Announcement of Import and Sales Start for Next-Generation Active Optical Components, Including Optotune's Focus Tunable Lenses, Used in a Wide Range of Fields Such as Medical Devices, Microscopes, and LiDAR, Achieving High-Speed and High-Precision Focus Control

Kohsoku Co., Ltd. has begun importing and selling focus tunable lens products from Optotune.

Optotune, headquartered in Switzerland, is an optical component manufacturer that develops and manufactures proprietary tunable optical technologies, primarily focus tunable lenses. They also offer next-generation active optical components that contribute to solving optical system challenges, such as the "LSR series" laser speckle reducers that improve laser light quality and steering mirrors that enable high-speed beam control.

Focus tunable lenses are characterized by their ability to achieve high-speed, high-precision focus adjustment and optical scanning, which are difficult with conventional fixed lenses. Since they do not require mechanical lens drive mechanisms, the drive unit can be made compact, and they offer high durability with minimal wear. As a result, they are adopted in a wide range of fields requiring advanced optical control, including medical devices, microscopes, industrial laser processing, machine vision, LiDAR, and AR/VR.

<EL Series>

- EL-3-10

Compact and Ultra-Fast Focus Control

The EL-3-10 is designed for seamless integration into OEM products, even in space-constrained environments. Utilizing Optotune's proprietary shape-changing lens technology and "push-pull" architecture, it achieves switching from concave to convex in less than 1 millisecond. Its robust voice coil actuator ensures reliable performance in harsh environments and across a wide temperature range.

Key Benefits

Ultra-fast response time (<1 ms)

Wide focal length range of 26 diopters

Extremely low power consumption (less than 15 mW for ±5 diopters)

Stable operation for over 1 billion cycles even in harsh environments

Specifications

Product Category: Electrically Controlled Focus Tunable Lens

Aperture Diameter: 3 mm

Outer Dimensions: 10 mm

Focus Adjustment Method: Electrical Control

Response Speed: High Speed Response

Features: Compact and lightweight design, high-speed autofocus compatible

Main Applications: Machine vision, medical devices, microscopes, barcode readers

<ML Series>

- ML-20-37 Seamless Refractive Adjustment from -18 to +18 Diopters The ML-20-37 is a mechanically focus-adjusted lens with an effective aperture of 20 mm and an optical power range of -18 to +18 diopters. Focus is adjusted by rotating the outer ring, smoothly changing the lens curvature from concave to convex. Its durable, low-torque mechanism ensures a long lifespan, and it is easy to drive with a motor, enabling precise and repeatable focus control. The availability of a C-mount adapter option allows for seamless integration into a wide range of optical systems.

Key Benefits

Wide optical power range of 36 dpt

Zero holding power

Extremely high durability (over 100,000 rotations)

Linear low-torque mechanism for smooth adjustment

Easy motor drive with repeatability of approximately 0.1 dpt

Specifications

Product Category: Manually Adjustable Focus Tunable Lens

Aperture Diameter: 20 mm

Outer Dimensions: 37 mm

Focus Adjustment Method: Manual Adjustment

Features: Large aperture support, high optical flexibility, no power required

Main Applications: Research and development, laser optical system adjustment, evaluation purposes

<Laser Speckle Reducer LSR Series>

- LSR-4C Compact Speckle Reduction Optotune's LSR-4C reduces speckle through dynamic diffusion. By rapidly moving a diffuser plate, it averages multiple interference patterns, achieving a uniform, speckle-free beam. With a large effective aperture of 18.5x18.5 mm, it is designed for high-power, large-beam applications such as laser cinema projection. Its metal frame and reluctance actuation ensure reliable operation.

Key Benefits

Large effective aperture of 18.5 x 18.5 mm supports high power and large beam diameters

Compact electronics with closed-loop resonance stabilization

Optional dual 90° diffuser configuration for optimized bidirectional speckle reduction

Integrated error signal for system monitoring

Specifications

Product Category: Laser Speckle Reducer

Aperture Diameter: 4 mm

Operating Method: High-speed vibration type

Features: Speckle noise reduction, compact design, low power consumption

Main Applications: Laser projectors, microscopes, machine vision

- LSR-5 Compact Speckle Reduction Optotune's LSR-5 reduces speckle through dynamic diffusion. By rapidly moving a diffuser plate, it averages multiple interference patterns, achieving a uniform, speckle-free beam. With an effective aperture of 5x5 mm, the LSR-5 is a cost-effective alternative to the LSR-4C for applications that do not require a very large effective aperture, such as measurement and medical fields. Its metal frame and reluctance actuation mechanism ensure reliable operation.

Key Benefits

Cost-effective solution for small diffuser plates

5x5 mm aperture supports high-power laser beams

Compact electronics with closed-loop resonance stabilization

Integrated error signal for system monitoring

Specifications

Product Category: Laser Speckle Reducer

Aperture Diameter: 5 mm

Operating Method: High-speed vibration type

Features: High speckle reduction effect, easy integration, high reliability

Main Applications: Holography, AR/VR, bio/medical imaging
