<p>A thin film tin-oxide heater (10) including an annular inner heat region (12), an annular outer heat region (14), a first silver buss bar (16), and a second silver buss bar (18). The radius (r2) between the inner and outer heat regions is selected so that the resistance per unit square and power per unit area for the inner heat region approximates the resistance per unit square and power per unit area for the outer heat region.</p> |
