TMS305 Monochromator

Product catalog summary

Overview: The TMS305 is a high throughput triple grating monochromator designed as an iteration of the TMc300 model. It features enhanced capabilities such as larger diffraction grating mounts, motorised slits, and an asymmetric Czerny-Turner configuration to minimize re-diffracted light. It is typically used with a broadband illuminator for UV-visible-NIR applications.

Key Features:

300mm focal length in an asymmetrical Czerny-Turner configuration.
Supports up to three diffraction gratings for optimal grating blaze efficiency within a 200nm-1100nm range.
Includes one entrance and one exit port with internal motorised slits.
Fully automated via USB 2.0 interface.

iteration of that of our popular rionocnromator 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. Key features include: • 300mm focal length single monochromator in asymmetrical Czerny-Turner configuration • Accommodates up to three diffraction gratings to permitting optimal...
