Broadband Light Sources

Innovative LED light sources for fluorescence microscopy.
Product Categories

These broadband light sources are incoherent optical sources, based around LEDs and doped fibre.

The main applications are:

  • Fluorescence Microscopy
  • Time-resolved Fluorescence
  • Förster Resonance Energy Transfer (FRET)
  • Photo-reaction lighting
  • Spectroscopy
  • Optical Coherence Tomography (OCT)
  • Acoustic Sensing
  • Fibre Optic Gyroscopes (FOG)

High Power Single Wavelength LEDs

High power, single precise wavelength LEDs with intensity control.

Kessil’s PR160L LED PhotoReaction Lighting series optimises photochemical reactions by improving speed, yield and efficiency.

CoolLED’s pE-100 series is a family of 20 different single-wavelength fluorescence LED illumination systems, perfect for routine clinical screening, electrophysiology or basic research applications.

Picosecond Pulsed LEDs

Sub-nanosecond pulsed LEDs are ideal excitation sources in spectrometer systems that do not require high spatial resolution.

Eight different LEDs with central wavelengths between 255 nm and 370 nm allow to choose a peak wavelength according to the needs of the application.

Their spectral and timing characteristics are also particularly suitable for biomedical applications, e.g., for the detection of labelled substances as well as naturally fluorescent amino acids like tryptophan or tyrosine.

LED Illumination Systems

Bluebox Optics and CoolLED specialise in the manufacture of illumination sources for fluorescence microscopy.

LEDs are replacing traditional gas discharge lamps as they are more stable, longer lasting, and energy efficient whilst offering superior safety and environmental features.

LED light engines offer multi-wavelength excitation from UV to NIR. The Bluebox Optics Niji has a unique reconfigurable mainframe that allows the user to change LEDs and Optical Filters in minutes.  These systems are for applications where speed is important as no shutter or filter wheel is required.  Optimise your excitation to match your experimental requirements with complete control.

White Light Systems provide a more economical option, where the excitation wavelength is optimised by optical filters within the microscope.

ASE Sources

OEM and benchtop ASE sources for the C band, C&L band and 1-micron band.  Output powers up to 19dBm, with options for gain flattening.

Applications such as Optical Coherence Tomography (OCT), Sensing & Spectroscopy

Superluminescent Diodes

nanoplus Superluminescent Diodes designed and characterised to fit your requirements.

Excellent performance at any wavelength from 760 nm to 2900 nm.


nanoplus introduces continuous-wave MIR LEDs (also known as ICLEDs) at customized wavelengths. Select any wavelength between 2800 nm and 6500 nm. The substrate-side-emitting devices display higher wall-plug efficiencies and maximum output powers > 1mW than previous MIR LEDs operating in continuous wave at room temperature. Operation in pulsed mode is, as well, possible, for low power consumption. nanoplus MIR LEDs are broadband, incoherent and cost-effective alternatives to lasers for many gas sensing applications in industry and research.

What's New?

We’ve recently refreshed our website, and we hope that you will find the changes to be a big improvement. We’ve worked hard to make it easier to navigate the site, and to find exactly what you need from among our vast and diverse range of products.

Missing e-commerce?

One thing that we’ve not carried over from the previous site at this time is the facility to order online for a select range of our products, which you may have been used to in the past. “Off-the-shelf” items represent a small part of our product range; most often a purchase requires a more in-depth discussion between our sales team and the customer to match the right product to the user’s application. For this reason we have focussed on making it as easy as possible to request a quotation from our sales team.

Please rest assured that we will get back to you with pricing promptly, and will work with you to make sure the products you buy are exactly what you need. Once you’re ready to order, our sales team will work through the process with you, to make it as seamless as possible.

Once you’ve selected all the items you’re interested in, by clicking “Add to Quote” on the product page, just click “View Quote Request List” or the icon in the top navigation bar, check your list, set quantities, complete your details and submit the form. Our sales team will respond by email, in a timely manner.

If you have any other questions in the meantime, please get in touch directly.
