EL-10-30-C

EL-3-10

Design faster and more compact optical systems without complex mechanics using the electrically focus tunable lens EL-10-30-TC. By applying a current, the focal length of the 10 mm aperture lens can be tuned to a specific value in milliseconds. Thanks to an integrated temperature sensor and characterization data, the lens can be driven to precise focal powers using Optotune's lens driver 4. The EL-10-30-TC is available with two broadband coating options, VIS for 400-700nm and NIR for 700-1100nm.

Design faster and more compact optical systems without complex mechanics using the electrically focus tunable lens EL-10-30-C. By applying a current of 0 to 300mA, the focal length of the 10 mm aperture lens can be tuned to a specific value within milliseconds. The EL-10-30-C also features threads on either side for easy mounting as well as the possibility to replace the cover glass with a fixed focus offset lens, allowing for free adjustment of the focal length range according to the requirements of your application.

EL-16-40-TC

With a clear aperture of 16 mm Optotune presents the worlds‘s largest electrically focus tunable lens. Its design has been optimized in many ways:

• The 60% larger aperture than its predecessor, the EL-10-30, allows for 2.5x more light throughput

• The tunable lens can be shaped from a flat zero-state into a  plano-concave or plano-convex lens, resulting in a focal tuning range of  up to -10 to +10 diopters (at -250 to +250mA)

• The design was optimized to minimize thermal drift effects to as  little as 0.02 dpt/°C and with the built in temperature sensor, an  overall reproducibility of typically +/- 0.05 diopters is achievable

• Response & settling times are 5 & 25ms, respectively, which is still magnitudes faster than most mechanical alternatives

• Integration of the lens shaper inside the container allows for the highest possible positioning accuracy of the tunable lens

The compact EL-3-10 lens was designed for OEM integration into optical systems for various applications. The working principle is based on the well-established shape-changing lens technology. The curvature of the lens is adjusted by applying an electrical current. Thereby, the focal length is tuned to a desired value within very few milliseconds. The lens architecture is “push pull” which means that the lens curvature is deflected from concave to convex. With actuators based on proven voice-coil technology, the EL-3-10 focus tunable lens is extremely reliable and robust, well suited even for applications in harsh environments over large temperature ranges.

EL-10-42-OF

The electrically focus-tunable lens EL-10-42-OF with integrated proprietary OF (optical feedback mechanism) is dedicated to 3D laser processing applications and sets the highest standards in terms of spot quality and speed. With a focus tuning range of -2.0 to +2.0 diopters the spot can be controlled over a large range along the z-axis (working distance change of up to 180mm) with a long term repeatability of <0,02 dpt. The EL-10-42-OF is optimized for the use at 1064nm and 532nm up to 50W.

TRANSMISSIVE LSP-3010

TRANSMISSIVE LSR-5-17

TRANSMISSIVE LSR-3005

The LSR-3010 is designed for practical use on your optics table and integrates certified drive electronics powered through a single micro-USB connector (5VDC). Two standard diffuser configurations are available: 6°  for highest optical efficiency and 12° for best speckle reduction. Both models combine an oscillating diffuser with a static diffuser to reduce the correlation length of the random patterns that are generated. This provides more effective speckle reduction yet minimizing the increase in beam divergence.

The OEM version of Optotune's laser speckle reducer comes with a minimal housing and is available with or without drive electronics.

The most important parameter is the choice of diffuser angles. Standard diffuser angles of 1°, 4.3°, 8.5° and 17° are available. The LSR consists of a dynamic diffuser and optionally a subsequent static diffuser. The latter is recommended when no homogenizing optics follow the LSR to increase the speckle reduction factor. Finding an appropriate system layout is key to effective and efficient speckle reduction. Our application note contains several suggestions, suitable for a variety of applications.

TRANSMISSIVE LSR-10-22

Optotune’s standard diffusers are made of a proprietary polymer, which offers a transmission range of 240 to 2500nm at a typical transmission of 93% and damage threshold of 300W/cm2. The diffuser itself is not coated, however VIS and NIR coated cover glasses are available as a standard. It is also possible to work with glass diffusers if they are similar in size and weight.

With an oscillation frequency of 180 Hz and an amplitude of about 400um, the 10mm aperture model is the preferred choice for applications with frame rates below 180Hz or for the human eye.

The  LSR-3005 is designed for practical use on your optics table and  integrates certified drive electronics powered through a single  micro-USB connector (5VDC). Four standard diffuser configurations are  available ranging from 6° (highest optical efficiency) to 24° (best  speckle reduction). Most models combine an oscillating diffuser with a  static diffuser to reduce the correlation length of the random patterns  that are generated. This provides more effective speckle reduction yet  minimizing the increase in beam divergence. The 17° model, which  consists of a dynamic diffuser only, is particularly suitable when the  diffuser needs to be in the image plane as is the case e.g. with  holographic LCOS or in fiber coupling setups.

LSR-4C-L

Optotune’s LSR-4C-L speckle reducer has an aperture of 18.5x18.5 mm and is especially suitable for applications where high laser powers and large beam diameters are used. The diffusor is mounted in a thin steel frame. As part of a larger metallic structure the frame is set into motion by the reluctance force, generated by the oscillating magnetic field of a driving coil. If required, the LSR-4C can combine two oscillating diffusors rotated by 90°, realizing optimized despeckling in both directions. The compact driving electronics, assembled on a flexible plastic substrate, stabilizes the resonance frequency in closed-loop mode and includes an error signal.

MR-10-30

MR-E-2

MR-15-30

Optotune’s one-axis-resonant dual axis voice coil mirror series MR-10-30 is the ideal choice for applications that require fast scanning and large deflection angles in a compact form factor. With a mirror size of 10 mm the MR-10-30 achieves up to ± 25° mechanical tilt in the linear axis and up to ±12.5° mechanical tilt in the resonant axis, resulting in a 100° x 50° field of view.

The MR-E-2 driver is an ideal solution for driving the MR-series 2D beam steering mirrors. It consists of a base unit containing control electronics and an integrated head unit with mirror and driving electronics. The driver in the standard version with housings can be used for testing and proof of concept work. The boards without housing are available as OEM version for integration with system electronics.

TP-12-16

The tunable prism is a tunable wedge that allows to tilt two optically  flat and AR coated glass windows with respect to each other. The two  glass windows are held together by a bellow structure that is filled  with a low dispersion clear optical fluid. The core element can be  integrated with a large variety of actuation principles such as  mechanical or motorized lead screws, voice-coil and piezo actuators.

Optotune’s dual axis voice-coil mirror (VCM) series MR-15-30 is the ideal choice for applications that require large deflections in a compact form factor. With a mirror size of 15mm the MR-15-30 achieves up to +/- 25° mechanical tilt, which results in up to +/- 50° optical deflection. The mirror includes a position feedback system which allows it to be accurately controlled with a standard PID controller.
