Lenses

These Lenses listed here are a single lens polished to a spherical shape different to multi-element lens for cameras or telescopes.
The performance is reduced to minimum with a wide range of applications at low cost.

Plano Convex Lenses

Simple shape lenses for laser experiment with a little reduced spherical aberration.
These are available for imaging experiment using a monochromatic light source or using as focusing a laser beam on the detector.

Plano Concave Lenses

Simple shape lenses for spreading the collimated laser beam. These are available for expanding the beam diameter or in combination with convex, expanding the irradiation area of illumination light.

Biconvex Lenses

With its both convex surfaces the biconvex lens refracts light efficiently in a small space, more light is focused.
The particular feature of biconvex Lens is that it enables to focus light at a short distance and also enable it to focus dispersed. Li

Biconcave Lenses

With its two concaves surface, the biconcave lens refracts light efficiently in a small space and spread widely the light.
Possible to use it for enlarging the illumination area.

Reasonable Lenses

It is the product that was reduced by one rank from the surface quality of Plano Convex Lens (SLB-P).

Cylindrical Lenses

Cylindrical plano-convex lens has a convex curvature in the vertical direction and has no curvature in the horizontal direction.
It is used to make experimental and condensing a laser beam in a thin line, a wide light sheet used in the measurement, such as fluid.
