An imaging 1/2 meter monochromator/spectrograph. It has an f/8 aperture and a 2D flat field output for multi-channel use. It has a nominal resolution of 0.1 nm.Special toroidal mirror makes additional astigmatism correction. This spectrograph provides superior image qualityThe unique layout with toroidal mirrors is optimized for minimum coma while allowing high throughput and minimum stray light and vignetting. This option only applies to f/8 triple turrell with 50x50 mm grating holderPlease contact a technical sales member to discuss coupling options.For more information, please see the technical datasheet.
