document pack are available via the Tenders page for institutional and government procurement.
Frequently Asked Questions
What is included in the Light & Optics category?
Twenty-five products across six groups: individual lenses and optical elements, optical benches and mounting systems, refraction glass slabs and prisms, laser and ray-optics kits, interference and diffraction apparatus, and demonstration kits, all listed on stemaids.com on 28 August 2026.
Will lenses and lamp houses from this range fit any optical bench?
Components listed here are designed to be compatible within the STEMAids optical bench range (Optical Bench Ordinary, Optical Bench Half Shaper, and Single Rod Optical Bench). Buyers combining components from different manufacturers should confirm rail length and mount type before ordering.
What is the difference between the Optical Bench Ordinary and the Single Rod Optical Bench?
The Optical Bench Ordinary (Rs 1,340) uses a wider rail with separate uprights for each component. The Single Rod Optical Bench (Rs 1,940) keeps all components aligned on a single rod, which most schools find faster to set up and align during a standard practical period.
Do you supply apparatus for Young’s double-slit and single-slit interference experiments?
Yes. The Young Double Slit (Adjustable) is listed at Rs 840 and Young’s Single Slit (Adjustable) at Rs 640 on stemaids.com, both specified for senior-secondary and undergraduate wave-optics practicals.
What does an Optical Spectrometer cost and what is it used for?
The Optical Spectrometer is listed at Rs 5,990 on stemaids.com. It is specified for angle-of-minimum-deviation and refractive-index practicals using the Spectrometer Prism, and for spectral-line measurement at the senior-secondary and undergraduate level.
Is STEMAids a registered manufacturer of optical equipment?
Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for the full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
