Read moreKey Takeaways: Microscope objectives, vital for optical microscopy, come in two primary modes: finite conjugate and infinite conjugate. Infinite conjugate objectives, which project to infinity and require a tube lens, offer flexibility for incorporating optical components without sacrificing image quality, making them popular in scientific and industrial applications. Long working distance objectives are crucial, providing […]
Read moreKey Takeaways: Reflective microscope objectives are revolutionary in optical design, addressing challenges such as chromatic aberration and enabling diffraction-limited performance across a wide wavelength range. Their mirror-based construction reduces chromatic aberration and extends working distances, while maintaining stability and precision through uniform thermal coefficients. The two-mirror Schwarzschild objective exemplifies meticulous alignment for optimal performance. These […]
Read moreDesigning Off-Axis Parabolic Mirrors Off-axis parabolic mirrors, commonly referred to as OAP mirrors, are engineered to manipulate parallel light beams. Unlike standard flat mirrors, they leverage a parabolic section to achieve specific optical functions. Collimation: When a divergent light beam meets the OAP mirror parallel to its optical axis, the parabolic surface collimates the light, […]
