Lamda Guard Optical Filters – blocking light to protect vision

Lamda Guard products are engineered to selectively block light of specific colors or wavelengths to protect vision. They can be retrofitted onto existing surfaces to block light. Lamda Guard’s filters are lightweight, adhesive, and engineered to be highly transparent and neutral in color. They can be applied to any clear glass or plastic surface such as eyeglasses, protective goggles, laser safety glasses, visors, windshields, and cockpit windscreens. Since 2014, MTI has been working in partnership with Airbus to develop a solution to protect pilots’ vision from laser strikes. In 2017, MTI announced a new agreement with Airbus to co-develop, certify and commercialize metaAIR™.

How Do the Filters Work?

Metamaterials are comprised of tiny patterned structures that allows the optical filter to exhibit unique properties that are not found anywhere in nature. The precision of their shape, geometry, and arrangement allows the filters to produce unparalleled abilities that manipulate electromagnetic waves. MTI’s engineers have harnessed these properties to block light and channel it away from the target of light through its highly transparent and adhesive filter.

Lamda Guard’s optical  filters are engineered to interact with incoming light to block and deflect specific colors or wavelengths. Our products are engineered by our in-house team of scientists and experts in the field of nanotechnology. Our engineers accomplish this by designing the exact shape of each metamaterial, ensuring complete precision in the final result. 

Using our patented high resolution automated optical lithography, Lamda Guard can produce optical filters to your exact size.

Lamda Guard’s filters are also:

Adhesive

Lamda Guard’s filters are adhesive and can be adhered to the inside surface of a  windshield, eyewear, sensors, glasses or visors.

Transparent

Lamda Guard’s range of optical filter capabilities are engineered to be highly transparent and neutral in color. The clarity of the film makes it possible to use them at night 

Retrofit or Line-fit

Because the film can be cut to precise requirements, it can be retrofitted. The film is produced to specific size requirements, therefore the age, size, or shape of the equipment it will be applied to does not matter. It can also be applied to flat, cylindrical, or spherical lenses.

Custom Sized

Lamda Guard filters, including metaAIR™, are completely scalable. From centimeters to meters, the optical filters can be created to scale to the exact dimensions you require.
