TMS305 Monochromator

The design of the TMS305 is an iteration of our popular TMc300 monochromator, including the capacity to mount larger diffraction gratings, to obtain maximum optical throughput, motorised entrance and exit port slits and an asymmetric Czerny Turner configuration for the avoidance of re-diffracted light.

The TMS305 is typically configured with a broadband illuminator to constitute a high irradiance UV-visible-NIR monochromatic probe.
