DUV-LED spot light source
L16665-100, C16659 series
Hamamatsu provides a DUV-LED light source that emits deep UV light at a wavelength of 280 nm.
This DUV-LED light source is capable of driving 4 heads independently, yet compactly designed to fit in the palm of your hand. Promising applications include sterilization by deep UV light with strong sterilization effect and various types of analysis, as well as UV adhesive curing and UV ink drying (tack removal) in combination with 365 nm UV light.

*4: The square symbol □ in each type number indicates a suffix that represents the specifications of the AC adapter.
・When no AC adapter supplied, no suffix is added. The user needs to prepare an AC adapter that outputs 12 V DC and 24 W or more.
In that case, EMC and safety testing should be performed by the user.
・When an AC adapter supplied, a suffix is added. A1: For Japan, A2: For U.S., A3: For Europe, A4: For China, A5: UK, A7: Thailand
IIn the case of C16659-0, the "-0" will be omitted and so the type number will be C16659.
*5: Input voltage to the controller should be 12 V ±0.5 V DC.
*6: Power consumption when 4 heads are operated.
Characteristics
Spectral distribution (Typ.) (*1)
Irradiance distribution (Typ.) (*1)
*1: The center of the external dimensions of the LED head unit may not coincide with the center of the irradiated light. Adjust the installation position as needed.
The shape of the irradiated light varies depending on the irradiation distance, for example, becomes close to a square.
There are individual differences in the irradiance distribution between LED head units due to variations in the emission intensity of LED elements.
