At Electro-Optix our products utilize high quality features, distortion-free optical grade acrylic shatterproof lenses, “hard coated when necessary,” and many available with bi-focal inserts for increased magnification and wider use and application. Our thermometers and hygrometers utilize high quality American and German made bimetal coils for precise readings and product longevity. We also utilize such features as Ultra-Violet inhibited resins and structurally reinforced plastics.

Where do you ship from… do you make your own products?
We ship from our factory in Pompano Beach, Florida. Most of our products are manufactured here in the USA at our factory. Some are manfuctured to our specifications and imported. We have been producing optical products/magnifiers in the USA for over 40 yrs.
What is distortion?
Distortion is an optical error (aberration) caused by the lens, that results in a difference in magnification at different points within the image.
What is a focal length?
Focal length is the distance from the object to the lens surface which results in the object being in sharp focus.
Why are your magnifiers made with optical
acrylic material instead of glass?
The main reasons for using acrylic instead of glass are lighter weight and durability. Between glass lenses and acrylic lenses, acrylic lenses weigh about one-half that of glass lenses this is very important with a hand tool such as a magnifier. Exceptional clarity and resistance to ultraviolet light, degradation and discoloration make the acrylic used in our lenses the standard in the industry. These resins are virtually unaffected by alkalis, hydrocarbons, non-oxidizing acids, salt water, photographic or battery solutions, and are inherently shatterproof and difficult to break.
What is an aspheric lens?
Aspheric lenses are specially made with non-spherical surfaces, corrected to eliminate spherical aberration, allows for less distortion, and improve focusing and collimating accuracy. It is a much more expensive lens to make, but the results are worth it.
What is a fresnel lens?
A fresnel lens replaces the curved surface of a conventional lens with a series of concentric groves molded into the surface of a thin, lightweight plastic sheet. The grooves act as individual refracting surfaces, like tiny prisms when viewed in cross sections, bending parallel rays in a very close approximation to a common focal length which if designed properly can be more efficient at gathering light then a standard lens.
This efficiency can be an advantage but there is a loss of image quality due to the visibility of the concentric rings in the lens surface. Higher grooved density can allow for higher quality images however. Because of these factors, fresnel lenses are a compromise between efficiency and image quality.
What happens if the magnifier is lifted too high over viewing image?
The magnified image will go out of focus and become distorted… it should be viewed at its “focal length.” Depending on the situation, the image can then become inverted and get smaller as the magnifier is moved closer to your eye.
What is a bifocal lens and what are the features of a bifocal lens?
A bifocal lens is a lens that has two different powers within it. The large portion of our bifocal lenses the lens has once magnification, and the smaller lens, which is molded as an integral part of the larger lens, has a different magnification of a larger power. This is similar to bifocal eyeglasses which have more then one magnification on the same lens… one for distance viewing and one for up close viewing.
What is field of view?
Field of view is the area seen through the magnifier. As the power increases, lens diameter and field of view decrease. At (5x) power the field of view is about 1 1/2”. At (10x) power it is about 1/2”. Usually, it is best to use low power for scanning larger surfaces and high power for scanning small areas.
