Quartz Low Order Waveplate

The Cost-Effective Workhorse for High-Energy Lasers

High Damage Threshold
Robust Single-Plate Construction
Superior Stability vs. Multi-Order
Exceptional Cost-Performance Ratio

Overview

Unmatched Stability & Precision

The Venuslab VLZW Series Zero Order Waveplates are designed for applications requiring superior stability against temperature fluctuations and wavelength shifts. Unlike standard multi-order plates, these components are constructed by stacking two quartz plates with their fast axes aligned perpendicular to each other.

This compound design effectively cancels out the thermal dependence, resulting in a highly stable phase retardation over a broader spectral bandwidth. They are the preferred solution for tunable lasers, diverse temperature environments, and precision instrumentation.
