Color Corrected Aspheric Lenses Reduce both Spherical and Chromatic Aberration

Posted by Bill Hill on

When precision and image quality are critical to the performance of an optical assembly, minimizing the number of lenses can become a critical design consideration.

What Determines the Wavelength of a Laser?

Posted by Jason Wickersham on

The world’s first laser came into the world on May 16, 1960, a little over 50 years ago. Invented by Theodore Maiman, a PhD experimental physicist, it changed the world as we know it. Because of it, millions of blind people are now able to see and machine tools are able to precisely drill holes ranging from a few microns to several millimeters in diameter in the hardest of metals.

Restoring Your Sight – Lasers in Eye Surgery

Posted by Jason Wickersham on

When the laser was first invented over 50 years ago, hardly anyone envisioned its use in eye surgery. Today, however, the laser has become an indispensable tool for many eye surgeons and has largely replaced the traditional scalpel in many procedures. High Power Laser Pointer are widely used, for example, to counteract the effects of diabetes, to reshape the cornea of the eye to improve sight and to remove cataracts that can impair vision.

Internal and External Healing – Lasers in Surgery

Posted by Jason Wickersham on

Many surgical procedures are difficult to perform using a traditional scalpel because they are located in hard to reach places, often requiring incisions in healthy tissue to access the area requiring surgery. Lasers, however, have made such surgery both easier and safer because a finely focused beam from a carbon dioxide gas laser can cut through human tissue easily and neatly. The surgeon can then direct the laser beam from any angle by using a mirror mounted on a movable metal arm.

Special Optical Coatings Enable Specialized Optical Functions

Posted by Jason Wickersham on

Precision optical components can be fabricated from many different materials, from crown or ordinary window glass to fused quartz to sapphire to mirrors, to meet the requirements of specialized optical applications. Sometimes, however, there is no single material capable of performing the desired function, so designers must turn to special optical coatings that enhance the capability of the substrate to which they are applied. Here are just a few examples.
