System Sub-Assemblies & Components > Heating & Bakeout

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 mounted in an electropolished stainless steel 'catenary' reflector. The lamps have a color temperature of 3000K indicating ~90% of the total energy is emitted at wavelengths between 0.7 and 10 micron (peaking at 0.9 micron). The lamp’s average life is 2,000 hours. Arrays of multiple lamps are also available in triangular and other configurations.

NOTE:

• * Calculated using: Planck's law of black body radiation
• ** Calculated using: Blackbody Radiation Applet
