  • Newport 05RP02-40 Zero-Order Half Wave Plate 1550nm

    $299.00

    Newport 05RP02-40 Zero-Order Quartz Half Wave Plate 1550nm

    OD: 12.7mm
    CA: 8mm

    Newport Description:
    The 05RP02-40 is a (lambda)/2 Retardation Zero-Order Quartz Wave Plate, 12.7 mm in diameter and optimized for 1550 nm. Zero-order wave plates are temperature insensitive phase retarders for moderate bandwidth applications. These zero-order wave plates are constructed of two quartz plates, air-spaced to allow for use with high-power lasers, in a standard 12.7 mm or 25.4 mm diameter housing for easy mounting into a holder. Zero-order wave plates are moderately insensitive to wavelength change, which makes them ideal for laser diode or tunable laser applications. Typical zero-order wave plates have a temperature coefficient of 0.0001 (lambda)/degC.

    Listing is for single optic with mount.
