M-Series Cerium-doped Quartz TubeM-Series Cerium-doped Quartz Tube
M-series quartz is a high-purity semi-synthetic material doped with cerium. It effectively blocks ultraviolet transmission below 382 nm and is typically used where high surface quality, good homogeneity and low bubble content are required. These applications include:
Applications
Short-arc lamps
High-energy laser flash lamps
Continuous and pulsed laser lamps
Solarization-resistant lamps
Laser pump lamps
Product Features
M-series quartz is produced by an oxy-hydrogen flame fusion process. The raw material is made from high-purity synthetic quartz crystal.
It not only blocks part of the UV spectrum but also improves laser efficiency thanks to its fluorescence. The company's proprietary multi-stage steep production process draws the tubing without any contact with a die, effectively avoiding any surface contamination and achieving a near-flawless surface, no air gaps, extremely low bubble content and high homogeneity.
Because of the multi-step “free-drawing” production process, these tubes are available in many diameters and wall thicknesses, which also keeps the minimum order quantity low. The M series offers better UV blocking at around 250 nm.
