What Makes Apochromatic Lenses Important?Because apochromatic lenses focus colors at the same point, they allow users to fully focalize the image. Compared with uncorrected singlet lenses, apochromatic lenses can produce clearer images, maki...view
Pentagonal Prism/Half Pentagonal Prism EstimateThe pentaprism deviates the lights beam by 90° through reflection of two surfaces while maintaining image parity. The deviation of the beam will not change the slight rotation of the prism, so it is ...view
Achromatic Lenses1. The introduction of achromatic lensAchromatic lenses have various configurations, the most common of which are positive achromatic lenses, negative achromatic lenses, three-phase achromatic lenses ...view
The Application of Zoom LensesⅠ. The selection principle of the zoom lensesThe maximum imaging circle size of the lens should not be less than the imaging specification of the camera chip, that is to say, 1/2 lens can be used wit...view
What Is a Beam Expander?1. Brief introduction of beam expanderA light or laser beam expander is a scientific instrument that can expand the input beam of parallel light or laser into a larger output beam. In terms of usage, ...view
Types and Applications of Optical Prisms1. What are optical prisms?In optical devices, optical prisms can cut a piece of glass or other transparent materials at a precise angle and plane, which can be used to analyze and reflect light. Ordi...view
