Lightguide collimators:

Lightguide collimators are used to either couple light from free space into a lightguide or collimate light from a lightguide to form a collimated (parallel) optical beam. Lightguide collimators are key components with numerous applications. For example, a lightguide collimator can project light from a lightguide into a uniform spot in free space.

High-numerical-aperture aspherical lenses are used for precise collimation and maximum light throughput. The collimator features adjustable focus from ~100mm to infinity. Various lightguide ferrule diameters are supported. Customization is available for other ferrule diameters.

The full field of view (FOV) or full divergence angle can be calculated as FOV = 2atan(D/2f), where D is the lightguide core diameter and f is the focal length of the lens. Alternatively, the linear field of view on an object placed at a distance L away from the collimator is D(L/f).

Model: ACC-BC25-011.

Currently, Mightex’s multi-wavelength beam combiners can only be used to DIRECTLY combine 22mm-diameter Collimated LED Sources. For 11mm-diameter collimated LED sources, (as shown below) a mechanical adapter (P/N: ACC-BC25-011) can be used to attach the LED sources to the beam combiners, before the 11-mm diameter collimated LED sources can be combined.

Mightex Microscope Device Adapter — **Adapter for converting M27 thread to C-thread**

Model: ACC-LCS-27C

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.
