About This Product

Turning parallel rays into diffused rays, it looks just like a diffused ray emanating from a point ray at the focal point of a lens. They can be incorporated into optical systems to help extend the focal length, or simply used to diffuse light.

As a general rule, the concave side of a plano-convex lens faces the direction in which parallel or approximately parallel light rays come. The choice of plano-concave or biconcave is determined by the residual aberration of the optical system.

■Basic propertiesWhen light enters a transparent material such as glass, it is refracted, and when it exits it, it is also refracted. If you use rotationally symmetrical glass and make it tilted so that it refracts inward as it moves away from the axis (thicker in the center than at the edges), it is possible to collect light, which is called a convex lens.

For a single lens, its axis of rotational symmetry is called the optical axis. In the following, it is assumed that the speed of light incident on the lens passes through a sufficiently narrow region near the optical axis (paraxial approximation holds). Light rays parallel to the optical axis converge at a single point after passing through a convex lens. This point is called the focal point.

The leg of the perpendicular line drawn down on the optical axis from the point where the ray before entering the lens and the ray exiting the lens and passing through the focal point intersect is called the principal point. The distance from the principal point to the focal point is called the focal length. There are two focal points depending on whether the parallel light enters the lens from the front or back, and there are also two principal points.

There are two focal points depending on which side you enter from, and there are also two principal points. However, the focal length is the same for both front and rear. Also, if we assume that the lens thickness is negligibly thin (thin lens approximation), the two principal points coincide.

■Convex lenses mainly have the following properties.・Light rays parallel to the optical axis pass through the convex lens and then through the focal point
・Light rays emerging from the focal point pass through a convex lens and become parallel to the optical axis.
・Light passing through the nodes of the lens travels without changing its angle.

■Synthetic quartzSynthetic quartz is an optical glass material for transmission, but because it has a much lower expansion than materials such as BK7, it is used as a high-precision substrate for various optical products.

■Features・The transmittance in the visible and ultraviolet regions is the highest among optical glasses, and there are few bubbles and impurities.
・Low thermal expansion, wide usable temperature range (maximum temperature around 800℃)
・Low fluorescence even under strong ultraviolet light.
・The material is harder than other materials and is less prone to scratches.
