Zoom lenses target semiconductor test
Two zoom lenses, the MS-3 and the MS-509, measure 66 mm long and 25 mm wide and feature 3:1 and 1:1.5 zoom ratios, respectively. Standard optical magnification ranges are 0.13- 0.39X for the MS-3
and 1--1.5X for the MS-509. Used with a 2/3-in. CCD camera, the MS-3 field of view can reach as wide as 68 mm. Seiwa Optical Co, One Blue Hill Plaza, Pearl River, NY 10965; (800) 890-3333.
