About This Product
Through simple adaptations the instrument provides a broad beam for studying the general properties of X-rays, a single crystal Bragg diffractometer, a powder camera for Debye/Scherrer experiments and a fluorescent radiation emitter for the Moseley theory. The counter tube goniometer pivots from +10° to +130° and -10° to -130° relative to the beam axis, with angle coupling independent of the sample holder or in a 2:1 ratio. The notes for twenty-five experiments use the accessory set, which is available separately. Besides buyers across India, the Tel-X-Ometer can be exported to institutions in Zambia, Kyrgyzstan, Uruguay, Fiji and Suriname.
Frequently Asked Questions
Q1. How is radiation kept low?
Safety precautions are built into the apparatus, and the radiation level at 50 mm from any part of the surface does not exceed 0.5 mR per hour. The X-ray tube sits inside a thick-walled lead glass dome.
Q2. What accuracy do the diffraction set-ups give?
The single crystal Bragg diffractometer has a scale accuracy of 5 minutes of arc, and the powder camera for Debye/Scherrer experiments works to 30 minutes of arc.
