High-Power LED Collimator Sources, 38-mm Clear Aperture
Collimated LED sources with a 38 mm clear aperture for microscope illumination: Type-A and Type-B emitters behind an interchangeable high-NA aspherical lens, from 340 to 980 nm plus white, bare-wire or connectorised for BLS controllers.
Manufactured by Mightex. Precisometer is a Mightex distribution partner: we quote, integrate and support Mightex products, with in-person support in the Netherlands and Belgium.
You need a collimated LED for a microscope infinity path with a 38 mm clear aperture; the aperture must match the microscope adapter or beam combiner.
Type-A and Type-B emitters cover the broadest wavelength list; for several watts of collimated output choose the Type-H super high-power version.
Based on: Mightex LCS product pages and microscope LED selection steps.

About the High-Power LED Collimator Sources, 38-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.
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.
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 form factor compared to other models. Please examine the installation drawings carefully.
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.
Additional interchangeable collimating lenses are available to produce different beam sizes with the same light source.

Reproduced from Mightex (official page), retrieved 2026-10-15.
Combine collimated LEDs of different wavelengths into one beam.
Notes from Mightex
(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.
Conceptual workflowFollows the four steps on Mightex’s microscope LED page: wavelength, LED configuration, LED controller, microscope coupling. It is not a verified configuration: we check how the parts fit your equipment before quoting.

LED source
Single wavelength, several combined, or switchable.
Collimated LED sources with an 11 mm clear aperture for microscope illumination: Type-A and Type-B emitters on an integrated heat sink behind an interchangeable high-NA aspherical lens, from 340 to 980 nm plus white.
Collimated LED sources with a 22 mm clear aperture for microscope illumination: Type-A, Type-B and Type-J emitters behind an interchangeable high-NA aspherical lens, from 365 to 980 nm plus white, bare-wire or connectorised for BLS controllers.
