  • IR filter band on uCAM-III

    Hi Kevin,

    I am using the uCAM-III for predominantly night time use (short distance and low resolution) that requires external IR lighting in the 860nm band or 950nm band.
    Does the 56 degree and 76 degree lens allow for passing on IR light in the 860 nm bands? what about the 950nm band?
    What band passing frequencies does it currently have.
    Would it have band passing as in diagram (pass band1 400nm to 600nm, pass band 2 800nm to 900nm, light blue curve)
    Do you have information on sourcing IR filters that fit into S Mount lens ?

    Hello geraldd,

    Referring to this thread post: https://forum.4dsystems.com.au/forum...-ir-cut-filter
    The uCAM-III has a built-in IR cut filters, 860nm and 950nm is not visible at all.

    If you want to use the camera for night-time photography, you may want to consider or look for an S-mount lens which covers the bands you need
    or just pick a lens without an IR-cut filter then apply a separate filter.

    We have not tried using lenses other than those that we sell. However, we don't see a reason why other S-mount lenses won't work with the uCAM-III.

    Best Regards,
    Kevin

      Hi Kevin,

      Thanks for the feedback. Can you provide a source for the S mount lenses for the uCAM device or point me in the right direction.

        Hello geralld,

        Perhaps you can try and check these sites:

        https://www.ccdcmoslens.com/product-...-board-lenses/
        http://www.megapixellenses.com/suppl...5-board-lenses.

        You can ask and contact them about the requirements you need on IR filters.

        I hope this helps.
