Beamsplitters
Beamsplitters are used to reflect a certain percentage of incident energy, while transmitting the remaining energy. In most cases, beamsplitters are angle, wavelength, and polarization sensitive.
Most beamsplitter coatings are highly polar... Read More
Biconic Lenses
Biconic lenses have two different radii on one surface. It is possible to make a biconic lens with spherical curves or aspheric curves, depending on the application and need to eliminate aberrations. Biconic lenses are used to produce an elliptica... Read More
Biconic Mirrors
In many applications, spherical mirrors, cylindrical mirrors, and parabolic mirrors help shape the laser beam. Biconic mirrors -- or the more general toroidal mirrors -- can combine two separate optics into one.
Biconic mirrors have two di... Read More
Focused Flat-Top Doublets
II-VI designs a simple form lens to convert a Gaussian mode to a flat-top intensity profile.
Converting one beam mode to another type is always a difficult process. There are different products to address this problem, including diffractiv... Read More
Long Working Distance Off-Axis Parabolas
In Ithe past, the working distance (WD) of off-axis parabolic mirrors was limited to the two-axis diamond-turning lathe’s swing diameter. Today, II-VI routinely produces long working distance parabolas with any turning angle using slow tool serv... Read More
Optical Arrays
Certain optical system designs require multiple optical elements to be positioned accurately as an array. In the past, individual optics were produced and connected to a common substrate, which posed significant position and alignment challenges. ... Read More
Reflective Beam Integrators
Reflective beam integrators are widely used in high-power lasers for welding, cladding, and heat treating applications. Faceted integrators focus a high-power beam to a relatively flat-top beam with a size and shape that is equiva... Read More
Transmissive Beam Integrators
Transmissive beam integrators are used with laser applications requiring a relatively large, focused flat-top intensity. Faceted integrators focus a high-power beam to a relatively flat-top beam with a size and shape that is equivalent to the indi... Read More
Vortex Lenses
The vortex lens is unique because it has spiral-phase steps machined into the curved surface. This spiral pattern controls the phase of the transmitted beam. When the spiral steps are machined into a curved lens surface, they prod... Read More
