Substrate Quartz Lamp Heaters
 |
Act as both bakeout heaters and sample heaters.
Features
- Mount inside a vacuum chamber to raise the temperature of substrates
- Because they produce infrared radiation and ultraviolet light, they clean nearly all molecules adhering to the substrate’s surface through electron excitation and molecular vibration
- Unit can operate safely in an oxygen backfill
- Can be used in place of blanket heaters or panel ovens
- Save time and power—heat radiates directly to the critical surfaces
- Heater can achieve temperature uniformity of better than ±10% across a 4" diameter substrate
- Black box design ensures efficient heat containment, minimizing secondary heating of other components
We offer single lamp assemblies, approximately 4" in length. Each uses a 500W lamp, producing 9,500 lumens. Lamps are mounted in an electropolished stainless steel "V" reflector with a high-temperature, fabric-covered power cable. Our lamps have a heat output of approximately 200° C with an average life of 2,000 hours. Arrays of multiple lamps are also available in triangular and other configurations.
