1/4m Imaging Spectrograph, Motorized Slits, Single Axial Output Port
The MS257-S-MT-A 1/4m imaging spectrograph is a completely automated instrument with the high performance and versatility to satisfy most spectroscopy applications. The MS257 is an F/3.9 instrument with a focal length of 257.4 mm. Stray light is negligible and there is no re-entrant spectra. This instrument holds up to four diffraction gratings and controls up to two filter wheels, making it ideal for extended range wavelength scans. It can be configured to switch between two input sources using the optional 77765 motorized beam steerer, further increasing its capability. A motorized slit allows users to adjust the slit width via computer control. The automatic bandpass feature maintains consistent resolution over an entire scan, simplifying data collection and analysis. The axial output port configuration eliminates the need for an extra built-in reflector in the light path to turn the output beam, making it a favorite choice for simplicity and high throughput. The MS257 supports USB and RS232 communication, and GPIB with the use of optional accessory 77793. Select up to four gratings when ordering this spectrograph.
