Off Axis Parabolic Mirrors

PBL Optics’  off axis parabolic mirrors(also known as OAP mirrors) or parabolas are one of aluminum or copper mirrors made by high precision machining equipment.  Due to the principle of a parabola, they can be enabled parallel andcollimated incident light or collimated terahertz waves to their focus, and they can also convert THz waves from apoint light source into parallel-propagated THz beams. Their total reflection design eliminates the phase delay andabsorption losses from projecting.They are widely used in femtosecond laser, UV, visible, infrared and terahertz applications.

Coatings for off axis parabolic metallic mirrors(also known as OAP mirrors)  are available in four types:

UV-reinforced aluminum coating (250-450nm);

Protected silver coating(450nm-20μm);

Protected aluminum  coating (450nm-20μm)

Protected gold coating or bare gold coating (800nm-20μm)

Available offset angles for OAP mirrors: 15 degrees, 45 degress and 90 degrees
