HLD Achromatic Depolarizers
From $707 USD
Request a quoteProduct description
HLD achromatic depolarizers use two crystal-quartz wedges with optical axes separated by 45°; the source describes one wedge as twice the thickness of the other. The output polarization varies spatially, and broadband operation adds wavelength-dependent retardance. The source describes use in polarization-sensitive instruments.
The source lists cemented and optically contacted construction as category options. The one actual listed model, HLD33-025, is optically contacted, with Ø25.4 mm size and 7.5 mm thickness. No cemented model is inferred from the category options.
For monochromatic light, the source advises an input beam diameter greater than 6 mm for improved depolarization. For broadband light, it states that this beam-diameter restriction is not required. These are source usage conditions; no numerical depolarization efficiency or universal performance guarantee is supplied.
Schematic
Optical path reference; not a manufacturing drawing.
HLD33-025 lists a design wavelength range of 220–2500 nm. Standard products are uncoated; coating can be requested. The source states that a specific optical-axis alignment angle is unnecessary, but the actual input and measurement conditions remain relevant.
The model damage threshold is >5 J/cm², 20 ns, 20 Hz at 1064 nm. Keep that test wavelength and pulse condition attached to the value; do not extrapolate it across the complete listed band. Optical path reference; not a manufacturing drawing.
