Zusammenfassung:This disclosure relates to a surgical lighting device for generating a spot of light on a surgical site for use in combination with a fluorescence imaging device. The lighting device comprises a support structure, a subsurface which may be coupled to the support structure to seal the lower surface of the device while allowing light to pass through and a plurality of light sources emitting white light and placed between the support structure and the subsurface. The device further includes a plurality of NIR (near infrared) filters, each NIR filter being associated with a light source and being configured to substantially prevent the transmission of wavelengths within a wavelength band from 680 nm to 900 nm, while minimizing the change in the color temperature of the light spot.
