Half Dome Mirror

A half dome mirror is an excellent security mirror to view down aisles, hallway intersections, entrances and as a safety mirror to see around corners. A half dome provides 180 degree view. They are a great security mirror to discourage theft in retail stores and will prevent collisions when used as a hallway mirror for 3 way intersections. May be paired with quarter dome mirrors for use as a safety mirror in warehouses and a security mirror in production areas. 

 

  • Blind spot convex mirror for hallways and aisles
  • May be wall or ceiling mounted
  • 180 degree mirror view

A half dome is fundamentally half of a full dome mirror. The lens has a convex design and offers 180° view . A half dome mirror is intended to mount flush against a flat surface. Often they are referred to as hallway safety mirrors because they are positioned at 3 way intersections to avert collisions or detect the presence of people or objects in sensitive areas. They are most often mounted at the top of a wall snug to the ceiling but can be hung in any position to provide you with the visibility needed to eliminate blind spots.  

 

 

 

  • Provides blind spot coverage along hallways, corridors, aisles & blind corners
  • Can be used where there are no mounting options for a round convex mirror
  • Wall or ceiling mount 

 

 

The outer rim on the outside edge of the half dome is referred to as the flange. This surface allows for simple and easy mounting by pre drilling holes around the flange then using screws to fasten the dome to the ceiling.  Half domes with hardboard and steel backing options have metal clips attached to backside of the mirror. The clips allow for alternative fastening with wire or chains. Backing materials will also allow for mounting with other materials such as doubled sided tape, velcro, construction adhesive, etc.  

 

Half Dome Backing Options:

 

  • Lens Only - Most economical and most common ordered half dome. No backing materials. Mounts with pre drilled holes in the flange. 
  • Hardboard backing - Sturdyfiber board. Increased rigidity. Hanging clips attached to the back of the surface for mounting with wire or chains.
  • Galvanized Steel - Heavy duty non-porous surface for industrial or outdoor applications. Clips attached for mounting. 

 

Half Dome Lens Options 

 

  • Acrylic Lens - All-Vu® acrylic shatterproof lens. Durable enough to accept mild to moderate impacts without failure. Will not leave hazardous shards characteristic of glass when broken. Most popular and economical lens material.

Half Dome Operative Range:

 

The distance at which images are reflected from a dome mirror is considered infinite. This means that it will reflect everything within its scope; however, the articles farther away from the mirror will appear too small for recognition. Domes are most beneficial when employed in wide open areas. Each size or diameter dome has a unique, effective viewing distance. Adverse conditions such as low light, poor vision, obstructed views, improper mounting, etc., will affect these calculations.  

 

  • 12" Half Dome - clearly view objects up to 12' away
  • 18" Half Dome - clearly view objects up to 20' away
  • 26" Half Dome - clearly view objects up to 30' away
  • 32" Half Dome - clearly view objects up to 36' away
  • 36" Half Dome - clearly view objects up to 42' away
  • 48" Half Dome - clearly view objects up to 55' away

 

If your viewing distance exceeds the above referenced guidelines or if you need to see images in greater detail than a circular convex mirror is strongly suggested. Objects appear much smaller and in marginal detail because of the a) curvature of a dome lens and b) its compact convex design.
