IMPORTANT : (1) LED’s can ONLY be driven by a constant-current source, and NOT a voltage source (e.g. a battery, or an AC/DC power supply, etc.); (2) Please always verify LED’s current rating first before applying current to the LED, and please always make sure NOT to apply current that is above the LED’s current rating.

Mightex has developed the most comprehensive LED source solutions in the market. In order to make it easier for our customers to choose the best LED solutions for their specific applications, below is a brief LED source selection guide:

Step-1: Choose your desired LED wavelength(s) from the charts below:

WARNING: Due to low current ratings, deep UV LED’s can only be controlled using the following LED controllers:

In addition to using the correct LED controllers listed above, an appropriate current range must be set according to the LED’s current rating, in order to properly protect the highly delicate deep UV LED. LED damage due to over-driving is not covered by Mightex’s product warranty.

Step-2: Choose the best ‘beam format’ that suits your application.

In order to satisfy the specific needs of wide range of customer applications, Mightex offers an extensive range of beam formats with our LED solutions, including collimateduniformfocuseddivergentfiber-coupled, and lightguide-coupled LED sources. Microscope adapters are also available, in order to enable customers to mount the LED sources onto various microscopes. Please refer to the diagram below on how to choose the best beam format (and microscope adapters) for your specific applications.

If you require multiple wavelengths for your application, Mightex also offers a range of multi-wavelength LED solutions, as below:

(1) Wavelength-switchable LED’s with collimated output beam. With an optional lightguide adapter, the output beam can also be coupled into a liquid lightguide;
(2) Multi-wavelength fiber-coupled LED’s; and
(3) Multi-wavelength collimated LED’s using beam combiners. With an optional lightguide adapter, the output beam can also be coupled into a liquid lightguide. Various microscope adapters are also available for those customer who would like to couple the LED light into microscopes.
