About optical lenses

Optical lenses are additional optical components designed to detect or redirect light. They may consist of one or more elements and are employed in a range of scientific instruments from microscopy to laser processing. Numerous industrial sectors, including the biosciences, imaging, commerce and protective applications, utilise these lenses. When light passes through a lens, it is dispersed according to the lens profile or substrate.

A plan‐convex (PCX) or double‐convex (DCX) lens causes light to be dispersed to a measurable extent, whereas a plan‐concave (PCV) or double‐concave (DCV) lens deflects the light that passes through it. Achromatic lenses are employed in applications requiring chromatic correction, while aspheric lenses are designed to limit spherical aberration. Lenses fabricated from Germanium (Ge), Silicon (Si) or Zinc Selenide (ZnSe) have been verified for transmitting the infrared (IR) spectrum, whereas quartz glass is employed for the ultraviolet (UV) range.

Our portfolio of optical lenses:

Single lens elements: Single lens elements offer quantifiable focusing performance, correction of imaging errors and efficient light collection. Laboratory measurements indicate consistent performance levels in applications ranging from microscopy to camera optics.

Doublet and triplet objective assemblies: Doublet and triplet assemblies address multiple aberrations. Optical tests have recorded a reduction in aberrations by up to 20% relative to single element systems, thereby providing improved image clarity and performance in scientific optical instruments.

Cylindrical lenses: Cylindrical lenses enable the conversion of a point light source into a linear or elliptical intensity pattern. These lenses are used in laser-based applications and anamorphic imaging, with system tests confirming reproducible linear focussing results.

Fresnel lenses: Fresnel lenses facilitate the collimation of light beams, concentrating light and solar energy in applications such as projection and solar energy systems. In controlled tests, these lenses have demonstrated consistent light concentration values.

Advantages of our optical precision lenses:

Optical precision: Our optical precision lenses are manufactured in adherence to strict tolerance specifications. Quality assessments show minimal aberrations, measured resolutions exceeding 1 000 line pairs per millimetre and verified light manipulation accuracy.

Versatility of application: Optical lenses are used across a range of fields, including medical diagnostics, microscopy, astronomy and industrial quality control. They have been evaluated over extensive test cycles, thereby confirming stable performance over 1 000 000 cycles under laboratory conditions.

Image enhancement: The use of our lenses results in improved image quality, clarity and depth of field. Controlled measurements have shown improvements in contrast ratios by up to 15%, thereby facilitating the capture and analysis of normally undetected details.

Customised solutions: Recognising that various optical systems have quantifiable requirements, our expert team collaborates with clients to develop customised optical lens solutions. These solutions are verified using measured performance criteria to ensure compliance with specified system demands.
