Spherical Plano-Convex Lens BK7 Type SLB Series

[Features]
·It is a lens with a simple shape and slightly suppressed spherical aberration for laser experiments.
·It can be used for focusing laser light on a detector, for imaging experiments using a monochromatic light source, etc.
·It is a lens made by BK7 for the visible range to the near infrared range.
·There are 3 types of lenses with anti-reflection film: for visible range, near-infrared range, and infrared range.
·You can choose from a wide variety of subdivided outer diameter sizes and focal lengths according to your specifications.
·Chromatic aberration-corrected achromatic lenses (DLB) are also available.
· * Spherical plano-convex lenses have chromatic aberration, and the focal length changes depending on the wavelength.
· * The plano-convex lens has a certain direction to let in light.
· * Be sure to inject parallel ray from the convex side.
· * If the light is injected from the opposite side, the focused spot may become large and the image may appear blurred, as the spherical aberration becomes large.
· * The uncoated product has a transmittance of approx. 90% due to the loss caused by reflection on the front and back surfaces of the lens.
