  Fresnel Lens

  NTKJ

  Fresnel lenses are a type of lens that has only the curvature flattened to a plane.　Fresnel lenses, though plane, can act as spherical lenses. Since they are essentially flat, Fresnel lenses offer tremendous space- and weight-saving, and also enable focal lengths shorter than their aperture, a feat impossible with spherical lenses.
  They are widely used as field lenses for cameras, condenser lenses in overhead projectors, rear projector screens, for optimal gathering of solar energy, lenses in LED lighting, in optical sensors, etc.

  B Type Fresnel Lens

  NTKJ

  Fresnel lenses are a type of lens that has only the curvature flattened to a plane.　Fresnel lenses, though plane, can act as spherical lenses. Since they are essentially flat, Fresnel lenses offer tremendous space- and weight-saving, and also enable focal lengths shorter than their aperture, a feat impossible with spherical lenses.
  These Fresnel lenses are designed with the plano side facing the parallel light source. They are used as a light concentrator in solar photovoltaic generation systems, focusing sunlight on high-density solar cell elements to consolidate the solar energy. These lenses are also used in solar furnaces for processing materials at high temperatures.
  Because they were designed to condense parallel light, condensing Fresnel lenses with short focal distances can be combined with a sensor, etc. for light-detecting applications.

  Sharp Cut Filter (for visible region)

  SURUGA SEIKI

  [Features]
  · There are four types of color filters available for light from the ultraviolet to infrared regions: sharp cut filters (absorbs light from wavelengths shorter than the given wavelength and transmits light with longer wavelengths), heat ray absorption filters, ultraviolet-bandpass visible-absorption filters, and blue filters.

  Prism

  NTKJ

  Prisms are arranged on a flat surface with their angles aligned. They are used to bend incident light in specified directions.　Prisms are commonly used in LCD panel backlight modules, etc. as light entering from one face can be emitted from the surface.

  Prism, Right Angle (With Coating) S21

  SURUGA SEIKI

  [Features]
  · A right angle prism is used for bending light 90° or 180°.
  · The function is the same as a mirror, but by using a prism for the reflective function, in general, systems can be made more compact. Also, since the mirrored surface features a protective coating, degradation of the imaging performance due to dust and scratches is minimized.
  · Caution is needed when using for white light, since chromatic aberration may occur due to the dispersion properties of the material (wavelength dependence of the refractive index).
  · Divided into B and C types depending on the difference in the coating applied to each surface of the prism.

  SURUGA SEIKI

  [Features]
  · Light is bent 90° using the total reflection of the sloped surface.
  · Can be used as a substrate for making a variety of optical elements.
  · The BK7 can be used for regions from the visible region to the infrared region. Synthetic quartz can be used for regions from the ultraviolet region to the infrared region.

  Mirror, Dielectric Total Reflection

  SURUGA SEIKI

  [Features]
  · A dielectric multi-layered total reflection mirror in which films with different refractive indexes have been vacuum deposited on an optically polished glass substrate.
  · A high reflectance of 99% or greater can be obtained since there is no absorption by the film (compared with metal film reflection mirrors, such as aluminum types).
  · A high level of reflection is achieved regardless of the polarization state of the entered light, but it does depend on the wavelength and angle.
