Innovative flat angle eyecup for stereo microscopes designed for comfort, protection, and compact storage. The foldable flat angle construction makes it easy to collapse the eyecup when not in use without reducing protective coverage during sessions. Key benefits Foldable flat angle design for compact storage and quick deployment. Precise fit for 40 to 42mm interface eyepieces with a 44mm diameter for full coverage. Soft rubber construction for long term comfort and reduced eye strain. Non slip grip for stable positioning during detailed work. Creates a barrier between the eye and the lens to prevent direct contact and maintain clear, focused views. Specifications and performance Compatibility: Intended for eyepieces with a 40 to 42mm interface. The 44mm outer diameter gives ample coverage while maintaining a snug fit. Material: soft rubber that conforms to the face, improves comfort over extended use, and offers a secure grip. Function: Ergonomic shape reduces stray light and prevents smear or oil transfer to lenses, helping maintain consistent image clarity. Practical use scenarios Laboratory analysis and research where prolonged observation is required and eye comfort matters. Classroom and training environments to help students maintain consistent viewing posture and reduce distraction from stray light. Electronics inspection, watchmaking, or entomology where steady, closeup observation and protection of the eyepiece are important. Why choose this eyecup This eyecup combines a practical foldable design with precise compatibility and soft, durable material to improve comfort and protect both the user and the eyepiece. It is a straightforward accessory to enhance routine microscopy work for students, technicians, and professionals.
