The Bausch & Lomb HIGH INTENSITY GRATING MONOCHROMATORgives more useable light with any source. Its unique optical systemhas only two internal reflecting surfaces instead of the conven-tional four. -You can get exactly what you want in a monochromator now.

And, you can be confident the modular "building-block" designwill let you interchange gratings, slits and light sources for future 2needs. There are five grating assemblies. Each covers a section of - n

the total range from 2OOm/1 to 3.2gi. You dial the desired wave-length and you're sure of reproducibility. Choose the appropriate C mlight source: Deuterium Arc, Tungsten Quartz-Iodine, high pres- m nsure or super pressure Mercury or a highly stable Xenon. Each one ais precisely aligned, prefocused and centered. 2

Bausch & Lomb offers a complete line of standard and cust-om z abuilt monochromators with the widest range of Certified-PrecisionGratings from the world's largest source. Write for Catalog 33-2098, Bausch & Lomb, 20746 Bausch St., Rochester, N. Y. 14602.
