An LED collimator consists of a collimating lens and an LED emitter. The LED emitter is placed at the focal plane of the collimating lens. The collimating lens thus images the LED emitter into infinity. Mightex LED collimators employ a high-NA aspherical collimating lens for precision collimation and high light throughput.

Mightex’s deep UV LEDs cover the wavelength range between 240nm and 340nm.

LED collimators can be used as the light source in an illumination system. For example LED collimators can replace the standard lamp assembly in a microscope to provide stable, intense, and fast-modulated illumination. Typically the rest of the illumination optics will image the LED emitter onto the pupil of the imaging optics whereas the lens aperture on the collimator where intensity is uniform will be projected onto the object. In other illumination applications similar arrangement should be made to produce uniform and efficient illumination.

The LED emitters are mounted directly onto the metal base of the collimator which also features an integrated heat sink. This configuration minimizes thermal resistance between the LED emitter and the heat sink resulting in better heat dissipation. The collimating lens can be adjusted if needed for precise collimation. A locking ring fixes the lens position after adjustment. The collimators have been pre-adjusted in the factory.

The LED collimators include a 1.5-meter cable with two bare-wire terminals at the end. The light sources can be driven by Mightex LED controllers or other LED controllers and current sources.

WARNING: Due to low current ratings, certain Type-D deep UV LED’s should 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.

IMPORTANT : (1) LED’s can ONLY be driven by a constant-current source, and NOT a voltage source (e.g. a battery, or a 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.
