Lens

A lens manipulates light through refraction, either concentrating or dispersing it. Unlike a prism that refracts without focusing, a lens concentrates light to create an image. Typically crafted from glass or plastic, lenses can also be fashioned from liquids, mimicking the focusing mechanism of the human eye. Glass lenses are meticulously shaped through grinding and polishing. In contrast, plastic lenses are formed through molding.

Simple lenses are categorized into eight types based on the curvature of their two optical surfaces.

 

Converging Lenses

  • Convex Lens
  • Biconvex lens
  • Plano-convex lens
  • Positive meniscus

Diverging Lenses

  1. Concave lens
  2. Biconcave lens
  3. Plano-concave lens
  4. Negative meniscus

Achromatic Lens: Achromatic lenses offer exceptional off-axis performance and are engineered to maintain a consistent focal length irrespective of aperture and operating wavelength. Typically produced as doublets or triplets, they provide superior color correction within the visible wavelength range. Their application is prominent in fields demanding precise analytical observation, such as microscopes and medical instruments.


Spherical Lens: A spherical lens features a curved surface with a spherical shape. Initially categorized as convex or concave, it is further divided into Plano, double, and meniscus lenses within these groups.

 

Aspherical Lens: Unlike spherical lenses, the aspherical lens utilizes a non-spherical curved surface. Its design aims to minimize spherical aberration, reducing the need for multiple lenses while achieving a focused, distortion-free image.

 

Cylindrical Lens: This lens selectively focuses or magnifies light along a single axis, making it ideal for one-dimensional light manipulation applications. Cylindrical lenses commonly used in optical metrology, laser scanning, and various optical processor applications use materials such as N-BK7 glass, UV fused silica, or CaF2.

Prism

Prisms serve various optical functions—reflective prisms redirect light, dispersive prisms spread light, and beam splitters divide light. They are typically crafted from glass, although any transparent material suitable for the intended wavelength can be utilized, including plastic and fluorite.
Prisms are meticulously designed with varying surface angles tailored to specific applications. ILLUCO specializes in producing high-precision prisms, leveraging two decades of accumulated expertise and technological prowess.


Balsam, particularly Canada balsam, is a resin sourced from the Canadian balsam tree. With its pale yellow transparency and high viscosity, it is prized for its optical quality and a refractive index akin to crown glass.
This resin is commonly employed as an adhesive in lens and microscope slide production. In prism construction, it serves as the bonding agent for diagonally cut calcite in Nicole Prisms, which is essential for generating and analyzing planar polarization.

Filter

An optical filter selectively allows light within specific wavelength ranges—colors—to pass through while absorbing the remaining wavelengths. Typically, these filters either permit the transmission of solely longer (longpass filter) or shorter wavelengths (shortpass filter), or they block both extremes, creating a band within a specific wavelength range (bandpass filter).
They find utility in various applications such as cameras, diverse optical instruments, color stage illumination, and even astronomy, where they restrict transmitted light to a particular spectral band of interest. Optical filters are critical in fluorescence-related practices like microscopy and spectroscopy.
ILLUCO boasts diverse filters, encompassing simple color glass filters to highly specialized narrow bandpass filters featuring robust coatings.

Coating

Optical Coating

Optical coatings play a pivotal role in enhancing the performance of optical components. They reflect, guide, or filter light, minimize unwanted reflections, and safeguard the lens surfaces.
At ILLUCO, an array of coatings is crafted, ranging from fundamental anti-reflection coatings, which diminish surface reflections commonly found in glasses and photographic lenses, to sophisticated high reflector coatings that enable mirrors to reflect over 99% of incident light. Additionally, more intricate optical coatings, like dichroic thin films, exhibit high reflectivity within specific wavelength ranges while ensuring anti-reflection in others.

Design

Optical lens design involves tailoring a lens to meet specific performance criteria while considering various limitations, encompassing cost and manufacturing constraints.
This intricate process involves defining parameters such as surface radius, distance between surfaces, material selection, and nuanced adjustments like selective tilt and center removal. It also involves determining the type of surface profile—spherical, aspherical, holographic, diffractive, and others. The computational intensity of this process lies in modeling how light interacts as it passes through the lens, demanding technical expertise and a wealth of experience.
ILLUCO excels in the professional design of optical components. Leveraging our expertise, we analyze customer requirements to offer the most efficient and optimized solutions.
