Once the concave was done, we installed it and levelled it. Levelling is very important. Stueckle suggests that zero clearance at the back is the best, so it has to be perfectly level at the back and ...

Sunnybrook’s modular concave design also cuts waste, Foster says. With a typical concave “You throw 500 pounds of steel into the scrap bin for the loss of three or four ounces of mass when we call it ...

Image sensor for multilens panoramic imaging By combining the convex curved TFT *3 image sensor with multiple lenses, panoramic images can be captured by a simple “cropping and tiling” process.

Moreover, we confirmed with a white-light interferometry that the CMOS circuit can be deformed into a concave curve with radius of curvature of approximately 40 mm (Figure 7-7 (c) (1)).
