Q: How do factors like field of view and working distance impact objective lens design? A: Field of view refers to the area of the specimen visible through the lens and varies based on microscope type. Working distance, the distance between the lens and the specimen, affects ease of use and flexibility, particularly in high […]

Q: How does aberration correction affect microscope objective performance? A: Objective lenses are available in various designs with different levels of aberration correction, including achromat, plan achromat, plan fluorite, plan apochromat, and super apochromat. Choosing the correct level of aberration correction ensures optical precision within budget constraints. Back to top page

Q: How does numerical aperture (NA) impact microscope objective performance? A: Numerical aperture measures the objective’s ability to gather light and determines resolution. Higher NA results in superior resolution, allowing finer distinctions in images. NA = n × sinθa, where θa represents the maximum acceptance angle and n denotes the refractive index of the immersion […]

Q: What are microscope lenses and how do they function? A: Microscope lenses are glass components integral to microscopes, enabling the magnification of specimens. They work by altering the path of light rays passing through them, causing them to deflect towards the eye. This magnifies the image, allowing for detailed observation of microscopic objects. Back […]

Q: What are the crucial considerations when selecting a microscope objective? A: Choosing the right microscope objective is vital for optimal imaging quality and cost-effectiveness. Key factors to consider include conjugate distance, numerical aperture (NA), magnification, working distance (WD), immersion medium, and aberration correction. Back to top page

Q: What are the differences between Achromatic, Semi-Plan, and Plan objectives? A: Achromatic objectives feature a single achromatic lens, correcting color aberrations and providing a flat field in the central 65% of the image. Semi-Plan objectives offer an 80% flat field, bridging the gap between achromatic and plan objectives. Plan objectives provide superior correction for […]

Q: What are the differences between binocular, trinocular, and stereo microscopes? A: Binocular Microscope: Trinocular Microscope: Stereo Microscope: In summary, while binocular and trinocular microscopes are suitable for standard observation, stereo microscopes excel in tasks requiring depth perception and three-dimensional viewing.
