• Cylindrical plano-convex lenses (cylindrical plano-convex lenses) have the curvature of a convex lens in the vertical direction and no curvature in the horizontal direction.
• It is used to produce a wide sheet of light used in experiments where laser light is condensed into thin lines and fluid measurements.
• A lens made by BK7 for the visible to near-infrared range.
• Three types of lenses with anti-reflection films are also available in the visible, near-infrared and infrared ranges.
• By using a cylindrical lens in the optical system, the beam shape and the aspect ratio of the illumination light can be deformed.
• A cylindrical lens holder (CHA) is available for fixing cylindrical lenses.
• * Cylindrical plano-convex lenses have chromatic aberration, and the focal length depends on the wavelength.
• Cylindrical plano-convex lenses allow light to enter in certain directions.
• * Be sure to allow parallel light to enter from the convex side.
• Doing so can cause spherical aberration to increase, which in turn can cause condensation lines to become thicker.
• * The transmittance of the uncoated product is about 90% due to the loss caused by the reflection of the front and back of the lens.
