The Concave Lens with a diameter of 75 mm and a focal length of -20 cm is a high-quality optical component designed for precision experiments, demonstrations, and educational applications. Made from premium-grade optical glass, this lens is engineered to deliver superior clarity and light transmission, making it ideal for use in physics labs, optical instrument testing, and academic environments. Its concave structure ensures the divergence of parallel light rays, forming virtual images that are essential in understanding the fundamentals of optics and lens behavior.
Description
Concave Lens Dia 75 mm FL 20 cm for Light Divergence Study
The Concave Lens Dia 75 mm FL 20 cm supports clear understanding of light divergence and virtual image formation in physics classrooms and laboratories. Its precisely manufactured glass surface and negative focal length allow students to observe how light rays spread after passing through the lens. This makes theoretical optics concepts easier to visualize during practical demonstrations.
Concave Lens Dia 75 mm FL 20 cm for Ray Diagram Experiments
This lens works effectively in ray diagram analysis and lens combination experiments. Students can examine focal length behavior, image size variation, and virtual image characteristics through hands-on activities. The wide 75 mm diameter allows sufficient light entry, which improves visibility under both natural and artificial lighting conditions.
High-Quality Glass for Accurate Results
The lens uses polished optical glass that reduces distortion and minimizes aberrations. Smooth surfaces ensure clean light paths and consistent experimental outcomes. The material also resists minor scratches and environmental wear, which supports long-term classroom use.
Compatible with Standard Optical Equipment
The concave lens fits easily into common optical benches, holders, and stands. It can be used alongside convex lenses, mirrors, prisms, and light sources to demonstrate combined optical effects. This compatibility makes it a versatile component in teaching geometrical optics.
Durable and Easy to Handle
The robust glass construction provides stability while remaining easy to store and transport. Thermal stability helps maintain optical accuracy under typical laboratory conditions. As a result, the lens performs reliably across repeated demonstrations and student practical sessions.
This product is intended strictly for education and demonstration use only and not for industrial, medical, or commercial optical applications. Overall, the Concave Lens Dia 75 mm FL 20 cm offers precision, clarity, and durability, making it an essential tool for teaching and learning fundamental optics principles.
other educational working models and laboratory kits to enhance hands-on learning in engineering and technical laboratories. In addition, institutions may also explore complementary learning solutions such as Jaadui Pitara educational learning kits to support interactive and concept-based education.
