Spectral Lamp Power Supply with Lamp Holder
Spectral Lamp Power Supply with Lamp Holder (Product Code: SLE/PHY/298) is a compact spectral light source used to provide bright line-spectrum illumination for optics experiments and atomic absorption (AA) spectrometry in college and school laboratories. The lamp stands inside a black protective tube on top of the power unit, and turning the outer sleeve selects differently shaped apertures. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for physics and chemistry teaching labs.

What Is the Spectral Lamp Power Supply Used For?
Spectrum tubes are easy to show but often too faint for accurate spectrometer readings. This unit solves that by pairing a spectral lamp with its own supply in one compact housing, giving an intense line source that can be placed right against the spectrometer slit. Students use it to measure spectral line positions with a prism or diffraction grating, to find wavelengths, and to provide the monochromatic light needed for interference experiments.
The rotating sleeve is a practical touch: choosing a suitable aperture shape cuts stray light and matches the beam to the slit or optical set-up, while the black tube keeps glare away from the observer. For chemistry and instrumentation courses, the same bright source demonstrates the principle of atomic absorption. Switch on a few minutes before readings so the output settles, and let the lamp cool before handling it.
What to Specify When Ordering
- Number of units required.
- Which spectral lamp element or elements you need, such as sodium.
- Mains voltage and frequency at your laboratory.
- Whether spare lamps or a spectrometer should be added to the quotation.

Frequently Asked Questions
What is the Spectral Lamp Power Supply with Lamp Holder used for?
The Spectral Lamp Power Supply with Lamp Holder provides a bright, intense spectral light source for optical work such as spectrometer and grating measurements, and for AA spectrometry. It is far brighter than the dull light available from spectrum tubes.
How is the lamp mounted on the Spectral Lamp Power Supply with Lamp Holder?
On the Spectral Lamp Power Supply with Lamp Holder, the lamp sits inside a black protective tube standing up from the top of the power unit. This keeps the lamp shielded and directs light towards the experiment.
Can the aperture be changed on the Spectral Lamp Power Supply with Lamp Holder?
Yes, rotating the outer sleeve of the lamp cover on the Spectral Lamp Power Supply with Lamp Holder selects different shaped apertures. This helps match the emerging light to a spectrometer slit or other optical set-up and reduces stray light.
Which lamps and mains voltage suit the Spectral Lamp Power Supply with Lamp Holder?
Lamp element and mains rating for the Spectral Lamp Power Supply with Lamp Holder should be confirmed at the time of enquiry. Tell us the spectrum you need and your local supply through the contact page, and we will confirm the configuration.
