Vacuum level compatible up to 1 Pa! A sealed window that enables the connection of microwave equipment to reduced pressure loads.

The airtight window "TW-WRI22-ALQ" enables the connection of microwave equipment to a reduced pressure load by being inserted between the waveguide and the load. 【Features】 ■ Enables connection to reduced pressure loads ■ Supports vacuum levels down to 1 Pa ■ Prevents the intrusion of gases and other substances into the waveguide from the load side ■ Temperature sensor attachment available (optional) *For more details, please refer to the PDF document or feel free to contact us.

basic information

【General Specifications】 ■Dimensions: W161 × D17 × H106.5 [mm] (excluding protrusions) ■Weight: 2.0 kg or less ■Waveguide standard: WRJ-2 ■Connection flange standard: BRJ-2 ■Window material: Quartz (5t) ■Frame material: Aluminum ■Sealing method: Silicone O-ring Operating conditions: Ambient temperature 0–40℃, Humidity 35–85% 【Electrical Specifications】 ■Frequency range: 2455MHz±20MHz ■Power handling capacity: 6000W (CW) (under matched load) (please refer to the notes below) ■Vacuum conditions: Vacuum level of 1Pa or less (please refer to the notes below) ■Input VSWR: 1.33 or less 【Notes】 - The power handling capacity as a waveguide is 6000W, but when microwaves are introduced in a vacuum environment, plasma may ignite on the low-pressure side of the window material, which can hinder the introduction of microwaves or cause issues due to heat (such as O-ring burning). - The conditions for plasma ignition are determined by the balance between the "output value of the introduced microwaves" and the "vacuum level on the load side," so users are responsible for determining these conditions.
