[Features]
· With a simple shape, this is a lens for use in laser experiments with somewhat reduced spherical aberration.
· Can be used for condensing laser light in detectors, conducting imaging experiments with monochromatic light sources, etc..
· A BK7 lens for the visible range to the near infrared range.
· Three types of lenses with antireflection coating in the visible range, near-infrared range, and infrared range are available.
· Selection can be made from a wide range of variations subdivided by outer diameter, focal distance, and so on, to suit the specifications.
· Achromatic lens (DLB) subjected to chromatic aberration correction is also available.
· * Spherical surface planoconvex lenses have chromatic aberration, resulting in focal lengths changing with wavelength.
· * The planoconvex lens has an orientation for light incidence.
· * Be sure to have parallel light incident from the convex surface.
· * When reversed, spherical aberration may increase and the condensing spot may widen or images may be out of focus.
· * Non-coated products have loss due to reflections at the front and rear surfaces, with a transmittance of about 90%.
