Dual Wavelength Products

In multi-wavelength light beams the dual wavelengths are diffractive optical elements used to combine two incident beams with different wavelengths into the same focal point. 
In particular, this focus combiner is used for combining CO2 laser focus and visible aiming beam focus into a single focal point. 
The Dual wavelength corrects the strong chromatic aberrations between a CO2 laser and its visible aiming beam.
This hybrid element,is based on a Plano convex lens with corresponding diffractive pattern on its Plano side.
The focal length for both wavelengths is determined during the design, according to the customer's application.

HOLO/OR is offering a Diffractive F-Theta lens with Dual Wavelength lens for medical treatments and scanner systems. This option eliminates the need to place the Dual Wavelength lens inside the scanner, and provides both focal shift and field corrections. These elements are represented by the part numbers with FT in the below table (as FT-001-AP-Y-A).
