"Non-contact infrared thermometer custom-designed for accurate preform temperature measurements in optical fibre manufacture.
Optimised for precise preform temperature control in vapour deposition processes, AMETEK Land’s Vapour Deposition Thermometer delivers a critical measurement for production of low-loss, high-bandwidth optical fibre.
VDT enables exact sighting onto the rotating preform for an accurate surface temperature reading, critical in controlling fibre strength and transmission quality. This ensures an efficient, high-yield process with less costly scrap product.
Only a non-contact infrared thermometer technology is able to achieve the precise surface temperature measurements required for the process. VDT’s 4.8-5.2µm waveband measurement means the preform is opaque and the measurement unaffected by flames, ensuring exceptional accuracy.
Able to operate as a standalone device or as part of a multi-thermometer system linked by our System 4 Landmark Graphic signal processor, VDT is ideal for vapour deposition processes in the glass industry."
