Pocket-size microscopes have 30X or 60X to 100X zoom magnification with brilliant illumination. A switch slides a focused condenser and blue filter over the light to produce a bright beam closely resembling daylight for optimal color detection. A single control produces a smooth and rock-solid focus. Magnifiers are ideal for quality control, field use, electronics, metal analysis, clinical analysis, and plant study applications. Or for anyone who needs to view at high magnification in bright light, true color, high contrast, and with a sharply defined focus. Case is chemical- and shock-resistant ABS plastic. Dimensions: 51/2L x 11/2W x 7/8 in.H (140 x 38 x 22mm). 3 oz. (85g).
