Performance
★Brilliance ≥3.7cd/m²
★Limit resolution≥2Lp/mm
★After-glow ≤3s, The time elapsing from the instantaneous luminance at which the excitation is stopped to 10% of the luminance is not more than 3 s.
★Under the excitation of X-ray, the main peak of the energy distribution of the emission spectrum is from 530 nm to 545 nm
Working principle
Sulfide fluorescent substances in the product under the excitation of X-ray can emit a wavelength of 530 nm to 545 nm (yellow-green) fluorescence which is more sensitive to the human eyes. By using of different tissues of the human body have different X-ray absorptivity, after the X-ray through the body and exposure to the product, the resulting image can help the medical staff examine and diagnose the patient's lesions.
Use and scope of application
Applicable for medial diagnostic x-ray equipment, are the medical diagnostic X-ray equipment Perspective system accessories.
