Pricing and Availability The Partial Waveplate Series is available for multiple order waveplates in 12.7 or 25.4 mm diameter mounting rings. The optical axis can be set to any location with respect to the cut flat edge of the waveplate. For single waveplates a charge of $100 is added to the base waveplate cost. This approach is also available on a custom basis for cemented zero order waveplates. For more information email sales@TowerOptical.com |
Tower Optical Corp. has announced the availability of a series of custom designed waveplates that allow systems with tight requirements for returned beam paths to share the same space as the transmitted beam paths.
The Partial Waveplate Series
The traditional waveplate is a Crystal Quartz disk which has been manufactured to provide a given retardation of a Laser beam at a specific wavelength mounted in an Aluminum ring. In certain system configurations the designer is constrained since the waveplate occupies too much space but only a small portion of the waveplate surface is used. The Partial Waveplate provides the solution by packaging a portion of the waveplate in the ring thereby making space available for other parallel optical beams. Tower Optical is offering both ½ and ¼ segments of waveplates packaged in mounting rings.
