Ramanor the ultimate in R a m a n Spectroscopy
• Stray light rejection of 10~"> at 20
cm-'
• Two holographic aberration-corrected concave gratings are the only optical surfaces in the monochromator cavities. • Both gratings are mounted on a common shaft for Zero tracking error. • Independent stepping motor controls for the wavenumher drive and each of the 4 slits. Scans can be run at constant bandpass with increasing throughput. • Remote panel with controls for manual or computerized operation.
We are justly p r o u d of our R a m a n o r H G - 2 . There is no other instrument that can equal its performance a n d y e t it is s i m p l e , f u n c t i o n a l a n d s t a t e - o f - t h e - a r t . R a m a n o r is designed for both routine and sophisticated research work with safeguards built in to make it virtually impossible to damage. Since 1819, J-Y Optical Systems has been setting standards for the industry. T h e R a m a n o r H G - 2 is only one example of our 150 years of experience in precision optics. F o r further information on R a m a n o r and our comprehensive line of m o n o c h r o m a t o r s and laboratory instruments, call or write today.
