| Product Introduction

Achromatic Zero-Order Waveplate is a combination of two different birefringent crystal materials, such as quartz crystal and MgF2 crystal.Compared with the single wave plate, Achromatic Zero-Order Waveplate is relatively insensitive to Wavelength and temperature, and can achieve the desired delay in the broadband Wavelength range.Chromatic Aberration cancellation Waveplate are ideal for tunable, multi-band and broadband band applications.Our quartz-MgFCO₂, Achromatic Zero-Order Waveplate, the operating Wavelength range is greater than 300nm,λThe delay accuracy of the/2 Waveplate is betterλ/50,λ/4 Waveplate delay accuracy is betterλ/100.In addition, we can provide self-designed and manufactured super-elimination Chromatic Aberration Waveplate, delay accuracyλ/300,λ/2 Waveplate working range 325-1000nm or 600-2700nm,λ/4 Waveplate working range 310-1000nm or 600-2700nm.

| Optical Testing capacity

We use strict aspheric measurement methods to ensure that each aspheric mirror product processed meets the design requirements.Among them, Talysurf-PGI use contact method to test Fine Grinding products; CGH combined with Zygo Interferometer, CGH can compensate the wavefront error of the Optics element to be tested, realize zero-position interferometry, and obtain high-precision surface shape information; LuphoScan2603D uses non-contact interferometry to Optics and measure the Polishing aspheric surface.
