Allentown Optical's NEW Dip Coater Producing Superior AR coatings

Hard-coating by dip is the guarantee for premium scratch resistance applied to a lens. Machine, cleaning and hard-coating application adapted to the anti-reflection process are paramount for the market success. With the cleaning and hard-coating line CHC 20 , Allentown Optical Corp. provides a superior tool and a full solution integrated into our lab.

UV and AR 

Below is a comparison of Allentown Optical’s NEW AR COATINGS Vs. off the shelf AR. The graph shows the UV reflection off the backside of the lens. Notice how Allentown Optical’s AR levels off at 400nm, while normal AR increases rapidly and reflects back into the wearer’s eyes.

Ultraviolet A UVA 400 – 315 nm
Ultraviolet B UVB 315 – 280 nm

Refraction Index of Various Substances

In 1621, a Dutch physicist named Willebrord Snell (1591-1626), derived the relationship between the different angles of light as it passes from one transperent medium to another. When light passes from one transparent medium to another, it bends according to Snell’s law which states: that the angle of refraction is related to the

Wrap Prescription Sunglasses

There is high demand for sunwear in wrap form; it is estimated that as many as 25% of the prescription market is dispensed in highly curved lenses. Besides looking cool, wrap sunwear also provides better wind, dust, and sun protection than other lenses since they fit close and reduce light leak. However, the lens position

Transposition

Transposing a Rx prescription is simply converting the prescription from minus cylinder notation to plus cylinder notation. The optical properties of the prescription remain the same.

Procedure: 1) Add the cylinder power to the sphere power to arrive at the new sphere power.

2) Change the sign of the cylinder power.

3) Add or subtract
