1. Conjugate Distance The conjugated distance of 185mm refers to the distance between the object plane and the image plane in the microscope system. This specific distance ensures accurate focusing and clear imaging. The working distance (W.D) of 7.63 mm allows sufficient space between the lens and the sample, making it easier to manipulate and observe without damaging the lens or sample. 2. 10x Achromatic Objective Lens The DM WJ002 biological microscope's 10x achromatic objective lens is designed to correct spherical aberration and chromatic aberration in the red and blue spectrum within the yellow green range. While chromatic aberration and field curvature remain, this lens provides adequate correction for general educational and hobby use, delivering routine performance. 3. Optical Lens Features This achromatic objective lens eliminates unwanted reflections and enhances contrast, producing images with minimal additional chromatic aberrations. The improved clarity and detail make it ideal for users requiring accurate observations without advanced corrective lenses. It enhances the viewing experience by delivering clearer and more detailed images. 4. RMS Standard Thread Featuring an RMS standard thread with a 20mm mounting size, this lens is compatible with most biological microscopes using the RMS thread system. Verify your microscope's thread size before to ensure proper adjustment and functionality. This compatibility ensures seamless integration with existing setups, eliminating the need for additional adapters or modifications.
