Mirrors

• Flat Mirrors - Flat mirrors do not form images. They are used to change the path of the optical system. Designers often use flat mirrors to fold a large system so that it fits within the envelope of a small product. Designers also use mirrors to invert images left to right or up and down. Flat mirrors come in a variety of shapes (square, round and rectangular) and sizes. JML's flat mirrors are available with many different coatings as well as substrate materials.

• Spherical Concave Mirrors - The optical power of a concave mirror is positive, like that of a convex refracting surface. Like a singlet lens, a concave mirror can produce a magnified or reduced, inverted image. The quality of the image produced by a spherical concave mirror is comparable to that obtained with a single lens element but the mirror surpasses the lens in its color performance (a mirror has no aberrations of color since all colors experience the same geometry of reflection.)

• Parabolic and Elliptical Mirrors - For narrow fields of view, a parabolic mirror will create nearly perfect images of distant objects due to its spherical correction ability. A contemporary application can be found in the collection optics for large collimated laser beams. Sometimes a designer only needs an off-axis section of a parabolic mirror. JML provides both Parabolic and Off-Axis Parabolic mirrors. JML also offers Elliptical mirrors. These mirrors have a unique imaging property stated in terms of its two foci: an elliptical mirror will perfectly image an object at one focus to its other focus. In practical systems, the elliptical mirror is not a complete ellipsoid; instead, a common elliptical mirror tends to be a small segment of the whole ellipse. An electrolytic process is used to form a sheet of nickel around a mold then a thin layer of rhodium is electrolytically applied to the nickel mirror after it has been released from its mold.

• Laser Mirrors - When laser engineers specify a reflecting surface they require precisely polished surface contours and high reflectance at specific wavelengths. For high-power laser applications, they also require coatings with high thresholds for laser-induced damage.

• Hot Cold Mirrors - Hot mirrors reflect infrared and transmit visible light. Cold mirrors behave in exactly the opposite way- reflecting visible and transmitting infrared. Hot or Cold mirrors can be used to overlay two beams of widely different wavelengths. One beam is transmitted through the surface of the mirror; the other beam is directed to reflect off the mirror.
