Optical Parabolic mirrors reflective off-axis parabolic mirrors

Off-Axis Parabolic Mirrors are mirrors whose reflective surfaces are segments of a parent paraboloid. They achromatically focus a
collimated beam or collimate a divergent source, and their off-axis design separates the focal point from the rest of the beam
path. The reflective design eliminates phase delays and absorption losses introduced by transmissive optics and makes these well
suited for use with femtosecond pulsed lasers.

Example with BK7 material：These N-BK7 Meniscus lens are available uncoated or with one of five antireflection coatings (-A, -AB, -B, -C, or -D), which reduces the amount of light reflected from each surface of the lens (see the Selection Guide table below for coating option). Since approximately 4% of the incident light is reflected at each surface of an uncoated substrate, the application of an AR coating improves transmission, which is important in low-light applications, and prevents the undesirable effects (e.g., ghost images) associated with multiple reflections. Having optics that are AR coated on both surfaces is particularly desirable for applications utilizing multiple optical elements. Please see the Graphs tab for additional coating information.
