We have been making wedges for a long time. Standard wedges as well as Risley Prisms (wedges). This particular unit is one we make in high volume. Thanks to our team and the tooling they designed, this product goes through production flawlessly. It is a 1″
We have been making numerous diameters below 1mm thickness for a few years now. The latest is this 8″ diameter x 0.90mm thick. As we tested the parts, we found we were getting great results of 1/8 TWE across the whole part and sometimes 1/10 wave. When you get down to this thickness, it’s so
We just completed another huge spherical lens! This 20″ huge piece has an almost 3″ center thickness. Made of Fused Silica, it is incredibly heavy. Just to give a little idea of how big it is, I placed a 4″ lens next to it. The polishing came out great, with a 1/4 figure over a 2″
Cosmo Optics just completed another round of these cool shaped first surface spherical mirrors. They range from 8″ to 32″ long. They are 15mm to 50mm wide and coated with a protected enhanced Aluminum. A first surface mirror, is an optical mirror providing superior accuracy for a number of applications. Unlike a standard mirror, a
In today Optics Spotlight we are going to be talking about lenses and the various ones Cosmo Optics can manufacture. Cosmo Optics can manufacture lenses from 1mm up to 48” in diameter, and currently is giving great deals on lenses between 15 – 200mm. Cosmo Optics can generate and polish lenses using our CNC’s or
In todays Optics Spotlight we are showing various windows manufactured by Cosmo Optics. In the photo to the right you will see three different kinds of windows. The small uncoated window in the back is made of Fused Silica and holds a tight wedge – less than 2 arc seconds. It’s diameter is 25.85 mm,
Double-Sided grinding and polishing uses planetary action that suspends particles in a liquid vehicle to abrade windows evenly from both surfaces. Because of the special way the machines grind and polish the windows, generally there is less thermal distortion, surface imperfections, and edge chipping. Double-Sided lapping and polishing (DSLP) holds the components in sprocketed or
SPIE Photonics West 2017
Cosmo Optics will be attending SPIE Photonics West this year. We are looking forward to seeing everyone there. Our booth number is #4611 in case you would like to visit. In case you don’t know a lot about us below is some information to catch you up to speed! We can manufacture the following optics:
