Six-position stepper-driven filter wheels that switch filters automatically on Omni-λ monochromators and spectrographs.
The SD25 is a compact six-position filter wheel for 25 mm diameter filters with a 22 mm clear aperture. A stepper motor turns the wheel under command of the monochromator/spectrograph controller, so filter changes are handled together with the wavelength scan in the control software. Versions are available empty or pre-loaded with filter sets for ranges from 200–1500 nm up to 1300–12000 nm.
Key Features
- Six filter positions for Ø25 mm filters, 22 mm clear aperture
- Stepper motor drive controlled through the monochromator/spectrograph controller
- Integrates with Omni-λ series monochromators/spectrographs and their control software
- Empty version (SD25 / SD25-R) for user-fitted filters, or pre-loaded filter sets
- Pre-loaded sets cover 200–1500, 200–2000, 400–3000, 650–5000, 800–8000 and 1300–12000 nm
- SD25 series fits Omni-λ300i/500i/750i; SD25-R series fits Omni-λ200i and the SAC-FLUO sample chamber
Typical Applications
- Automatic filter switching during monochromator wavelength scans
- Suppression of higher diffraction orders in grating instruments
- UV to mid-infrared spectral measurements
- Automated spectroscopy systems
