MS 3501, MS 3504 MS 3501i, MS 3504i - ILPhotonics.com

0,35 m MONOCHROMATOR - SPECTROGRAPH
Each Model is an F/3,8 instrument with a focal length of 350 mm.
The optics in the Models MS3501i and MS3504i correct for the astigmatism to enable the use
of the devices in multi-track spectroscopy as well as operation with low-light sources in
Emission, Fluorescence and Raman Spectroscopy.
Models MS3501, MS3501i use one easy-changeable or fixed grating,
Models MS3504, MS3504i use a four-grating turret to provide automatic grating switching.
FEATURES
High throughput
Complete computer control
Four-grating turret (for MS3504 and MS3504i)
with automatic grating switching
Low stray light and no re-entrant spectra
Continuously automatically or manually
variable slits
Two flat field output ports with automatic port
switching allow simultaneous mounting
of different detectors
Original software Win’9x/ME/2000/XP
