Product Description
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.

Expert Product FAQ: Mastering Optical Instruments with BK7
This section provides authoritative technical insights into the selection of the Convex Lens BK7 Optical Glass and Cylindrical Plano Convex Lens.
Q1: What is the main function of a Cylindrical Plano Convex Lens compared to a spherical lens?
Answer: A spherical lens focuses light into a point. In contrast, a Cylindrical Plano Convex Lens focuses light into a line. This is essential for optical instruments that need to project a "light sheet" or a scanning line across a surface.
Q2: Why is BK7 Optical Glass the industry standard for these lenses?
Answer: BK7 Optical Glass is a high-quality crown glass that is extremely hard and resistant to chemical stains. For a Convex Lens BK7 Optical Glass component, this ensures the Cylindrical Plano Convex Lens remains durable and clear even in rugged field-based optical instruments.
Q3: Can I get a Cylindrical Plano Convex Lens with a custom coating?
Answer: Yes. To maximize the efficiency of your Convex Lens BK7 Optical Glass, we can apply Broadband Anti-Reflective (BBAR) coatings. This reduces light loss at the Cylindrical Plano Convex Lens surfaces, which is critical for low-power optical instruments.
Q4: How does the size of the lens affect its performance in Optical Instruments?
Answer: The size determines the light-gathering power. Our Convex Lens BK7 Optical Glass manufacturing covers micro-optics up to large-scale lenses, ensuring the Cylindrical Plano Convex Lens matches the aperture of your specific optical instruments.
Q5: What is the typical surface quality required for a professional Cylindrical Plano Convex Lens?
Answer: Most high-end optical instruments require a surface quality of at least 40-20. Our Convex Lens BK7 Optical Glass process often achieves 20-10, providing a pristine finish that minimizes beam deviation in the Cylindrical Plano Convex Lens.
