Collimated LED Sources - High-Power

Key Features

  • Aspherical collimating lens
  • High numerical aperture
  • High power (up to 15W)
  • Wide range of available wavelengths
  • Adjustable focus
  • Optional focusing module
  • Optional lightguide adapter

Description

A LED collimator consists of a collimating lens and a LED emitter. The LED emitter is placed at the focal plane of the collimating lens which images the LED emitter into infinity. 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. The LED emitters are mounted directly onto the metal base of the collimator which also features an integrated heat sink.

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. An optional focusing module can be mounted on the front of the LED collimator to focus light into a tight spot which is an image of the LED emitter. One of the applications with the focusing module is coupling LED light into a fiber or a light guide.

Multi-chip LED emitters have been added to the product portfolio. Some of these 7W to 15W LEDs have total optical power exceeding 1W, quadrupling the power of a single-chip LED. Models with higher powers (7W and higher) feature a cooling fan, and have a different formfactor compared to other models. Please examine the Installation drawings carefully. Power supply for the cooling fan is included in the price of the LED collimator.
