Laser Eye Surgery has now been used to correct vision for over four decades. The procedure has always involved accessing the corneal bed in order to reshape the cornea. But,the thickness of the corneal flap created to access the corneal bed has reduced significantlyover the years. Today, there...
When testing a lens on an optical bench (right now this is limited to me, apparently) it may be necessary to have glass of the appropriate thickness between the rear element of the lens and the MTF sensor. If it’s not done, the measuredMTF curveswill be falsely low. When testing a ...
CRYSTALLINE lensCATARACTPHACOEMULSIFICATIONCATARACT surgeryAims/Purpose: To assess the influence of cataract formation on the lens thickness (LT), anterior (ACS) and posterior (PCS) cortex space and nuclear thickness (NT). Methods: A prospective cross‐sectional study including patients seeking for ...

Image Credit:Sony In 2012, the first stacked CMOS sensor was created. Instead of wrapping around the photodiode, the circuitry is placed below it. Since it (partially) takes the place of a substrate used for structural rigidity, there's no added thickness. In fact, since then, improvements...
The glass is drawn into a very thin strand, with a thickness comparable to that of a human hair. The glass strand is then coated in two layers of plastic. By coating the glass in plastic, you get the equivalent of a mirror around the glass strand. This mirror creates total internal ...
