41 Microlens Arrays, Introduction Microlenses for fiber coupling and optical switching Microlenses for collimation of laser diodes and VCSELs Microlenses for imaging systems and sensors Beam homogenizers for lasers and illumination systems Array optics featuring high precision For the best imaging characteristics (aspherical lenses) Simplified alignment and assembly (planar substrates) Refractive microlenses are the No. 1 choice for all applications in which miniaturization of an optical system and reduction of alignment and packaging costs play a major role. Microlenses typically have a lens diameter of 10 µm to 2 mm and are produced in the form of arrays (fields) on planar substrates (wafers). Refractive microlenses are manufactured from synthetic fused silica or silicon in a cleanroom environment using the highly sophisticated processes of the semiconductor industry (photolithography, plasma etching). These processes allow precise production of complex array optics and excellent optical quality of the microlenses. Specifications of microlenses Refractive microlenses are characterized by the lens diameter D and the focal length ƒ. SAG radius of curvature lens diameter substrate thickness focal length object distance image distance Additional parameters are the sag at the lens vertex SAG, the refractive index n 1, the radius of curvature ROC, the conic constant k and the numerical aperture NA. 378 Phone numbers: US UK Singapore

42 For spherical lens profiles, the conic constant k is 0; for parabolic profiles, k = -1 and for hyperbolic profiles, k = -(n 1 ) 2. High-grade microlenses are usually made of synthetic fused silica (refractive index n 589nm = 1.458) or silicon (n 1.5µm = 3.478). Fused silica microlenses can be used in the full wavelength spectra from DUV to IR (see transmission curve); silicon microlenses are designed for the infrared wavelength range (λ: 1.2 µm to 15 µm). 2 Applications Typical tasks of microlenses in an optical system are collimation and focusing of light beams, or imaging an object in a focal plane. In optical communication engineering, a microlens array is used to image the light of a fiber bundle onto an array of micromirrors. A second microlens array couples the deflected light of the individual data channels back into a fiber array. The high precision of the lateral array dimensions (better than ±0.25 µm) allows a very accurate fiber-to-lens positioning of many channels in one alignment step. The high-class lens quality and the exceptional lens-to-lens uniformity ensure optimal coupling efficiencies for all optical channels in parallel. Aspherical lens profiles are used to minimize the spherical aberrations for different optical configurations (vertical incident light). a) Lens on object side working distance b) Lens on image side working distance The small pupil diameter of microlenses requires careful design of optimal systems, taking into consideration diffraction effects, light scatter and mechanical tolerances.

47 Varioptic Autofocus Liquid Lens Operating mode of liquid lenses The liquid lenses developed by VARIOP- TIC are based on the phenomenon of elec tro-wetting. A water drop lies on a metallic substrate, which is covered by a thin insulation layer. The voltage applied between substrate and water drop varies the contact angle between water drop and substrate. Liquid lenses from VARIOPTIC use two liquids, one of which is used as an insulator, while the other one is used as conducting layer. Varying the applied voltage leads to a change in bend of the border layer between both liquids. This causes a change in focal length of the lens. VARIOPTIC owns two fundamental, worldwide patents about this technology and is dedicating a large part of their development capacity to the improvement and expansion of these patents. Characteristics of liquid lenses: Large range of focal length Robust no moving components Short reaction time Very good optical quality Good transmission in the range of visible wavelengths Large range of operating temperature Very good stability of the optical axis Low power consumption Simple, cost-saving design Medical technology The big potential of VARIOPTIC with refer ence to miniaturisation creates many new opportunities in the area of imaging. So, liquid lenses are, for instance, suitable for installation inside endoscopes, confocal microscopes and for laser focusing. Oph thalmology will also benefit from this new technology of liquid lenses. Biometry and identification The short reaction time of 2/100 s is an essential benefit for recognising specific features: barcodes or biometric character istics like iris or finger prints. The manufacturer: VARIOPTIC is a leading enterprise in development and manufacturing of electronically controlled liquid optical lenses for the optical industry. VARIOPTIC is, for instance, the first enterprise which was granted international patents for a single-component focusing lens, which is based on non-mixable liquids. In order to retain and to further develop their technological head start, VARIOPTIC invests increasingly in research and development. VARIOPTIC has its headquarter in Lyon, in France, and was founded in Field of application: For future mobiles, PDAs, etc. According to the technology used, VARIOPTIC s optically controlled lenses are also called liquid lenses. Liquid lenses are well-suited for the next generation of mobile devices with camera function: mobiles, PDAs, digicams and many more. The VARIOPTIC-technology offers some key benefits for this type of devices: Very small size: 8 mm in diameter, thickness of 2 mm Simple design Short reaction time < 2/100 s Low power consumption 384 Phone numbers: US UK Singapore

51 Focus-Variable Lenses from Optotune The focus-variable lenses from Optotune are manufactured from elastic polymers and have unique properties: the lens shape can be changed from convex to concave mechanically or electronically. A clear aperture from 1 to is 30 mm is possible. Both lens types work with the same principle: two chambers are separated through a thin mem-brane, one chamber is filled with a liquid and the other with air. The pressure difference between the two chambers defines the deflection and with that the radius of the lens. The pressure difference is being controlled by using a thread ring to push a ring-shaped actuator down onto the chamber. The changes are reversible; there is no hysteresis. a: lens radius w0: central bending (depends on current) h: constant zone of the lense material = 1.57 ± 0.1 mm (EL-10-30) d: thickness of the cover glass (BK7) = 0.5 mm t: overall thickness of the lense = 7.57 mm ± 0.1 mm (EL-10-30) red: fixing of the membrane yellow: adaptive lens material (Optotune) Optical design of the electric focus-variable Lense EL High Quality Advantages of focus-variable lenses fromoptotune: Compact design Fast response time Robustness (no complex mechanics) High switching frequency (frictionless) 388 Phone numbers: US UK Singapore

52 Advantages Field of Application Fast Autofocus The variable focal length of these innovative spherical lenses enables the design of very compact optical systems. A change in the radius of curvature of just a few micrometers can correspond to an axial shift in the centimeter range. The typical switching frequency of the electronically adjustable lens is of the order of about 100 Hz. Fewer lenses will be needed for an optical design; an axial movement of the components is less complex or even unnecessary. No need for complex mechanics or motors anymore. This means: fewer moving components and thus a lighter, more rugged, fully closed and dust-free design. These lenses are ideally suited to be used both in compact imaging systems and in illumination systems, such as LED-based systems. Compact Zoom Optic A change of the radius of curvature of a lens has a greater visual effect than is common practice with adjusting lenses. This enables the development of more compact optical systems. This way it is possible to save up to 50% of the overall length of e.g. an optical 3-times zoom lens. Applications in the Machine Vision field often demand very fast focusing onto different working distances. This most often requires that the radius of one single lens is being adjusted which is the ideal application area of the focus-variable lens.

53 Electrically Focus Variable Lens EL Compact optics and short setting time: EL allows for that due to its electrically tunable focal range. Within 10 ms, the radius of this plano-convex lens can be changed by applying a voltage between 0 and 5 V. The lens can be operated with commercial power supplies allowing for current control. Power consumption is less than 2 W. For each lens a test chart displaying the dependendency between focal length and current can be provided. In the download area, a DLL is provided for embedding the lens in ZEMAX.

The radius of this spherical lens with an aperture of 20 mm can be changed manually by turning a ring. The focal length can be changed from plano-concave via infinity (plane) to plano-convex. This lens is very convenient for educa tion purposes or prototyping.
