Achromatic lenses, designed to reduce chromatic aberration and minimize spherical aberrations, play a crucial role in various optical applications. These lenses are particularly valuable in fields such as fluorescence microscopy, image relay, inspection, and spectroscopy. Typically, achromatic lenses are constructed by either cementing or housing two elements together, resulting in smaller spot sizes compared to singlet lenses.
Enhanced Color Correction: Superior to traditional achromatic lenses.
Improved Aberration Correction: Comparable to precision-machined aspheric lenses.
Project Overview: Retinal Detection
In the medical field, specifically for detecting the human retina, the need for high transmittance in achromatic lenses was paramount. Achromatic lenses generally consist of a positive low refractive index (glass) element and a negative high refractive index (quartz glass) element. For this project, we utilized H-ZF & H-LAK high-transmittance glass to meet the stringent transmittance requirements. Special treatments during processing and polishing were employed to satisfy the specific needs of medical applications.
