Lens manufacturing capabilities

  Spherical lenses

    Manufacturing

Spherical lenses can be manufactured per different processes:

– Moulded and polished (for big quantities)
– Mechanical grinding and polishing
– NC grinding and polishing (high surface request lenses)

Different shape can be provided:

– Plano-convex lenses
– Plano-concave lenses
– Bi-convex lenses
– Bi-concave lenses

   Specifications

SINOPTIX offers most of the optical glass available on the market:

– B270
– N-KB7 / HK9L
– SCHOTT / CDGM / CORNING / OHARA optical glasses
– Fused Silica (JGS1 / JGS2 / JGS3)
– Borosilicate
– Zerodur®
– IR materials : Ge / Si / CaF2 / MgF2 / BaF2 / ZnSe / ZnS

Lens quality depends on their size, material and complexity. Below some specifications that can be achieved just for references:

Size up to Diam 350mm
Transmission high transmission from UV to far infrared
Scratch & Dig 10-5
Surface irregularity λ/10
Dimensional tolerances up to +/- 0,01mm
Clear Aperture 90 to 95%
Centering better than 3 arcmin
Coatings Custom coatings available on request

   Lens quality control

To ensure the quality of our lens before expedition a 100% inspection is made by SINOPTIX own QC. Control may include:

– Aspect (scratch & dig)
– Dimensions
– Radius of curvature
– Surface quality (interferometer)
– Transmission
– Focal length measurement

  Doublet / Achromatic lens

Doublets are made of two lenses of different refraction index cemented together with the purpose to compensate the chromatic aberration in order to have an achromatic final component (different wavelength signals will have the same focal length).

Doublets have better optical characteristics than single lens therefore they are widely used in the imaging industries and applications where a stable focal length is requested.

  Aspherical lens

Aspherical lenses, widely called “Aspheres” are conic shaped lenses (in opposition of spherical ones) , with specific shape that compensate the spherical aberration.

Aspheres shapes are defined by a conical equation as below:

formula

  Z stands for the surface (SAG) of the lens
  R is the Radius of curvature
  K: Conic constant
  Ax: Aspherical coefficient of xth order (can be null)

Aspherical shape is more difficult to manufacture than spherical ones, that is why molded asphere parts are preferred to CNC machined ones. Molded aspheres requires quantities in order to compensate for the high mold costs. Small quantities request are also possible but are relatively very expensive compare to spherical lenses.

Aspherical is an alternative to a complex system of several spherical lens, providing simpler and smaller systems.

  Cylindric lens

Cylindrical lenses have a constant curvature radius on their whole length. They are mainly used in applications in one dimension, like focusing light not only on a point but on a band.
AR and other surface treatments may be provided.

  Toric lens

Toric lens can be imagined as a cut in torus (“doughnut” shape) which implies two different radius of curvature in two perpendicular directions. This specific shape, widely used in ophthalmic optics, enable to have a different optical power in two directions of the same length.

Toric lens are also called Toroidal lenses or Toroid lenses.
