The T9DCS uses a double monochromator spectrometer with a fixed cell holder and a wavelength range of 185–900 nm. Users can define the bandpass from 0.1 to 5.0 nm in precise 0.1 nm increments. The system achieves stray light lower than 0.0001%T, ensuring highly accurate measurements. Control the instrument easily through USB, RS232, or Wi-Fi connections.
The Persee Analytics T9DCS Spectrophotometer employs dual monochromator technology for demanding UV-Visible spectroscopy applications. The optical design of both T9DCS and T10DCS ensures extremely low stray light characteristics (≤0.00004%T at 220 nm). This design supports an extensive photometric range of -8.0 to +8.0 Abs. With nitrogen-purged optics, the instrument performs measurements at deep ultraviolet wavelengths.
Users can adjust the slit continuously for precise spectral resolution control. An attenuating wheel allows accurate beam size adjustment to match sample requirements.
