Convex Lens BK7 Optical Glass Cylindrical Plano Convex Lens For Optical Instruments
In the field of high-precision optics, the Convex Lens BK7 Optical Glass series is recognized as a fundamental component for advanced light manipulation. Specifically, the Cylindrical Plano Convex Lens is designed to focus light into a sharp, uniform line rather than a single point, making it an essential optic for various scanning and alignment systems.
By utilizing premium BK7 Optical Glass, these lenses offer high homogeneity and low bubble content, ensuring maximum transmittance across the visible spectrum. The unique geometry of the Cylindrical Plano Convex Lens—featuring one flat surface and one cylindrical curved surface—allows for the compression of light in only one dimension. This capability is critical for optical instruments that require beam shaping, such as laser levels, barcode scanners, and high-resolution imaging devices.
