Quarter Dome 90° Indoor Mirror

Quarter dome mirrors are ideal for broad view observation providing over 90 degrees of vision. For most applications the recommended choice is the standard convex mirror. Quarter domes are ideal when physical constraints limit the area available for the mirror. Quarter domes are discreet and fit between the ceiling and corner junction of 2 walls and provide 90 degree vision horizontally and directly below the mirror. There are 2 versions available; this version (acrylic) is for all general purpose applications and for indoor use only. We also provide a fully framed version with unbreakable polycarbonate or stainless steel mirror for high security applications; correctional centres, protective wards and the like. For these applications please see the page on high security products.

What size mirror should I use?

There are only 2 sizes available. The smaller mirror is suitable for narrow corridors (blind corners) or small enclosures (lifts or small rooms). The larger mirror is more suited to standard size rooms or corridors. For larger areas again consider a convex mirror as opposed to the quarter dome mirror as the better choice.

Can I use this mirror outdoor?

This style of mirror is for indoor applications only. Being a 'domed' shape, the mirror curvature is much deeper than a normal convex mirror and is necessary for creating the wider field of view. This style of mirror should be viewed at close range to obtain the best results which excludes its use as a practical mirror for outdoor. The image size and definition will be too small considering the larger distances normally expected in these situations.
