Review DALLMEYER 25x21 Lens Rare

The Dallmeyer Lens 50214 J.H., measuring a robust 25x21 mm, is a versatile and high-quality optical component designed for various applications. This lens is manufactured by Dallmeyer Optic, a renowned name in the optical industry, known for its commitment to producing superior quality optics.

The Dallmeyer 50214 J.H. is a plano-convex lens, with one flat surface and one curved surface. The convex surface has a focal length of 25 mm, meaning it focuses light to a point 25 mm away from the lens. The flat surface, on the other hand, maintains the image flat, making it ideal for use in applications where maintaining the image plane is crucial.

This lens is made of high-quality BK7 glass, known for its excellent optical properties. BK7 glass has a refractive index of 1.52, a relatively high transmission in the visible spectrum, and a low dispersion, ensuring that colors are not distorted when passing through the lens.

The Dallmeyer Lens 50214 J.H. is coated with a multi-layer anti-reflection coating. This coating reduces reflections and increases the transmittance of the lens, allowing more light to pass through and improving the overall image quality.

The lens has a diameter of 21 mm and a thickness of 8 mm, making it a medium-sized lens suitable for various applications. Its black edge ensures a professional and clean appearance when used in applications that require visual aesthetics.

In conclusion, the Dallmeyer Lens 50214 J.H. is a high-quality, versatile, and reliable optical component. Its large aperture, low dispersion, and multi-layer anti-reflection coating make it ideal for applications in imaging, optometry, and scientific research. Whether you're a professional photographer, an optical engineer, or a hobbyist, this lens is an excellent addition to your collection.
