Triple-LED
| The new fiber-coupled three color UV - Blue -
Green LED light source is an effective
replacement of multi line lasers and lamps in
many applications, such as spectroscopy and
fluorometry. Such popular wavelength mix as
365nm, 405nm and 515nm is now readily
available in a single MM fiber. Other wavelengths
combinations can be assembled upon request. The
LED driver enables CW operation with external
TTL modulation inputs for chopping operation of
each wavelength separately. Computer control
version with USB interface is also available.

Specifications
Emission wavelengths:
Any combination of three of the following wavelengths: 365 nm, 385 nm, 390 nm, 395 nm, 400 nm,
405 nm, 410 nm, 415 nm, 420 nm, 425 nm, 430 nm, 435 nm, 440 nm, 445 nm, 455 nm, 460 nm, 470 nm, 480
nm, 500 nm, 515 nm, 535 nm, 540 nm and 595 nm are possible. Other wavelengths in UV, Blue, Green, Yellow, Red and NIR
are also available per request. Please contact us for further details.
Power output:
Triple-LED power output is limited by the reciprocal fiber characteristics. Larger core and higher NA
will increase maximum power output, and vice versa.
The table below shows an example of the CW output power at three sample wavelengths for 2000ìm
core POF fiber:
| Fiber brand | Fiber type*¹ | Output @
365 nm
Power Typ.*² | Output @
405 nm
Power Typ.*² | Output @
515 nm
Power Typ.*² |
| Toray PGR-FB2000 | POF | 7 mW | 13 mW | 5 mW |
*1: POF – Polymer Optical Fiber. NA=0.5, Core diameter=2000 µm, Fiber length ~ 1m.
*2: Measurements were performed by Ophir Nova II power meter with PD300-UV head. The wavelength was set to
365nm, 405 nm and 515 nm for each wavelength separately. The values are for non filtered Triple-LED-365-405-515.
