McPherson - Model 231 - One Meter Seya-Namioka Monochromator - Datasheet

The 1.0 meter focal length Seya-Namioka uses simple grating rotation to scan wavelengths. An angle of 70° 15` subtends the entrance and exit slit arms. The focal length provides excellent resolution and a lot of work space. Stainless steel construction makes this design suitable for use with high vacuum and contaminant free experimental chambers or microchannel plate intensified detectors.
