Exploring the forefront of modern microscopy, the 50X long working distance objective lens stands out as a true innovation. It delivers exceptional magnification and precision for biomedical research and high-accuracy testing applications. Built with an infinite conjugate design, the lens integrates seamlessly into diverse microscopy systems. Optimized for near-ultraviolet (NUV) wavelengths—particularly at 355 nm—it provides outstanding transmittance and superior achromatic correction. With a numerical aperture (NA) of 0.65 and an extended 10 mm working distance, this lens excels in industrial and scientific imaging, offering consistent performance across the entire field of view.
At the cutting edge of microscopy innovation, the 50X infinite conjugate long working distance objective lens serves as a versatile tool across disciplines such as biomedical research, precision testing, and materials analysis. Its powerful magnification enables crystal-clear visualization and high-resolution examination of microscopic biological and material structures.
Engineered to meet the evolving demands of modern science, this lens delivers precise observational capabilities across a wide range of applications. Its infinite conjugate optical system enhances flexibility, ensuring easy integration with various microscopy platforms and accessories. Designed for professionals in biology, medicine, and materials science, it empowers researchers to push the boundaries of scientific discovery and technological innovation.
Engineered with precision, the 50X objective lens is optimized for the NUV (Near Ultraviolet) spectrum, making it particularly suited for near-ultraviolet laser applications. The 0.65 NA supports a 10 mm working distance, offering the flexibility needed for industrial and processing tasks.
Achieving such an extended working distance with a high NA requires meticulous optical design, including careful manipulation of light paths through the front and rear lens groups. These objectives often incorporate specialized glass materials and complex optical configurations, resulting in a more sophisticated design compared to conventional microscope objectives.
Performance evaluation centers on dispersion spot radius and modulation transfer function (MTF) analysis. For this model:
Across the entire field, the objective achieves near-diffraction-limited performance with exceptional imaging consistency when tested using a single-point light source.
A defining strength of this objective lies in its optimized performance at 355 nm within the NUV band. Despite the challenges associated with material limitations in NUV calibration, this lens achieves 50% transmittance and excellent achromatic correction. It pairs seamlessly with eyepieces featuring a 24 mm field number and a 0.48 mm object field of view, ensuring uniform sharpness and color fidelity across the entire image plane—meeting the stringent flat-field requirements for professional microscopy.
Carefully designed for superior optical precision, the 50X objective lens combines high numerical aperture, broad field coverage, and a 10 mm working distance. Operating within 355–532 nm, it spans the NUV range and supports precision laser processing at both 355 nm and 532 nm, while maintaining impressive imaging quality at 365 nm and 405 nm.
Representing the pinnacle of specialized optical engineering, this lens sets a new standard for high-performance microscopy, addressing the most demanding requirements in both research and industrial applications.
