IdealPhotonics' achromatic cemented doublet lens kit is a composite lens assembly made by cementing two different dispersive materials (such as N-BK7 and F2 glass). It is a core optical component specifically designed to correct axial chromatic aberration and improve the imaging quality of multiple wavelengths.The dual-material composite design precisely corrects chromatic aberration (visible light band), offering high transmittance and low wavefront distortion, making it suitable for high-resolution imaging and multi-wavelength laser systems.
