Available with 11 mm, 22 mm, 38 mm, or 48 mm Clear Aperture.
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.
New Type-H super high-power collimator LED sources with 30 - 50 W emitters have been added to the product portfolio. These new collimator light sources produce a market-leading optical power output of up to 3.3 W, which is up to 5 times from our existing high-power Type-B collimator LED sources. The LED emitters are mounted directly onto the metal base of the collimator which also features an integrated heat sink and a cooling fan. 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 new Type-H light sources are larger in dimensions compared with existing Type-A and Type-B light source. Please examine the installation drawings carefully. Power supply for the cooling fan is included in the price of the LED collimator sources. 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.
Collimator LEDs are compatible with a large number of optical accessories/adapters:
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. This is useful for application requiring very high optical density such as fluorescence spectroscopy, or to focus LED light into a fiber or a light guide.
Additional interchangeable collimating lenses are available to produce different beam sizes with the same light source.
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.

Mightex BLS-series BioLED light sources are modularized fully-customizable turn-key solutions for optogenetics, fluorescence excitation, and other biophotonics applications. Precisely-timed and high-intensity light pulses are required in optogenetics experiments to activate channelrhodopsins (ChR2, ChR1 etc.) and halorhodopsins (NpHR) in order to excite and inhibit neurons. To meet these requirements, Mightex has developed a proprietary “IntelliPulsing” technology to allow BLS-series sources to output significantly higher power in pulse mode than what the LEDs are rated for in CW mode.
