Topaz Desktop Video Magnifier

The Topaz is a large CCTV used by our students at TSBVI.  It is available from Freedom Scientific.

The following description is from the Freedom Scientific website.  


  • Magnification to 77 times (on a 24-inch monitor)
  • Choice of widescreen 20-inch, 22-inch, or 24-inch monitors
  • Auto-focus camera
  • Accurate colors and even illumination with no glare to minimize fatigue
  • 33 screen color modes including high-contrast full color, true-color, and grayscale to fit your viewing needs
  • Over 8 inches of working space to write and work comfortably
  • Unique can and bottle holder holds round objects steady
  • Extra-wide reading table to smoothly glide large books and objects under the camera

Other Helpful Features

  • Adjustable monitor can be raised or lowered, tilted forward or back, or turned 90 degrees to the right or left
  • Freeze Frame to stop movement for close inspection of small objects or to keep your place
  • Focus Lock to maintain focus while writing
  • Find feature to quickly zoom out, find your place, and zoom back in to read
  • Reading Lines, Shades, and Masks to reduce eye fatigue and focus on what you want to read


  • The Topaz I use in class is a model that is slightly older, which is no longer available, but which has many of the same features as this model.
  • The ability to turn the screen up to a 90 degrees in either direction makes viewing convenient even if the CCTV is set to the side of the student. 
  • This is particularly helpful for students who use LP books and have their books on a bookstand or on the desk. 
  • I have had very few problems with the Topaz. 
  • Occasionally, there is a glitch that causes the light above the tray to turn off and it has to be reset, but I think this is because I inadvertently turned it off by pressing several of the buttons at once.
