EFL, Aluminum, New, Here is Newport 50331AL Parabolic Mirror, Off-Axis 1.5 in. Wave length Region Broadband. Moreover, by folding the optical axis and displacing focus away from mechanical axis, it is easier to install baffles block stray light paths outside aperture reaching detector. Mirror Shape Parabolic.
Material Aluminum. EFL, Aluminum, New This parabolic mirror is brand new but it has 3 small dents at the edge See photos. These standard off-axis parabolic mirrors are circular segments from one side of a full parabolic. Off-axis Design for Detector Applications: Compared with on-axis parabolic or ellipsoidal reflectors, the off axis mirrors do not have a central hole enabling light across entire aperture of mirror to be focused onto detector.
Diameter optic, such as mirror mounts, lens and rotation mounts. Aluminum for UV and visible applications bare Gold infrared. The mirrors are ideal for collecting and concentrating light onto high speed detectors, or collating output from broadband incoherent sources such as Leds super luminescent diodes.
