Arclight LED lights
The Arclight includes 3 LED lights
- Warm white light for ophthalmoscope
- Bright white light for otoscope / loupe
- Blue light for loupe and use with sodium fluorescein (NaFl) drops
Robust ‘daylight’ white LEDs give superb true-colour rendering of external tissues whereas softer ‘warm’ white light is better for examining the fundus. Because LEDs are low in infrared, ultraviolet, and short-wavelength blue light this gives both a safe and comfortable examination.
Different levels of brightness are available for both white lights.
Warm white light (ophthalmoscope):
- The highest brightness level is ideal for assessing the fundal or red reflex
- Lower brightness level works well for fundoscopy (viewing the back of the eye)
Bright white light:
- Highest brightness level ideal for otoscopy
- Lower brightness level ideal for using as a loupe to view the anterior segment (front of the eye)
Flashing lights:
- This setting acts as an attraction or fixation target – especially for children
