企業PR

We are a Czech manufacturer of fiber optic and optoelectronic components and assemblies with a tradition dating back to 1994. Our company focuses on the development and production of products based on customer requirements, from prototypes to mass production.

We have an experienced development and manufacturing team that utilizes state-of-the-art technological resources. Our products are used across various industries, as well as in universities and research institutions worldwide.

We are also the founder of the Technical Lyceum in Nová Paka, a modern school providing general education with a strong emphasis on technical and natural sciences. The school prepares students for both university studies and practical work.

We are based in Nová Paka, Czech Republic, where for over three decades, we have been delivering high-quality products to customers across all continents. Our quality and environmental management systems are certified according to ISO 9001 and ISO 14001.

SQS Fiber Optics 取り扱い製品

Fiber Optic Feedthrough

Fiber Optic Feedthrough

Fiber optic feedthroughs and patchcords for reliable optical transmission and hermetic sealing in ultra-high vacuum, high-pressure, and harsh industrial environments. Our solutions ensure long-term durability and stable performance even under extreme conditions such as cryogenic temperatures and radiation exposure.

Single-mode, multimode, and polarization-maintaining fiber configurations integrated into standard or custom flanges (CF, KF, ISO, etc.). Our in-house sealing technology and extensive experience provide high mechanical stability, minimal signal loss, and consistent operation in environments involving vacuum, pressure, oils, aggressive gases, or other extreme physical conditions.

V-groove Fiber Array

V-groove Fiber Array

High-precision custom V-groove fiber arrays for SM, MM, PM, MCF, and UHNA fibers. SQS portfolio includes standard arrays, collimated arrays with microlens arrays (MLA), lidless or recessed-cover variants and UHNA fiber arrays for edge coupling to photonic chips. All array types are available for cryogenic, ultra-high vacuum (UHV), and stress-free fiber bonding applications.

For out-of-plane (vertical) fiber-to-chip coupling, SQS provide low-profile arrays that use total internal reflection on the fiber array’s front facet.

SQS ultra-precise V-grooves are produced with state-of-the-art dicing saws, enabling customer-specific geometries with sub-micron fiber placement accuracy.

2D Matrix Fiber Array

2D Matrix Fiber Array

SQS 2D matrix fiber arrays are manufactured with high fiber positioning accuracy and minimal tilt. SQS provides arrays with fully custom arrangements of SM, PM, MM, UHNA, and MCF fibers.

Fiber end can be terminated with standard connectors such as MPO, MT, MMC, FC, LC, E2000, SC, ST, or with another fiber array. The front facet is precisely polished either flat or at angles of 6° or 8°, or at custom angle. Optionally may be coated with an anti-reflective layer to reduce optical losses. For collimated outputs, an MLA can be actively aligned and bonded to the array.

Laser Systems and Components

Laser Systems and Components

SQS provides advanced laser systems and components for industrial, medical, and scientific applications. The portfolio includes fiber-coupled laser solutions, beam delivery cables, and precision control units designed for reliable performance and high efficiency.

With a focus on customization, SQS develops solutions tailored to specific power, wavelength, and application requirements—ensuring precise, stable, and long-term operation.

Fiber Optic Bundle

Fiber Optic Bundle

SQS solutions enable precise laser power transmission, efficient light coupling, and reliable performance in demanding applications.

Fully customizable designs include flexible fiber arrangements, a wide range of connector interfaces, and multiple fiber types with robust mechanical protection. High-power laser delivery cables feature thermally fused fiber ends and optional anti-reflective coatings for maximum coupling efficiency and stability.

Fiber optic bundles with defined input and output geometries (circular, linear, square), including round-to-linear converters and reflection probes, ensure controlled light distribution and consistent signal transmission. Ideal for spectroscopy, fluorescence microscopy, colorimetry, and advanced optical imaging.

Fiber Optic Collimator

Fiber Optic Collimator

SQS designs and manufactures high-precision fiber optic collimators for demanding industrial, scientific, and sensing applications. Single-channel and multi-channel solutions are available, including fiber arrays and matrix arrays, compatible with SM, MM, and PM fibers.

An advanced active alignment process based on the autocollimation method ensures precise lens-to-fiber positioning and optimal optical performance.

Fiber Optic Cable Assemblies

Fiber Optic Cable Assemblies

SQS produce optical patch cords suitable for high-capacity data transmissions, reference and master patch cords for measurement purposes. High extinction PM patch cords for sensor applications. Optical cables for use in vacuum, outdoor, industrial and defense applications.

The produced optical interconnect cables comply with IEC, CELENEC and Telcordia international standards.

Fiber Optic Rotary Joint

Fiber Optic Rotary Joint

High-performance solution for optical signal transmission during rotation with minimal loss and excellent stability. The compact and durable stainless-steel design ensures reliable operation even in demanding environments requiring continuous rotation. Ideal for a wide range of industrial applications.

Available versions:
Straight single-channel optical rotary joint
Multi-channel optical rotary joint for single-mode and multimode optical signal.
Angled 90° optical rotary joint
