Thread: Attaching diffuser film to Eagletac D25A2, swapable

    Default Attaching diffuser film to Eagletac D25A2, swapable

    I want to experiment with different diffusers in front of my Eagletac D25A2 light. I got a set of sample diffusers sheets from Luminit. These are approx 2" squares of diffusing material with a variety of different optical properties. (For example one might diffuse isotropically at 25 deg and another one might diffuse 25 degrees in one direction but only 5 deg in the perpendicular direction.) I would like to be able to cut out sections from these sheets, mount them somehow, and be able to swap the different diffusers onto the light so I can change between them.

    Can anybody suggest a reasonably robust mounting system that would allow me attach the diffuser material securely, but still swap between different sheets?

    Buy extra lenses and mount each different diffuser on its own lens.

    According to EagleTac 2012 catalog, there are several D25A2 models

    • D25A2 mini - bezel 17mm
    • D25A2 clicky - bezel 21mm


    Eagletac does not appear to offer filters/diffusers fitting their D25A2 models;
    I'm afraid you'll have a hard time locating third-party flat-surface filter/diffuser of the appropriate diameter.

    However, you may want to try:

    • Fenix AD401 flip-up diffuser - fits 20-21.5 mm
    • Xeno TW15V2 is a wand kind of diffuser made of POM resin - fits 21.5 mm


    Another alternative is to use a "dome" diffuser such as this one, which fits 20-24mm.

    Do the replacement lenses fit inside the front bezel? I couldn't quite tell what they were selling there.

    I have the D25A2 clicky. Note that I'm trying to get a limited amount of diffusion, not total diffusion, which is why I wanted to use the diffusing film. (I'm particularly curious about using the films that spread the beam in only one direction.) I wonder if I can buy a plastic pipe with ID = 21mm somewhere. Hmmm. I see nylon and fiberglass tubes with 13/16" ID available at mcmaster.

    Adrian,

    The diffusers mentionned above all slip over bezels of the indicated diameters.

    I don't own the light, but since they sell replacement lenses, I imagine you thread off the bezel ring, replace the lens, and thread the bezel ring back on. Try unscrewing the bezel ring to see.

    Brightview diffusers are sufficiently efficient. I have a sample sheet of their c-series and there's not much noticeable light loss. I've got some added on the glass of my Skyray King. GREAT flood.
